Acute bilateral renal artery chimney stent thrombosis after endovascular repair of a juxtarenal abdominal aortic aneurysm

The use of “chimney” stents to augment the proximal landing zone for endovascular aneurysm repair has been increasingly reported.

Here, we report management of a patient presenting with acute bilateral renal chimney stent thrombosis and a type Ia endoleak.
