Ex vivo repair and autotransplantation for a complex renal artery aneurysm

Abstract Renal artery aneurysms (RAA) are rare, occurring with an incidence of <0.1%. Open repair remains the mainstay of treatment for anatomically complex aneurysms. Here, we present a case of a large hilar RAA managed with ex vivo reconstruction and heterotopic renal autotransplantation. In th...

Summary:Abstract Renal artery aneurysms (RAA) are rare, occurring with an incidence of <0.1%. Open repair remains the mainstay of treatment for anatomically complex aneurysms. Here, we present a case of a large hilar RAA managed with ex vivo reconstruction and heterotopic renal autotransplantation. In this case, the complex anatomy and location of the aneurysm precluded the use of an endovascular approach. In situ repair was deemed unfavorable because of the technical difficulty of the repair with the numerous arterial branches involved, risk of parenchymal injury from prolonged warm ischemic time, restricted surgical field and risk of aneurysm rupture. This case contributes to the literature on laparoscopic nephrectomy, ex vivo repair and autotransplantation as a safe and viable treatment strategy for patients with complex RAA.
