Abstract

Renal artery pseudoaneurysms are uncommon vascular lesions that require a high degree of suspicion because they are usually difficult to diagnose. Posttraumatic renal artery pseudoaneurysms should be treated because spontaneous resolution is extremely unusual, and the risk of aneurysm rupture is high. We describe the case of a patient who presented with a pulsatile mass in the right upper quadrant and recurrent abdominal pain 18 months after blunt trauma. Arteriography and multislice computed tomography angiography revealed a pseudoaneurysm measuring 22 cm in the right renal artery. The patient was successfully treated with conventional open surgery.

Resumo

Pseudoaneurismas de artéria renal são lesões vasculares pouco comuns, que geralmente demandam alto grau de suspeição, por serem de difícil diagnóstico. Considerando a baixa expectativa de resolução espontânea dos PARs pós-traumáticos, aliada ao importante risco de rotura, faz-se necessária a correção destas lesões. Apresentamos o caso de um paciente, vítima de trauma contuso há 18 meses, com queixa de massa pulsátil em hipocôndrio direito associado a dor abdominal recorrente. Depois da arteriografia e angiotomografia multislice, foi diagnosticado um pseudoaneurisma de artéria renal direita com 22 cm de extensão, sendo então submetido a tratamento cirúrgico por via aberta convencional, com sucesso terapêutico.
