Resumo

OBJETIVO: Discorrer sobre os aspectos clínicos e o tratamento cirúrgico de uma série de casos de aneurismas isolados das artérias ilíacas. MÉTODOS: Foram analisados retrospectivamente os dados protocolados e os prontuários de 12 pacientes com diagnóstico de aneurisma isolado das artérias ilíacas, operados no Departamento de Cirurgia da Santa Casa de São Paulo, no período de novembro de 1999 a fevereiro de 2003. RESULTADOS: A freqüência do aneurisma isolado das artérias ilíacas foi de 1,5% dos aneurismas abdominais operados no período do estudo. A faixa etária variou entre 56 e 80 anos, 33% dos doentes apresentavam aneurisma bilateral, e os diâmetros dos aneurismas variaram entre 2,0 e 8,5 cm. Em 83% dos casos, os pacientes encontravam-se sintomáticos no momento do tratamento. Em nenhum dos casos o aneurisma se encontrava roto. A via de acesso utilizada nos aneurismas unilaterais foi a extraperitoneal homolateral à dilatação e, nos aneurismas bilaterais, a transperitoneal, longitudinal ou transversa. Não dissecamos o segmento posterior das artérias ilíacas para clampeamento, para evitar a ocorrência de lesão venosa intra-operatória. Não observamos mortalidade no período peroperatório. Em todos os casos, preservamos pelo menos uma artéria ilíaca interna. CONCLUSÃO: A via de acesso para os aneurismas isolados das artérias ilíacas deve ser individualizada. A preservação de pelo menos uma artéria ilíaca interna constitui uma regra a ser observada, bem como deve-se evitar a dissecção circunferencial das artérias ilíacas no intra-operatório.

Abstract

OBJETIVE: To discuss clinical aspects and surgical treatment of a series of cases of isolated iliac artery aneurysms. METHODS: Protocol data and medical charts of 12 patients with diagnosis of isolated iliac artery aneurysm were retrospectively analyzed. The patients underwent surgery at the Department of Surgery of Santa Casa de São Paulo, from November 1999 to February 2003. RESULTS: Frequency of isolated iliac artery aneurysm was 1.5% of abdominal aneurysms who underwent surgery in the period under investigation. Age group ranged between 56-80 years, 33% of patients presented bilateral aneurysm, and aneurysm diameters ranged between 2.0-8.5 cm. In 83% of cases, the patients were symptomatic during treatment. Aneurysms were not ruptured in any case. Extraperitoneal approach ipsilateral to the dilatation was used in unilateral aneurysms, and transperitoneal approach, longitudinal or transverse, in bilateral aneurysms. We did not dissect the posterior segment of the iliac arteries for clamping, in order to avoid intraoperative venous lesion. There were no deaths during the surgery. In all cases, we preserved at least one internal iliac artery. CONCLUSION: Approach to isolated iliac artery aneurysms should be chosen on an individual basis. Preserving at least one internal iliac artery is a rule to be observed. Circumferential dissection of iliac arteries during the surgery should be avoided.
