ABSTRACT Objective To analyze the karyotype test and myeloid panel with next-generation sequencing findings in patients with myelofibrosis, and to compare transplant characteristics in patients referred for bone marrow transplantation. Methods Retrospective, single-center study with patients diagnosed with myelofibrosis treated at Hospital Israelita Albert Einstein between 2010 and 2020. Results A total of 104 patients with myelofibrosis were examined. Patients who had not been submitted to tests in our service were excluded. The final sample comprised 69 patients. Of these 69, 56 were submitted to karyotyping and 22 to myeloid panel with next-generation sequencing. Karyotype was normal in 60% of the patients and altered in 40%. The prevalence of high-risk molecular mutations was higher in patients referred for bone marrow transplantation (100% versus 50%). The median follow-up of transplant patients was 2.4 years and the overall survival at 2 years was 80% (95%CI: 62-100%). Conclusion The molecular analysis enables estimating the patient’s risk and thus instituting more aggressive treatment such as bone marrow transplant for patients at higher risk, being a relevant tool to guide therapy. Given the significance of molecular analysis for therapeutic decision-making in myelofibrosis, collection and disclosure of data on the prevalence of cytogenetic changes and findings of next-generation sequencing in affected patients is important.

ABSTRACT Reference evapotranspiration (ET0) and rainfall are basic variables for estimating the net irrigation depth (NID). The objective of this study was to estimate the NID for designing irrigation systems in Piracicaba, SP, Brazil, using ET0 and rainfall probability distributions. A 30-year ET0 and rainfall dataset (1990-2019) was obtained from the ESALQ/USP weather station. The water balance between ET0 and rainfall indicated July, August, and September as months of higher water deficit. Based on the first-order Markov chain, August presented the highest water deficit. Rainfall and ET0 were estimated on 19 probability levels, and four probability distributions such as normal, log-normal, beta, and mixed gamma were evaluated. The analysis of historical August series using accumulated values in periods of five, ten, or 15 days is recommended for sizing irrigation designs in Piracicaba, SP, Brazil. The log-normal and mixed gamma probability distributions presented the best fit for ET0 and rainfall data, respectively. To reach a crop coefficient Kc = 1 in Piracicaba, SP, Brazil in August, the irrigation system should be designed for an NID of 4.1 mm day-1. The use of mean monthly rainfall and ET0 values for designing irrigation systems underestimates the NID by a mean of 26.6% compared to estimates made at a probability of 75% at five-, ten-, and 15-day intervals because the mean rainfall values occurred with exceedance probabilities of < 36%, and mean ET0 values occurred with non-exceedance probabilities of < 56%.

Abstract BRS TR271 is a new wheat cultivar released by Embrapa for Brazilian wheat-growing regions 1 and 2 of Rio Grande do Sul, Santa Catarina, and Paraná. It has high grain yield potential and a super-early cycle. It is widely adapted and is classified as bread wheat.

SUMMARY: The celiac, cranial mesenteric and celiacomesenteric ganglia of the paca (Cuniculus paca) were found between the celiac and cranial mesenteric arteries. Two predominant patterns were found: isolated celiac and cranial mesenteric ganglion and the celiacomesenteric ganglion. At the microscopic level, the ganglia are constituted by an agglomeration of neurons surrounded by capsule of connective tissue. Most of these neurons had a single eccentric nucleus. Satellite cells and mast cells were found around the soma. The mast cells were also found ar ound blood vessels and in the capsule of the ganglia.

RESUMEN: Los ganglios celíacos, mesentérico-craneales y celíaco mesentéricos de la paca (Cuniculus paca) se encontraron entre las arterias celíaca y mesentérica craneal. Se visalizaron dos patrones predominantes: celiaca aislada y ganglio mesentérico craneal y ganglio celiaco mesentérico. A nivel microscópico, los ganglios están constituidos por una aglomeración de neuronas rodeadas por una cápsula de tejido conectivo. La mayoría de estas neuronas tenían un solo núcleo excéntrico. Se encontraron células satélites y mastocitos alrededor del soma. Los mastocitos también se encontraron alrededor de los vasos sanguíneos y en la cápsula de los ganglios.

Abstract Background In the investigation of cardiac rhythm disorders, a normal electrophysiological (EPS) study is associated with a favorable prognosis. One of the normality criteria is established by conduction intervals within expected range. Objective To establish reference values in EPS for the intracavitary conduction intervals (PA, AH and HV) in a Brazilian population. Methods A retrospective cohort study of the first 1,500 patients submitted to EPS ablation was performed at Instituto de Cardiologia do Rio Grande do Sul, Brazil. The EPS was considered normal if the test was performed for diagnostic purpose; absence of induced arrhythmias; and conduction intervals within the expected range. The REDCap software was used for data collection and management, and the SPSS Statistics 22.0 used for data analysis. Continuous variables were compared with Student's t-test for independent samples and categorical variables with the chi-square test (X 2 ). Values of p ≤ 0.05 were considered significant. Results A total of 124 (8.3%) with EPS considered normal were included; mean age was 52 ± 21 years, and 63 were male. The mean values in milliseconds of PA, AH and HV were 23 ± 9, 88 ± 25 and 44 ± 7, respectively. The PA, AH, and HV percentile ranges were 13 - 25, 81-107 and 40 - 52, respectively. When the patients were divided into three age groups (1 to 18 years, 19 to 64 years and 65 or more), we observed that the group of older patients had significantly higher values of PA, AH and HV compared with younger patients. Conclusion This study showed that intracavitary conduction intervals in a sample of the Brazilian population were similar to previously published studies. Elderly patients tend to have higher values of intracavitary conduction intervals in EPS. Future studies including broader age ranges could enable the acquisition of more reliable and reproducible reference values. (Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0)

Abstract Background: Postoperative atrial fibrillation (POAF) after cardiac surgery has great clinical and economic implications. Many attempts have been made to identify risk factors aiming at a better evaluation of prophylactic treatment strategies. Objective: To perform an internal validation of a risk score for POAF. Methods: A prospective cohort of 1,054 patients who underwent myocardial revascularization and/or valve surgery was included. The risk score model was developed in 448 patients, and its performance was tested in the remaining 606 patients. Variables with a significance level of 5% in the cohort were included and subjected to a multiple logistic regression model with backward selection. Performance statistics was performed using the c-statistic, the chi-square and the Hosmer-Lemeshow (HL) goodness-of-fit, Pearson's correlation coefficient. Results: Four variables were considered predictors of outcome: age (≥ 70 years), mitral valve disease, the non-use or discontinuation of beta-blockers and a positive water balance (> 1,500 mL). The ROC curve was 0.76 (95% confidence interval [CI]: 0.72-0.79). The risk model showed a good ability according to the performance statistics - HL test x(2) = 0.93; p = 0.983 and r = 0.99 (Pearson's coefficient). There was an increase in the frequency of POAF with the increase of the score: very low risk = 0.0%; low risk = 3.9%; intermediate risk = 10.9%; and high risk = 60.0%; p < 0.0001. Conclusion: The predictive variables of POAF allowed us to construct a simplified risk score. This scoring system showed good accuracy and can be used in routine clinical practice.

ABSTRACT Introduction: Despite the many published techniques, there are difficulties in satisfactorily achieving a nipple areola complex (NAC) with long-lasting results. The objective is to demonstrate results using the triangular cutaneous flap technique in nipple reconstructions and compare it with previously published techniques. Methods: A prospective study of nipple reconstruction using the triangular cutaneous flap technique from January 1, 2015, to March 1, 2016. Surgical technique: Marking of an equilateral triangle; decortication of the three points of the triangle that are united in the form of an envelope, with the central area adhered to the neo-breast; total skin grafting for construction of the areola. The patients were evaluated and results classified as fully satisfactory, satisfactory, partially satisfactory, or unsatisfactory. Primary type of breast reconstruction, postoperative or neoadjuvant chemo- or radiotherapy complications, comorbidities, and postoperative complications were evaluated. Statistical evaluation was performed using Fisher’s exact test, chi-square test, and post hoc analysis (significance p < 0.05). Results: Thirty-one patients underwent nipple reconstruction using the triangular cutaneous flap technique, 17 unilateral and 14 bilateral, totaling 45 reconstructions. Mean age was 50 years, mean body mass index was 24.95 kg/m 2, and mean follow-up period was 14 months. Rated: demographic data, complications of patients versus the type of primary breast reconstruction and completion of chemo- and/or radiotherapy, types of breast reconstruction performed, evaluation of the nipples versus reconstruction, evaluation of the nipple reconstruction technique versus satisfaction of evaluators, and nipple complications versus reconstruction technique. Conclusion: The original triangular cutaneous flap technique presents the advantages of easy execution and safety in reconstruction of the NAC.

Resumen: La ablación de la fibrilación auricular mediante el aislamiento de las venas pulmonares, es una estrategia ampliamente utilizada en la actualidad. La recurrencia posablación es un problema frecuente. Se han investigado varios predictores de recurrencia con el fin de optimizar la elección del paciente que más se beneficia del procedimiento. Actualmente la evidencia es controvertida, siendo necesarios más estudios al respecto.

Summary: The ablation of atrial fibrillation based on pulmonary veins isolation, is a widely used strategy nowadays. Post ablation recurrence is a frequent problem. Several recurrence predictors have been researched, with the purpose of choosing the patient that would benefit the most from this procedure. Current evidence is controversial and more research is needed.

ABSTRACT Introduction: Weight reduction achieved after bariatric surgery can result in deformities of various parts of the body. The need for reduction of leftover skin and body remodeling makes patients seek body contouring surgery to improve their quality of life. The aim of the study was to present a protocol for post-bariatric plastic surgery at Daher Hospital. Methods: This was a retrospective longitudinal observational study. As routine protocol, we divided the procedures into two steps, performed in different surgical stages, which we termed the two-level principle. Herein we describe the routine of pre, intra, and postoperative care, as well as details of the surgical techniques. Photographic images were analyzed by an external evaluator. Results: The study included 13 ex-obese patients, with a mean age of 44 years. Of them, 6 patients underwent lower- and upper-level surgeries and another 6 underwent lower-level surgeries. The mean surgical time for the lower level was 4 hours and 54 minutes and that for the upper level was 4 hours and 5 minutes. A total of 92.30% of the patients were satisfied with the results. An external evaluator classified 92.30% of the cases as good or great. Conclusion: Circumferential abdominoplasty has immense benefits and complementary surgeries are vital for a satisfactory result. Reduction of the surgical time requires great synchronization of the surgical team, which allows procedures to be performed simultaneously by multiple surgical teams working in different body parts. Satisfactory results and low complication rates allow the applicability of our routine in post-bariatric patients.

RESUMO Introdução: Redução ponderal conseguida após cirurgia bariátrica pode resultar em deformidades de diversos segmentos corporais. Necessidade da redução das sobras de pele e da remodelação do corpo faz com que a cirurgia do contorno corporal seja procurada por pacientes para melhorar a qualidade de vida. Objetivo do estudo é apresentar a rotina de cirurgia plástica pós-bariátrica do Hospital Daher. Métodos: Estudo observacional longitudinal retrospectivo. Como rotina, dividimos os procedimentos em duas etapas realizadas em atos operatórios distintos: princípio dos dois andares. Descrevemos a rotina dos cuidados pré, intra e pós-operatório, bem como detalhes das técnicas cirúrgicas. Imagens fotográficas foram analisadas por um avaliador externo. Resultados: Estudo composto 13 pacientes ex-obesos, média de idade de 44 anos. Seis pacientes foram submetidos a cirurgia do andar inferior e superior e outros 6 apenas do andar inferior. Tempo médio da cirurgia do andar inferior foi de 4 horas e 54 minutos e do andar superior foi de 4 horas e 5 minutos. 92,30% dos pacientes mostraram-se satisfeitos com o resultado. Avaliação externa revelou uma taxa de 92,30% dos casos classificados como bons ou ótimos. Conclusão: Abdominoplastia circunferencial traz grandes benefícios e as cirurgias complementares são primordiais para um resultado satisfatório. Redução do tempo cirúrgico exige grande sincronização da equipe cirúrgica, permitindo realizar procedimentos combinados por times cirúrgicos trabalhando em compartimentos corporais diferentes, em tempo simultâneo. Resultados satisfatórios obtidos e baixos índices de complicação possibilitam aplicabilidade da nossa rotina em pacientes pós-bariátricos.

Resumo Fundamento: Síndrome de Brugada (SBr) é uma condição arrítmica definida por anormalidades do segmento ST-T em derivações V1-V3 associada a risco elevado de arritmias ventriculares e morte súbita. Dados locais quanto às características clínicas dos pacientes com padrão eletrocardiográfico (ECG) típico avaliados por estudo eletrofisiológico (EEF) são escassos. Objetivo: Avaliar pacientes com padrão ECG sugestivo de SBr encaminhados para EEF em um centro especializado. Métodos: Estudo de coorte de casos encaminhados para EEF por padrão ECG compatível com SBr, entre janeiro de 1998 e março de 2017. Resultados: Dos 5506 procedimentos, 35 (0,64%) foram para investigação de SBr. Vinte e cinco (71,42%) eram homens. Idade média 43,89 ± 13,1 anos. Apresentação ECG foi tipo I em 22 casos (62,85%), tipo II em 12 (34,30%) e tipo III em 1 (2,85%). Vinte e três (65,7%) eram assintomáticos, 6 (17,14%) apresentavam palpitações, 5 (14,3%) síncope, 3 (8,6%) história familiar de morte súbita. Estudo eletrofisiológico induziu taquiarritmias ventriculares em 16 casos (45,7%), sendo o período refratário ventricular médio de 228 ± 36 ms. Utilizou-se ajmalina/procainamida em 11 casos (31,4%), sendo o padrão ECG transformado em tipo I em 7 (63,6%). Dezesseis casos (45,7%) receberam cardiodes fibrilador (CDI). Em seguimento médio de 5 anos, 1 dos 16 pacientes (6,25%) com CDI teve terapia apropriada para fibrilação ventricular. Nenhuma morte foi registrada. Outras arritmias ocorreram em 4 (11,4%) casos. Conclusões: Homens são maioria, sendo o padrão ECG tipo I a principal indicação de EEF. Droga classe IA possui alta taxa de conversão do padrão ECG. A taxa de eventos no CDI foi de 6%.

Abstract Background: Brugada syndrome (SBr) is an arrhythmic condition characterized by ST-T segment abnormalities in the right precordial leads associated with a high risk of ventricular arrhythmias and sudden death. Local data regarding the clinical characteristics of patients with a typical electrocardiographic (ECG) pattern undergoing electrophysiological study are scarce. Objective: To evaluate patients with an ECG pattern suggestive of SBr referred for electrophysiological evaluation in a specialized center. Methods: Cohort study of patients referred for electrophysiological study because of an ECG pattern compatible with SBr between January 1998 and March 2017. Results: Of the 5506 procedures, 35 (0.64%) were for SBr investigation, 25 of which (71.42%) were performed in men. The mean age was 43.89 ± 13.1 years. The ECG patterns were as follows: type I, 22 (62.85%); type II, 12 (34.30%); and type III, 1 (2.85%). Twenty-three patients (65.7%) were asymptomatic, 6 (17.14%) had palpitations, 5 (14.3%) had syncope, and 3 (8.6%) had a family history of sudden death. Electrophysiological study induced ventricular tachyarrhythmias in 16 cases (45.7%), the mean ventricular refractory period being 228 ± 36 ms. Ajmaline / procainamide was used in 11 cases (31.4%), changing the ECG pattern to type I in 7 (63.6%). Sixteen cases (45.7%) received an implantable cardioverter defibrillator (ICD). In a mean 5-year follow-up, 1 of the 16 patients (6.25%) with ICD had appropriate therapy for ventricular fibrillation. There was no death. Other arrhythmias occurred in 4 (11.4%) cases. Conclusions: Most patients are men, and a type I ECG pattern is the main indication for electrophysiological study. Class IA drugs have a high ECG conversion rate. The ICD event rate was 6%.

ABSTRACT Introduction: A total of 57,960 new cases of breast cancer were expected in Brazil in 2016 according to data from the National Cancer Institute, corresponding to 25% of cancers in the country (excluding non-melanoma skin tumors). This study aims at presenting a surgical approach for immediate breast reconstructions with upper retropectoral and lower mixed subcutaneous cavities. Methods: The authors performed breast reconstruction using flaps of the pectoral muscle and inferior cutaneous pedicle associated with insertion of silicone breast implants. The medical records of patients operated between 2012 and 2016 at the Plastic Surgery Service of the senior author’s private clinic at Daher Hospital and Armed Forces Hospital were retrospectively analyzed. Results: The results were satisfactory, with low complication rates and high patient and author satisfaction. Thirty-six patients, with a mean age of 59 years, underwent breast reconstruction using the described technique. The complications were nipple-areola complex necrosis, dehiscence, seroma, hematoma, liponecrosis, implant displacement, and deep venous thrombosis. No patient needed salvage surgery or had recurrence of mammary neoplasia during the study period. Conclusion: The present technique preserves the skin located at the lower portion of the breast, with a low risk of dehiscence or extrusion of the implant in this region, providing a double protection of the implant, with the pectoralis major muscle in the upper two thirds and the cutaneous-dermis-fat flap in the lower third, characterizing a “dual-plane” positioning.

RESUMO Introdução: Segundo dados do Instituto Nacional de Câncer (INCA) de 2016, estima-se em 57.960 novos casos de câncer de mama no Brasil, o que corresponde a 25% dentre todos os tipos de cânceres no país (excluindo-se os tumores de pele não melanoma). O presente artigo visa apresentar uma forma de abordagem para as reconstruções mamárias imediatas com loja retropeitoral superior e subcutânea mista inferior. Métodos: Os autores descrevem da técnica de reconstrução mamária com retalho do músculo peitoral e pedículo cutâneo inferior, associado à inclusão de implante mamário de silicone. Foi realizada análise retrospectiva de prontuários das pacientes operadas entre os anos 2012 e 2016 no Serviço de Cirurgia Plástica da clínica privada do autor sênior, no Hospital Daher e no Hospital das Forças Armadas. Resultados: Os resultados são satisfatórios, com baixos índices de complicações e com satisfação elevada para os pacientes e os autores. Trinta e seis pacientes foram submetidas à reconstrução mamária com a técnica descrita, com média de idade de 59 anos. As complicações apresentadas foram necrose de complexo areolopapilar, deiscência, seroma, hematoma, liponecrose, deslocamento do implante e trombose venosa profunda. Nenhuma paciente teve necessidade de resgate da reconstrução ou apresentou recidiva da neoplasia mamária durante o período do estudo. Conclusão: Trata-se de técnica que preserva a pele da mama em sua parte inferior, com baixa possibilidade de deiscência ou extrusão do implante nesta região, proporcionando uma dupla proteção deste implante com o músculo peitoral maior nos dois terços superiores e o retalho cutâneodermogorduroso no terço inferior, caracterizando um “dual-plane”.

Resumo Fundamento: O uso ininterrupto de anticoagulação oral (ACO) com antagonistas da vitamina K (AVKs) para procedimentos de eletrofisiologia está sendo cada vez mais recomendado. A prática clínica em nosso serviço é de uso continuado dessas drogas para ablação de flutter atrial. Existem poucas evidências quanto ao uso ininterrupto dos anticoagulantes orais não antagonistas da vitamina K (NOACs) nesse cenário. Objetivos: Comparar as taxas de complicações relacionadas ao uso ininterrupto de diferentes tipos de anticoagulantes orais em pacientes referidos para ablação por flutter atrial (FLA). Métodos: Coorte histórica e unicêntrica dos procedimentos de ablação por FLA realizados no período de novembro de 2012 a abril de 2016. O desfecho primário foi o de ocorrência de complicação hemorrágica ou embólica durante o procedimento. O desfecho secundário foi o de ocorrência de acidente vascular cerebral (AVC) ou acidente isquêmico transitório (AIT) no acompanhamento. O nível de significância estatística adotado foi de 5%. Resultados: Foram incluídas 288 ablações por FLA; 154 foram feitas com uso ininterrupto de ACO (57,8% com AVK e 42,2% com NOAC). A idade média foi de 57 ± 13 anos. A taxa de complicação hemorrágica durante o procedimento foi de 3% em cada grupo (p = NS). A taxa de AVC/AIT foi, respectivamente, de 56/1.000-pessoas-ano no grupo AVK contra zero/1.000-pessoas-ano no grupo NOAC (p = 0,02). Conclusão: Em nossa população não ocorreram complicações hemorrágicas relacionadas ao procedimento com uso de ACO de forma ininterrupta, incluindo NOACs. Houve maior ocorrência de AVC/AIT no seguimento no grupo de pacientes em uso de AVK, contudo essa diferença pode não ser decorrente apenas do tipo de ACO em uso.

Abstract Background: The uninterrupted use of oral anticoagulation (OAC) with vitamin K antagonists (VKAs) for electrophysiology procedures has been more and more recommended. The clinical practice in our service recommends the continuous use of these drugs for atrial flutter ablation. There is little evidence as to the uninterrupted use of non-vitamin K antagonist oral anticoagulants (NOACs) in this scenario. Objective: To compare the rates of complications related with the uninterrupted use of different types of oral anticoagulants in patients referred to atrial flutter (AFL) ablation. Methods: Historical, single-center cohort of ablation procedures by AFL conducted from November 2012 to April 2016. The primary outcome was the occurrence of hemorrhagic or embolic complication during the procedure. The secondary outcome was the occurrence of stroke or transient ischemic attack (TIA) in follow-up. The statistical significance level was 5%. Results: There were 288 ablations per AFL; 154 were carried out with the uninterrupted use of OAC (57.8% with VKA and 42.2% with NOAC). Mean age was 57 ± 13 years. The rate of hemorrhagic complication during the procedure was 3% in each group (p = NS). The rate of stroke/TIA was, respectively, of 56/1,000 people-year in the VKA group against zero/1,000 people-year in the NOAC group (p = 0.02). Conclusion: In our population there were no hemorrhagic complications regarding the procedure of OAC use uninterruptedly, including NOACs. There was higher occurrence of stroke/TIA in the follow-up of the group of patients undergoing VKAs; however, this difference may not only be a result of the type of OAC used.

ABSTRACT Introduction: The paper describes a 14-year experience with breast reconstruction using a latissimus dorsi myocutaneous flap (LDMF) and breast implants. The objective was to delineate the experience with LDMF and breast implants, skin island schedules and dissection details, flap transposition and placement of the implant under a double layer, strategies to minimize damage in the donor area, and strategies of breast symmetry and reconstruction of the nipple-areola complex, in association with evaluation using the Breast-Q questionnaire. Methods: A review of medical records was performed between April 2003 and June 2017. Results: In the period, 76 patients with a mean age of 50.09 years underwent reconstruction with a LDMF, which was bilateral in 11, for the right breast in 34, for the left breast in 31, immediate in 41, late in 22, and for rescue in 13. Conclusion: We conclude and verified with the Breast-Q questionnaire that with a precise indication, the proposed reconstruction technique with a double subpectoral plane and coverage with a LDMF is safer with a lower complication rate.

A média de satisfação foi 72,36% por meio do Breast-Q. Conclusão: Concluímos e comprovamos com o questionário do Breast-Q que a indicação precisa aliada a técnica de reconstrução proposta com plano duplo subpeitoral associada a cobertura do RDG, propicia uma loja mais segura, diminuído o índice de rippling.

ABSTRACT Introduction: The nasal tip is a frequent object of study by surgeons, since it is a common reason for preand postoperative complaints. Thus, the tip should be thoroughly evaluated to determine the best technique to be used. The objective is to demonstrate an original alar cartilage flap technique for projection of the nasal tip, performed alone or in combination with other procedures for the same purpose. Method: A retrospective cross-sectional study of 22 patients submitted to open rhinoplasty with use of the alar flap to project the nasal tip. Results: A total of 22 open rhinoplasties were performed on primary bulbous, fatty, and under-projected tips. Among the patients in the study, 90% were black and 2% were white; 72.7% reported a high degree of satisfaction with the operation, 18.1% considered the result very good, and 9.2% considered the result acceptable. There were no complications/reoperations. Conclusion: The alar cartilage flap for projection of the nasal tip is simple to perform and can be considered an excellent supplemental method for use in treatment of the black nose.

Dentre os pacientes do estudo, 90% eram negros e 2% eram brancos, 72,7% apresentaram alto grau de satisfação com a operação, 18,1% consideraram o resultado muito bom e 9,2% acharam regular. Não houve complicações/reoperações. Conclusão: Os retalhos de cartilagens alares para projeção da ponta nasal são um recurso técnico de simples execução e podem ser considerados excelente recurso de projeção adicional da ponta nasal a ser considerado dentre as técnicas para tratamento de narizes negroides.

ABSTRACT Introduction: This work describes and presents the results of an alternative technique for treating steatonecrosis by liposuction using a specific cannula, with good physical and imaging results. Steatonecrosis is a complication that frequently occurs during mammary surgeries, especially during mammary reconstructions and in conservative surgery or TRAM. Steatonecrosis is characterized initially by hardening of the tissue that may develop into nodules of different sizes in any mammary region with oily cysts and fibrosis; consequently, steatonecrosis is a constant concern for patients, oncologists, breast cancer specialists, and plastic surgeons due to the possibility of tumor recurrence. Method: A retrospective review of the medical records of the patients undergoing procedures related to the breast, either reconstructive or aesthetic, was performed. Patients who developed steatonecrosis and were treated by liposuction, similar to the bone drilling technique performed by orthopedic surgeons for the treatment of bone necrosis, were included in the study. Results: Eight patients from the study period reviewed were selected. The mean age was 56 years. Most of the patients showed deformity in the affected breast, with oily cysts, reported in 5 patients (62.5%), being the most common deformity. Breast cancer history was reported for 75% of the patients. Conclusion: The individualization of the patient is the key to successful treatment of steatonecrosis and an essential tool to satisfy the expectations and desires of the patient after this complication. Each technique has its indications, advantages and limitations, which should be thoroughly discussed with the patient to obtain the best possible result.

RESUMO Introdução: Este trabalho descreve e apresenta os resultados de uma técnica alternativa para tratamento da esteatonecrose, a lipoaspiração com cânula específica, com bons resultados observados no exame físico e de imagem. A esteatonecrose é uma complicação que ocorre com alguma frequência nas cirurgias mamárias, principalmente nas reconstruções mamárias, nas cirurgias conservadoras ou TRAM, caracterizando-se, inicialmente, por endurecimento de uma região, que evolui para uma nodulação de tamanhos variados, em qualquer região mamária, com cistos oleosos e fibrose, que traduz uma preocupação constante por parte das pacientes, do oncologista, do mastologista e do cirurgião plástico devido à ocorrência de recidiva tumoral. Método: Foi realizada uma revisão retrospectiva dos prontuários das pacientes submetidas a procedimentos nas mamas, seja reconstrução ou estética, e evoluíram com esteatonecrose, sendo submetidas ao tratamento com lipoaspiração, inspirada na técnica de perfuração óssea para tratamento de necrose óssea, realizado por ortopedistas.
