title: Intraoperative salvage of a renal artery occlusion during fenestrated stent grafting.
abstract: A 79-year-old man with a 6-cm juxtarenal abdominal aortic aneurysm was treated by endovascular means with a fenestrated stent graft. The completion angiogram revealed a left renal artery occlusion. A retroperitoneal surgical approach allowed for retrograde catheterization of the occluded covered stent through the left renal artery. The covered stent was reopened by balloon angioplasty. After 2 months, the left renal artery was patent and renal function normal. At 6 months, both renal arteries were fully open on duplex imaging. The open retroperitoneal approach with retrograde catheterization is a bailout technique to avoid loss of a kidney in fenestrated stent grafting.
