Popis: Objective This study assessed the long-term outcome of patients with abdominal aortic and aortoiliac aneurysms treated with the Cook Zenith endovascular graft (Cook Inc, Bloomington, Ind). Methods Between September 1998 and October 2003, 143 patients underwent elective endovascular aneurysm repair (EVAR) using the Cook Zenith endograft. Data from these patients were reviewed from a prospective database in October 2008. Primary outcome measures were overall survival, intervention-free survival, and freedom from aneurysm rupture. Secondary outcome measures were early and late postoperative complications, including endoleaks. Results Mean follow-up was 66.4 months (range, 1.9-121.0 months). Overall survival was 72.1% at the 5-year follow-up and 50.9% at the 8-year follow-up. Intervention-free survival was 77.1% at 5 years and 63.8% at 8 years. There were no reintervention-related deaths. Six patients had a late aneurysm rupture, which was fatal in three. Freedom from aneurysm rupture was 98.1% at 5 years and 91.0% at 8 years. Late complications occurred throughout the follow-up period, with a tendency for aneurysm rupture and surgical conversion to occur at a later stage in the follow-up period. Aneurysm sac enlargement during follow-up was associated with late aneurysm rupture and with the need for reintervention. Conclusion Elective EVAR using the Cook Zenith endograft provides excellent results through a mean follow-up of >5 years. There is a low aneurysm-related mortality and an acceptable rate of postoperative complications and reinterventions. The occurrence of late complications throughout the follow-up period stresses the need for continued postoperative surveillance in EVAR patients.
