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 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.

Introduction: True incidence of renal artery aneurysms is unknown but it has been estimated to be around 1 percent. They are usually asymptomatic and diagnosed through imaging studies done for other medical reasons. Those that are more than 2 cm in diameter or any aneurysm in pregnant women should be treated because of an elevated risk of rupture. We present a case of a man with a complex 2.5 cm renal artery aneurysm, successfully treated with ex vivo repair and reimplantation by a multidisciplinary team.
Introducción: La incidencia real de los aneurismas de arteria renal es desconocida, pero se ha estimado en aproximadamente un 1 por ciento. Normalmente los pacientes son asintomáticos y su diagnóstico es habitualmente un hallazgo de estudios de imágenes solicitados por otras causas. El riesgo principal de los aneurismas mayores de 2 cm de diámetro o aquellos en mujeres embarazadas es la rotura. Caso clínico: Presentamos el caso de un hombre con diagnóstico de aneurisma complejo de arteria renal izquierda, que fue sometido a reparación exitosa.

Kidney transplantation, particularly from a living donor, is the treatment of choice for most patients with end-stage renal disease. The superior results achieved with kidney transplantation from living donor. We report a case of transplantation using a kidney with renal arterial aneurysm from a 49-year-old living donor to her 51-year-old brother. A preoperative CT angiogram in a donor candidate showed the right kidney with 6 mm sized saccular aneurysm involves the proximal portion of anterior segmental artery. The kidney was removed by a hand-assisted laparoscopic nephrectomy. After ex vivo aneurysmectomy, the graft was transplanted into the right iliac fossa. The total ischemic time was 62 minutes, and the urine flow was started immediately after declamping. If there are multiple donor candidates of same condition, donor with unilateral renal artery aneurysm should be chosen for transplant. The use of those grafts is safe for both recipients and donors.
