Purpose : To identify risk factors for late-occurring @entity732 following multibranched @entity2334 . Method : Out of 120 @entity1 who underwent multibranched @entity439 repair between September 2005 and May 2013, 100 (78 @entity1 ; mean age 72.4  7.4 years) met the criteria for inclusion in the current retrospective analysis. Demographic data were gleaned from a prospectively maintained database. Mean @entity439 diameter was 66.7  11.7 mm. Multiplanar reconstructions of postoperative computed tomographic angiography were used to measure 6 parameters of renal branch morphology. Results : All 100 @entity1 had undergone successful placement of multibranched aortic stent-grafts with a total of 95 celiac branches, 100 @entity6029 ( @entity6029 ) branches, and 187 renal branches. During a mean follow-up of 25.6 months, there were no stent @entity174 or stent separations, no @entity432 , and only 2 (2.1%) celiac artery occlusions, neither of which required reintervention. In contrast, there were 18 (9.6%) @entity8 in 16 @entity1 , all @entity1 (p=0.02). @entity1 with @entity8 were significantly more likely to have a history of @entity583 (p=0.004). The mean renal artery length was significantly greater in the occlusion group compared to the non-occlusion group (47.5  13.6 vs. 39.4  14.2, p=0.03). No other aspect of branch morphology was significantly different between the occlusion and non-occlusion groups. Conclusion : @entity8 was by far the commonest late failure mode after multibranched @entity439 repair. The current study provides no basis for a change in @entity1 selection or stent-graft design, only a change in the components used to construct renal branches. It is too early to tell the effect this will have.
