    Abstract:
    Renal artery aneurysms (RAAs) is a rare clinical entity: the prevalence is approximately 0.01%-1% in the general population. Complex aneurysms of the first ramification of the main renal artery often require nephrectomy for adequate excision. From December 2002 to July 2007, we treated 3 patients with complex RAA. All the patients were treated with ex vivo reconstruction of the renal artery followed by autotransplantation of the kidney into the ipsilateral iliac fossa. Observation is suggested for asymptomatic complex renal artery aneurysms measuring less than 2 cm in diameter. Surgical treatment by aneurysmectomy and reconstruction in vivo or ex vivo technique is indicated for RAA causing renovascular hypertension, dissection, embolization, local expansion and for those in women of childbearing age with a potential for pregnancy, or asymptomatic more than 2 cm in diameter. Ex vivo repair and renal autotransplantation is a safe and effective treatment for the management of complex renal artery aneurysms.
