Background: In the present study, we compared early results of Endurant (Medtronic) stent grafts used in the treatment of abdominal aortic aneurysms with Talent (Medtronic) endografts.

Methods: In 12 patients (1 female, 11 males; mean age 74 years; range 59 to 86 years) treated with the Endurant stent grafts between January 2009 and February 2010, the outcomes of technical success, endoleak and perioperative mortality rates were documented. These patients were treated with indications of infrarenal aneurysms (n=10), penetrating atherosclerotic ulcer (n=1) or ruptured iliac aneurysm (n=1). These results were compared with 23 patiens (2 females, 21 males; mean age 72; years; range 61 to 82 years) whose abdominal aortic aneurysms were treated with the Talent endografts between November 1994 and January 2009.

Results: Technical success was achieved in the 12 patients with the Endurant stent grafts. In nine of these 12 patients aortobiiliac tube grafts and in the remaning three patients tube grafts were used. No endoleak was detected at the early postoperative control computed tomography angiography. Aneurysm diameters were 51-72 mm, aneurysm necks were 10-20 mm and aneurysms neck angulations were measured as 0-90 degrees. Neither aneurysmal nor conversion to open repair-related deaths have been observed over 30 days. In the Talent group, the aneurysm diameters were 50-80 mm, aneurysm necks were 8-25 mm and aneursym angulations were measured as 0-60 degrees. In the Talent group four aortouniiliac and 19 aortobiiliac grafts were used. In these 23 patients two type 1 leaks were treated with a proximal cuff and two type 2 leaks disappeared during the follow-up.

Conclusion: The newly developed Endurant stent graft with a low profile can be delivered and deployed in angulated necks and stenotic iliac vessels. However, it should be assessed with long-term follow-ups in terms of graft migration and patency.
