Abdominal aortic aneurysmectomy in a renal transplant patient: protection of the kidney without adjunctive measures.
Abdominal aneurysmectomy in kidney transplant recipients can be successfully performed without adjunctive protective measures if the period of renal ischaemia is short. A technique that attains this goal is described here. An aortic aneurysm (5 cm) was removed 2 years after kidney transplantation to the left external iliac vessel. The right common iliac artery was divided first and anastomosed to the right branch of the bifurcated graft. Aortic anastomosis was then performed; the period of renal ischaemia was only 20 min. Arterial flow was re-established in the right common iliac artery, providing profuse collateral flow to the transplanted kidney through the internal iliac arteries during the time necessary to complete the left common iliac artery anastomosis. This procedure is feasible unless the internal iliac artery is severely stenosed, occluded or terminally anastomosed to the transplanted renal artery. In all other cases, this technique may be the optimal procedure to protect the kidney during elective abdominal aorta aneurysmectomy in renal transplant recipients by reducing the period of ischaemia to that of one anastomosis only.
