Comparison of aortoiliac repair with iliac branch endoprosthesis versus hypogastric occlusion in aortoiliac aneurysms

BACKGROUND: The CARIBE Study aims to assess the outcome of endovascular repair (EVAR) with iliac branch endoprosthesis (IBE) in patients with aorto-iliac aneurysms extending to iliac bifurcation, comparing these results with those of EVAR with hypogastric occlusion pres¬ ent in the recent published literature. METHODS: Patients with aorto-iliac aneurysms anatomically suitable for EVAR with IBE, are included in the study. RESULTS: Primary safety outcome measure are total and aneurysm related death free survival. Efficacy endpoints include: iliac branch patency, aneurysmal sac exclusion and freedom from reinterventions or conversion to open repair. Patient reported outcomes are evaluated with Walking Impairment Questionnaire (WIQ), International Index of Erectile Function-5 (IIEF-5) and quality of life Euro-Qual EQ-5D Questionnaire. CONCLuSIONS: Comparison with recent hystorical literature obtained in patients with EVAR with HA occlusion will offer data useful for correct information of patients affected by aorto-iliac aneurysms
