The Safari for Adequate Landing Zones in EVAR Continues: Bilateral Use of Cook Zenith Iliac Branch Devices

The ultimate and durable exclusion of an abdominal aortic aneurysm requires adequate proximal and distal sealing zones. Fenestrated devices offer a solution for proximal extension. However, distal targetting into the external iliac arteries (EIA) denies direct perfusion to the internal iliac arteries and leads to a non-negligible rate of buttock claudication, or even more serious complications, such as bowel ischaemia, plexopathy, or erectile dysfunction. Preserving internal iliac artery (IIA) blood flow was initially achieved with oversized bell bottom components, although deploying these inside unhealthy common iliac arteries has been shown to compromise the durability of the repair.
