Resumo

OBJETIVO: Analisar os resultados de 15 pacientes com elevado risco de sangramento obstétrico, submetidas ao implante de catéteres balão profilático para oclusão temporária das artérias hipogástricas. MÉTODOS: Uma análise retrospectiva foi realizada com base em prontuários de 15 pacientes submetidas ao implante de catéteres balão profilático, de janeiro/2008 a dezembro/2011. Todas as pacientes incluídas no estudo foram diagnosticadas no período antenatal com doença placentária associada a alto risco de hemorragia obstétrica. RESULTADOS: A média de idade das pacientes estudadas foi de 36 anos (32-42 anos). Nove pacientes eram portadoras de acretismo placentário, quatro possuíam placenta prévia, uma estava com gestação ectópica e uma apresentava miomatose uterina e coagulopatia associada a Lupus Eritematosos Sistêmico. O volume total de contraste utilizado para o procedimento variou entre 20 e 160 ml (média de 84 ml). A média do número total de dias de internação e o número de dias de internação após o procedimento foram, respectivamente, 12,4 e 4,9 dias. Em oito (53%) casos, não houve necessidade de transfusão sanguínea no intraoperatório ou após a cirurgia. A média do número de unidades de sangue transfundida foi 2,06. A única complicação associada ao procedimento foi a trombose arterial de artéria ilíaca externa, observada em dois casos. CONCLUSÃO: A oclusão temporária de artérias hipogástricas é um método seguro e efetivo para controle de hemorragia em pacientes com elevado risco de sangramento obstétrico, quando realizado por equipe experiente. Os resultados deste estudo são observacionais, retrospectivos e não randomizados; portanto, não podemos apoiar o uso rotineiro dessa técnica, mas podemos incluí-la no arsenal de recursos para casos selecionados com potencial para sangramento.

Abstract

OBJECTIVE: To analyze the results of 15 cases of patients at high risk of obstetric hemorrhage who underwent prophylactic temporary occlusion of internal iliac arteries. METHODS: A retrospective analysis was performed of the medical records of 15 patients who underwent prophylactic balloon occlusion of the internal iliac arteries between January 2008 and December 2011. All patients included in the study were diagnosed antenatally with a placental disease associated with a high risk of obstetric hemorrhage. RESULTS: The mean age of the patients studied was 36 years (32-42 years). Nine patients had placenta accreta, 4 had placenta previa, 1 had an ectopic pregnancy and 1 had uterine fibroids and coagulopathy associated with systemic lupus erythematous. The total volume of contrast used in each procedure ranged from 20 to 160 ml (mean 84 ml). The average total number of days in hospital and the average number of days in hospital after the procedure were 12.4 and 4.9 days respectively. In 8 (53%) cases there was no need for blood transfusion during surgery or after surgery. The mean number of units of blood transfused was 2.06. The only complication associated with the procedure was arterial thrombosis of the external iliac artery, observed in 2 cases. CONCLUSION: Temporary occlusion of hypogastric arteries is a safe and effective method for control of bleeding in patients at high risk of obstetric hemorrhage, when performed by experienced staff. The results of this study are observational, retrospective and nonrandomized, therefore we cannot support the routine use of this technique, however, we can include it our arsenal to treat selected cases with potentially unstable hemodynamics.
