XXXX Repair of @entity439 with an Iliac Side-branched Stent graft: Studying the Morphological Applicability of the Cook Device.

@entity1 @entity323 @entity439 @entity1029
OBJECTIVE/BACKGROUND: @entity439 ( @entity439 ) repair of an aortic @entity439 extending to the iliac artery remains a challenge. Interventional occlusion of the internal iliac artery (IIA) intending to create a distal landing zone in the external iliac artery is a common approach with inherent morbidity (e.g., buttock claudication, @entity323 ). Alternatively, iliac side-branched stent grafts can maintain pelvic blood supply, but the applicability is limited. The objective was to investigate the morphological applicability of the Cook Zenith branched graft (ZBIS) among @entity1 with aorto-iliac or isolated @entity1029 . METHODS: This was a retrospective single centre analysis of 66 @entity1 (60 @entity1 ; median age 74 years, range 53-90 years) undergoing repair of aorto- @entity1029 (open repair, IIA occlusion prior to @entity439 and ZBIS) between January 2008 and December 2012. All available computed tomography angiograms with post-processing imaging were compared with the criteria for morphological applicability to (i) the manufacturer's instruction for use (IFU), and (ii) to criteria published in the literature, as well as (iii) to the institutional protocol. RESULTS: In 66 @entity1 , 88 targeted @entity1029 were studied. Of these, 36/88 (40.9%) were compliant with the manufacturer's IFU, 35/88 (39.8%) were compliant with the published criteria, and 51/88 (58.0%) were compliant with the in house protocol. The most common morphological exclusion criterion was an @entity1029 . CONCLUSION: In the present cohort with aorto-iliac @entity439 , a maximum of 58% could have been treated with an iliac side branch based on the current experience. In particular, an @entity1029 seems to be a limiting factor for the use of the iliac side-branched stent graft.
