OPERATIVE REPAIR OF ENLARGING HILAR RENAL-ARTERY ANEURYSM - A CASE-REPORT AND REVIEW OF THE LITERATURE

Repair of distal renal artery aneurysms poses a significant threat to kidney salvage despite improved operative techniques described over th e past decades. The authors describe the case of a seventy-one-year-ol d woman who presented with an enlarging right renal artery aneurysm lo cated at the renal hilum involving the lobar arteries. Operative repai r was accomplished by excision of the saccular posterior wall and reco nstruction with a saphenous vein patch. The ischemia time was thirty-t hree minutes and her postoperative course was uneventful. She was disc harged home on the fifth postoperative day with normal renal function, and the renal arteriogram demonstrated a technically successful opera tion. They review the current literature, and this case is put into pe rspective with the natural history, clinical course, and present treat ment of renal artery aneurysms.
