BACKGROUND: The purpose of this study was to determine durability and need for reinterventions after endovascular stent graft placement in @entity731 involving the descending aorta. METHODS: We performed a prospective follow-up analysis of a consecutive series of 79 @entity1 undergoing endovascular stent graft placement due to @entity731 involving the descending aorta between 1996 and 2006. Acute aortic syndromes were excluded from this analysis. Mean follow-up was 42 months (range, 1 to 108 months). Data were collected for in-hospital mortality, occurrence of early and late endoleaks, reintervention due to early and late endoleaks, and survival. RESULTS: In-hospital mortality was 6.3% (n = 5). Two of these @entity1 underwent emergent treatment. Early type I and III endoleaks were observed in 29% of @entity1 (n = 23). The assisted primary @entity1070 rate was 11%. Late type I or III endoleaks occurred in 21% (n = 17). At 1, 3, and 5 years, overall actuarial survival was 96%, 86%, and 69%, and event-free survival was 90%, 82%, and 65%, respectively. Cox proportional hazard analysis revealed that a short proximal landing zone and a high number of stent grafts used were independent risk factors for early and late @entity1070 formation. Late @entity1070 formation was an independent predictor of survival. CONCLUSIONS: Endovascular stent graft placement in @entity731 involving the descending aorta has satisfactory durability. An extensive landing zone is a prerequisite of early and late success. Further clinical investigations are warranted to evaluate long-term durability of this attractive treatment modality.
