Abstract

Abstract: A 45-year-old woman with known hypothyroidism and no other comorbidities was incidentally found to have multiple right renal artery aneurysms. The largest aneurysm measured 5 x 4.5 cm and arose from an inferior segmental branch while two smaller aneurysms arose from an upper segmental branch of the right renal artery. We performed an ex-vivo repair with reverse saphenous vein graft under cold preservation followed by orthotopic kidney auto-transplantation. Her postoperative course was unremarkable and at 1-year follow-up her right kidney is preserved. In this article, we report successful treatment of complex multiple right renal artery aneurysms and describe the surgical technique used for successful repair.

Resumo

Resumo: Uma mulher de 45 anos com hipotireoidismo conhecido e sem outras comorbidades teve achado incidental de múltiplos aneurismas da artéria renal direita. O maior aneurisma media 5 x 4,5 cm e tinha origem no ramo segmentar inferior, juntamente com dois pequenos aneurismas originários do ramo segmentar superior da artéria renal direita. Realizamos o reparo ex vivo com enxerto reverso de veia safena, sob preservação a frio, seguido de autotransplante renal ortotópico. O pós-operatório ocorreu sem intercorrências, e a paciente teve o rim direito preservado no seguimento de 1 ano. Neste artigo, relatamos o tratamento bem-sucedido de múltiplos aneurismas complexos da artéria renal direita e descrevemos a técnica cirúrgica utilizada para o reparo bem-sucedido.
