A steerable sheath to deploy hypogastric bridging stent by contralateral femoral approach in an iliac branch procedure after endovascular aneurysm repair

Aneurysmal degeneration of distal landing zones after endovascular aneurysm repair (EVAR) can be a potential cause of late failure of this technique. Aneurysmal degeneration of common iliac arteries increases the risk of rupture of the iliac aneurysm itself as well as of the abdominal aortic aneurysm owing to aneurysm’s reperfusion as a type Ib endoleak. Reoperation consists in plugging and covering the internal iliac artery (IIA), by extension into the external iliac artery, or preservation of antegrade flow in IIA by iliac branch devices (IBDs) or sandwich technique. The management of common iliac aneurysms after EVAR with the purpose of preserving antegrade flow into IIA generally requires a brachial or axillary access. However, this approach may be theoretically associated with local or systemic complications. We report a case of IBD implanta- tion after EVAR, using a steerable sheath for IIA bridging stent deployment via contralateral femoral approach.
