OBJECTIVES: Iliac branch grafts (IBGs) are a validated option for the treatment of @entity1029 preserving @entity2998 ( @entity2998 ) flow. @entity2998 @entity439 (IIAA) is a relative contraindication to IBG placement. The goal of this study was to review experience in managing @entity1029 with concomitant IIAAs with extension of the @entity2998 branch stent graft into the superior gluteal artery (SGA). METHODS: This retrospective study between May 2009 and November 2014 includes consecutive @entity1 who underwent placement of an IBG (Cook, Bloomington, IN, USA) with extension of the internal iliac component of the branch stent graft into the SGA because of @entity1029 (>15  mm). The stent grafts used were Viabahn (Gore, Karlsruhe, Germany), Fluency (Bard, Flagstaff, AZ, USA), or iCast (Atrium, Hudson, NH, USA) proximally. Imaging follow up was with computed tomography angiography (CTA) within 30 days of device insertion and then annually. RESULTS: The procedure was performed on 15 @entity1 with a mean age of 76.8 years (SD 6.1 years). Twenty IIAAs were treated with a mean @entity2998 and common iliac artery (CIA) diameter of 33  mm (SD 13  mm) and 35  mm (SD 11  mm) respectively. Technical success rate was 100%. One @entity1 who underwent simultaneous IBG and three vessel fenestrated @entity439 repair died of @entity5327 2 days after the procedure. Mean imaging follow up with CTA was 18.3 months (SD 15.1 months). Primary patency of the SGA stent grafts was 100%. There was one case of @entity1070 . All @entity1 were free from buttock claudication at follow up (mean: 19.7 months). Two @entity1 who had @entity2998 embolization contralateral to the IBG placement suffered from unilateral lower limb monoparesis. CONCLUSIONS: Extension of the internal iliac component of IBGs into the SGA for distal seal is feasible and safe in the endovascular treatment of @entity1029 with concomitant IIAs. Long-term results are needed to further validate this technique.
