DIAS, Emanuel et al. The Zenith iliac bifurcation Device (IBD) for preservation of the internal iliac arteries during endovascular repair of aortic-iliac aneurysms. Angiol Cir Vasc [online]. 2010, vol.6, n.4, pp.207-211. ISSN 1646-706X.

Introduction: A significant portion of patients presenting for endovascular aneurysm repair of the abdominal aorta (EVAR) have aneurysmatic or ectasied common iliac arteries, raising distal anchorage issues. In these cases, it may be necessary occlusion / embolization of one or both hipo gastric arteries with extension of the endoprothesis to the external iliac artery. This procedure has been associated to gluteal claudication, intestinal ischemia, vesical and intestinal disfunction, neurologic deficits and impotence. The use of branched endoprothesis with preservation of the hypgastric artery is a recente innovation to reduce such complications. Clinical case: A 63 year-old male, previously submitted to an open repair of an abdominal aortic aneurysm with an aorto-aortic prothesis, was admitted for endovascular treatment of an aneurysm of the right common and internal iliac arteries with 3,3cm. A Zenith® branched endoprothesis with a branch to the iliac bifurcation was deployed via right femoral access, thus assuring preservation of the hypogastric artery. Conclusion: Hypogastric preservation necessity during EVAR in aorto-iliac aneurysms may be achieved in a secure and simple way through the placement of endoprothesis to the iliac bifurcation.
