Resumo

Pseudoaneurysms of gluteal arteries are rare, especially involving the inferior gluteal artery. They are mainly associated with penetrating trauma, infections, or pelvic fractures. A minority of cases are caused by blunt traumas, with only six cases reported in English. We present a case of pseudoaneurysm of the right inferior gluteal artery after a bicycle fall, presenting with a large hematoma in the gluteal region, observed during clinical examination, and significantly reduced hemoglobin. CT angiography revealed a large hematoma, with contrast extravasation and pseudoaneurysm formation. Angiography revealed that the origin of the lesion was in the right inferior gluteal artery. This artery was embolized with coils. After the procedure, the patient was referred to an intensive care unit, from where he was later transferred to a different hospital, with bleeding controlled. Endovascular treatment of these cases is a safe, fast and an effective option.

Abstract

Pseudoaneurismas de artérias glúteas são raros, especialmente os que envolvem a artéria glútea inferior. Eles estão associados principalmente a traumas penetrantes, infecções ou fraturas de pelve. Em uma minoria de casos, são causados por traumas fechados, havendo somente seis casos relatados na literatura. Apresenta-se aqui um caso de pseudoaneurisma da artéria glútea inferior direita após queda de bicicleta, evoluindo com grande hematoma na região glútea ao exame clínico e queda hematimétrica significativa. A angiotomografia revelou um grande hematoma na região glútea, com extravasamento de contraste e formação de pseudoaneurisma no local. A angiografia revelou que a origem da lesão era na artéria glútea inferior direita. Foi realizada embolização dessa artéria com molas. Após esse procedimento, o paciente foi encaminhado para a unidade de terapia intensiva, de onde foi posteriormente transferido para outro hospital, com o sangramento controlado. Para esses casos, o tratamento endovascular é uma opção segura, rápida e efetiva.
