Abstract

The early experience of endovascular aneurysm repair (EVAR) using ''first generation'' devices was disappointing. There was an appreciable incidence of delayed, post-EVAR, aneurysm rupture. This was primarily a consequence of structural device failure. These failures provided important lessons for re-design and the modern ''second generation'' devices, including the Zenith (Cook Inc, Bloomington, IN, USA) endograft, are thought to be more reliable, particularly providing better fixation and sealing and also a more durable stent/fabric structure. This article comprises a review of the English literature detailing the endovascular treatment of abdominal aortic aneurysms using the Zenith endograft. It focuses on clinical studies or trials with intermediate to long-term follow-up, and related the literature to our own experience. In the series examined (N.=2 017 patients) the early mortality rate ranged from 0% to 4.1% and the technical success rate from 97.7% to 100%. The re-intervention rate was related to the length of follow-up (6.8% to 14%). Conversion rates were consistently <1%. There was a low incidence of device migration, limb thrombosis, component separation and stent fracture. These data support the ongoing use of the Zenith endovascular graft in patients with abdominal aortic aneurysms suitable for EVAR.
