Zusammenfassung:A 17-year-old male patient presenting with an abdominal gunshot wound and severe hypovolemic shock was initially operated and presented several injuries to the small bowel and cecum associated with severe hemorrhage. The patient had to be operated twice due to hypothermia, acidosis, and coagulopathy. In the late postoperative period, murmur and fremitus were observed. Angiography revealed a pseudoaneurysm associated with arteriovenous fistulae at the left external iliac vessels. Lesions were repaired with a stent graft placed in the external iliac artery, with a satisfactory outcome. Control computed tomography performed 6 months later evidenced artery integrity with closure of the fistulae. Endovascular therapy should be the preferred method in this type of vascular trauma complications. Um paciente do sexo masculino com 17 anos de idade apresentando-se com ferimento abdominal por arma de fogo e choque hipovolêmico grave foi inicialmente operado e apresentava várias lesões no intestino delgado e ceco associadas a hemorragia grave. O paciente teve que ser operado duas vezes devido a hipotermia, acidose e coagulopatia. No período pós-operatório tardio, foram observados sopro e frêmito. Angiografia revelou um pseudoaneurisma associado a fístulas arteriovenosas nos vasos ilíacos externos ao lado esquerdo. As lesões foram tratadas mediante a colocação de stent na artéria ilíaca externa, com desfecho satisfatório. Tomografia computadorizada de controle realizada após 6 meses evidenciou integridade da artéria, com o fechamento das fístulas. O tratamento endovascular deve ser o método de escolha nesse tipo de complicação vascular traumática.
