Renal artery aneurysm. Ex vivo repair and autotransplantation

Reconstructive surgery for renal artery aneurysm requires adequate exposure and meticulous dissection. We report 9 patients with 17 aneurysms undergoing ex vivo aneurysmectomy. The reconstructions included vessel plasties, vein and arterial interponates, followed by autotransplantations to the iliac fossae. All kidneys functioned spontaneously, and all survived. Observation times of up to 7 years have now elapsed. Microsurgery and modern preservation techniques in the extracorporeal setting have extended the borders of renal artery surgery.
