Apresentamos o caso de um paciente com aneurisma aórtico tóraco-abdominal tipo IV de Crawford submetido à correção híbrida em dois estágios. Inicialmente submetido a implante cirúrgico de prótese de Dacron® com revascularização de todos os ramos viscerais a partir da ilíaca externa esquerda (debranching) e, posteriormente, tratado pela técnica endovascular com endoprótese aorto bi-ilíaca. Após dois anos, o paciente permanece assintomático e em plena atividade laborativa.

We present a case of a patient with Crawford type IV aortic thoracoabdominal aneurysm. The patient underwent hybrid repair in two stages. Initially a Dacron(r) graft was implanted surgically with revascularization of all visceral branches from the left external iliac artery (debranching). On a later date, the second stage of treatment was with an endovascular technique with bi aorto-iliac endoprosthesis. After 2 years the patient remains asymptomatic and in full working activity.

Os autores relatam um caso de abordagem mista para o tratamento endovascular de doença oclusiva da artéria tibial anterior por acesso pedioso retrógrado, no qual a abordagem tradicional anterógrada foi inadequada em vencer uma oclusão. A técnica parece oferecer uma opção para procedimentos endovasculares, que objetivam o tratamento de lesões da artéria tibial anterior em que a via anterógrada convencional mostre-se inadequada.

The authors report the case of mixed approach for endovascular treatment of occlusive disease of the anterior tibial artery by retrograde pedal artery access where the traditional antegrade approach failed to overcome a segmental occlusion. The technique seems to offer an option for endovascular procedures aimed at treating occlusion of the anterior tibial artery in cases where the conventional antegrade approach demonstrates to be inappropriate.

OBJETIVO: Analisar a eficiência da angioplastia primária infra-inguinal como método de salvamento de membros em pacientes portadores de lesões tróficas por isquemia crítica. MATERIAIS E MÉTODOS: Foram analisados 36 pacientes submetidos a angioplastias primárias sem stent. Todos os pacientes apresentavam isquemia crítica com lesão trófica - grau III, categoria 5 de Rutherford -, sendo 17 lesões na artéria femoral superficial, 16 na artéria poplítea e 51 em artérias da perna, totalizando 84 angioplastias. Foram analisadas também as prevalências em relação a sexo, membro afetado, idade e principais comorbidades, sendo tecidas considerações técnicas sobre os procedimentos, assim como os materiais utilizados. RESULTADOS: Considerou-se sucesso quando a lesão trófica que motivou a angioplastia cicatrizou, ou o nível de amputação limitou-se a artelhos ou ao antepé, sem ter havido necessidade de procedimento cirúrgico de reconstituição do fluxo sanguíneo (bypass), independentemente de tempo, drogas associadas e números de desbridamentos realizados. CONCLUSÃO: As angioplastias no segmento femoropoplíteo e infrapoplíteo são procedimentos de elevado sucesso técnico, baixa morbidade e mortalidade, constituindo-se procedimento eficaz em pacientes com isquemia crítica de membro inferior.

OBJECTIVE: To evaluate the efficacy of infra-inguinal, primary angioplasty as a method of limb salvage in patients with trophic lesions secondary to critical ischemia. MATERIALS AND METHODS: Thirty-six patients submitted to primary percutaneous transluminal angioplasty without stenting were evaluated. All of them presented critical limb ischemia with trophic lesion (Rutherford grade III, category 5). Eighty-four angioplasties were performed for 17 lesions in superficial femoral artery, 16 lesions in popliteal artery, and 51 lesions in below-knee arteries. Additionally, prevalence in relation to sex, age, limb involved and main comorbidities have been discussed, with technical considerations regarding procedures and materials utilized. RESULTS: Clinical success has been defined as complete healing of the trophic lesion or amputation level limited to toes or forefoot, not requiring bypass surgery, independently from time, drugs utilized and number of debridement procedures performed. CONCLUSION: Femoropopliteal and belowknee angioplasties present high technical success, low mortality and low complications rates and are highly effective in the treatment of patients with critical lower limb ischemia.

The authors report a case of an abdominal aortic aneurism involving all visceral branches minus the Inferior Mesenteric artery in a 4-year-old girl. There was sugestive evidence that the arterial disease had an inflamatory or infectious etiologic factor. The most probable etiological factors could be salmonelas infection of the arterial wall or Takayasu's disease secondary to tuberculosis. The treatment with antibiotic to salmonelas infection during ten days, followed by tuberculostatic therapy for six months was chosen. Concerning the age, the arteries involved and the inflamatory aspect of the aneurysm, the surgical option became an alternative to the clinic treatment in case of any future evidence of the aneurysm enlargement. The patient became asymptomatic as soon as the antibiotic has been started. The control of the aneurysm evolution will be made by ecography each three months.

A case of a gunshot of the left axilary artery with a giant pseudoaneurism formation with sixteen years of evolution is presented. The 61- years-old male patient present since them a small assintomatic tumoration in infraclavicular localization. In the last eight months the tumor became symptomatic and volumous, reaching 20 cm in diameter, with signals of infection and imminent rupture. The patient was operated on with ligature of the axilary artery and evacuation of the pseudoaneurysm. The surgical handling and endovascular therapeutic options available in the present time are discussed. A short review about the disease as well as a bibliographic update are present. The authors also call attention for the necessity of a correct management of the vascular injures in the event of the first management.
