    Abstract:
    PURPOSE: To review the midterm results of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) with the Talent stent-graft. MATERIALS AND METHODS: All patients who underwent EVAR of AAAs with Talent stent-grafts from February 1998 to April 2002 at a single institution were monitored for a minimum of 2 years or until an endpoint of death or rupture was reached. RESULTS: There were 68 eligible patients, who were monitored for a mean period of 39 months (range, 24-72 months). Forty-nine (72.9%) were alive at 2 years; among the 19 deaths, two resulted from aneurysm rupture and the other 17 were unrelated to EVAR. There was one immediate conversion to open repair and five primary proximal endoleaks; the remaining 62 patients (91.2%) all had a technically successful procedure. There were 33 endoleaks during follow-up: 23 (69.7%) were treated conservatively and 10 (30.3%) underwent secondary intervention in the form of embolization (n=2), attempted embolization (n=2), endovascular stent-graft placement (n=3), combined stent-graft placement and embolization (n=1), or surgical conversion (n=2). Overall, there were five persistent endoleaks, and the remaining patients were free of endoleak at their last review or endpoint. Three stent-grafts migrated and required further endovascular intervention. Wire fracture was seen in two stents but presented no clinical sequelae. There was one case of graft limb thrombosis that required surgical thrombectomy. CONCLUSIONS: EVAR of AAAs with use of the Talent stent-graft is a promising and acceptable alternative to open surgery. Our 30-day mortality rate of zero compares extremely well with historical data from open surgery and the findings of more recently published trials. The risk of endoleak and uncertainty over durability require long-term surveillance.
