Abstract
Background
Placenta accreta is an important factor in maternal morbidity and mortality and is responsible for approximately 64% of emergency hysterectomy cases and about 2/3 of cases of puerperal bleeding.
Objectives
To describe a series of cases of prophylactic uterine catheterization performed to prevent significant postpartum bleeding or during caesarean delivery in pregnant women with a previous diagnosis of accretion.
Methods
A retrospective analysis was conducted of medical records of cases of uterine artery catheterization performed during elective or emergency caesarean sections of patients at high risk of postpartum bleeding.
Results
The catheterization of uterine arteries procedure was performed in fourteen patients. Mean duration of surgery and hospital stay were 214.64 minutes (± 42.16) and 7 days, respectively. All patients underwent obstetric hysterectomy. No patient required embolization. There was no bleeding or need to revisit any patient and there were no complications related to puncture. There was one fetal death and no maternal deaths.
Conclusions
In this study, prophylactic uterine artery catheterization with temporary occlusion of blood flow proved to be a safe technique with low fetal mortality, no maternal mortality, and a low rate of blood transfusion and can be considered an important and effective therapeutic strategy for reduction of maternal morbidity and mortality, especially in pregnant women with anomalous placental attachment. Furthermore, the possibility of uterine preservation with the use of this method is an excellent contribution to therapeutic management of this group of patients. However, randomized clinical trials are needed to evaluate the effectiveness of routine use of the technique.
