A new surgical approach for exclusion of renal artery aneurysms avoiding organ ischemia.

INTRODUCTION Surgical treatment of renal artery aneurysms is inevitably associated with temporary renal artery occlusion and risk of ischemic injury. We present a technique for renal artery grafting and aneurysm exclusion without interrupting renal blood flow. REPORT A symptomatic renal artery aneurysm was bypassed with a venous graft between the abdominal aorta and the very distal renal artery utilizing a distal anastomotic device without interruption of renal blood flow. The aneurysm was then excluded by means of hemostatic clips. CONCLUSION The presented surgical technique offers the major advantage of avoiding organ ischemia and accelerating the surgical procedure.
