title: Chimney stent graft for endovascular sealing of a pararenal aortic aneurysm.
abstract: Chimney endovascular aneurysm repair is still a controversial treatment of complex aortic aneurysms. Stent-graft patency and type-I endoleaks are the main challenges that temper this bailout technique. Endovascular aneurysm sealing (EVAS) consists of anchoring and sealing the device within the aneurysm sac. The first results are promising, even for adverse anatomy. We describe a case of EVAS for a pararenal aortic aneurysm associated with a chimney stent graft for the right renal artery. Wrapping the chimney stent graft inside endobags filled with polymer is expected to prevent gutters and stent compressions.
