Laparoscopic-assisted Ex Vivo Reconstruction of Renal Artery Aneurysm with Internal Iliac Artery and Auto-transplantation

Renal artery aneurysms (RAA) represent a complex and an often incidentally found disease commonly treated with endovascular approaches. In cases where in situ approaches are unsuitable, laparoscopic-assisted ex vivo repairs offer significant advantages during and post-surgery. We present a case of a female patient who presented with a long-standing right-sided flank pain. She was diagnosed with bilateral asymptomatic RAAs positioned well into the hilum, therefore making in situ repair infeasible. A laparoscopic-assisted ex vivo repair of the renal artery was performed using a graft from the internal iliac artery, which is a novel approach.
