Aim. To evaluate single center results with selective use of the Gore Excluder stent-graft for elective abdominal aortic aneurysm repair.
Methods. Retrospective analysis of a prospective data base. Primary endpoints were technical success, all-cause and aneurysm-related mortality and aneurysm rupture. Secondary endpoints were late complications including migration, endoleak, aneurysm growth, limb occlusion, and re-intervention.
Results. The Gore Excluder stent-graft was used in 92 elective cases, mainly in cases with difficult iliac anatomy. There were 81 (88%) male patients. Mean age was 70.4±7.5 (range, 53-87). Primary assisted technical success rate was 98.9% (91/92 patients). Thirty-day mortality was 0%. Median follow-up was 35.7 months (range, 2-99). Overall survival was 95.2±2.4% at 1 year, 89.2±3.7% at 2 years, 83.9±4.5% at 3 years and 70.2±6.8% at 5 years. During follow-up there were 3 (3.3%) Type I endoleaks and 20 (21.7%) Type II endoleaks. Proximal migration of more than 5 mm without endoleak occurred in two patients. In total 13 re-interventions were performed in 12 (13%) patients. No graft limb occlusion occurred. No aneurysm ruptured during follow-up.
Conclusion. Selective use of the Gore Excluder demonstrates excellent short- and long-term results. Despite being used in challenging iliac anatomy no graft limbs occluded.
