OBJECTIVE: The aim of this study was to evaluate the impact of intercostal and lumbar segmental arteries (SAs) detectable on computed tomography angiography (CTA) on the risk of @entity2759 ( @entity2759 ) in @entity1 undergoing single-step or two-staged branched @entity439 repair (BEVAR). METHODS: A retrospective analysis of @entity1 treated with branched stent grafts for @entity2334 at a single institution from January 2009 to June 2015 was performed. Data including preoperative comorbidities, perioperative and @entity439 -related parameters, presence and type of endoleak, and rate of severe @entity2759 at discharge or 30  days after the procedure were collected. Preoperative and postoperative contrast-enhanced CTA images were semiquantitatively analyzed by two independent investigators, and the number of visible SAs in the stented aorta before and after BEVAR was evaluated to find a possible correlation with severe @entity2759 . RESULTS: Seventy-seven @entity1 were treated for @entity2334 with BEVAR (47 @entity1 ; mean age, 71.0  years), 40 (51.9%) of them with temporary @entity439 sac perfusion (TASP; open branch/TASP group) and 37 without (single-step group). The groups were comparable regarding parameters related to the @entity1 , @entity439 type, and endovascular procedure. Severe @entity2759 or @entity451 was observed in 10 @entity1 (12.3%), and @entity2759 was lower in the open branch/TASP group (2/40) compared with the single-step group (8/37; P  = .032). The number of visible SAs in the intentionally overstented aortic segment was significantly reduced on postoperative CTA (10.0 vs 15.57 SAs; P  < .001) in comparison to preoperative CTA imaging, with similar results in the open branch/TASP group (9.48 vs 15.83 SAs) and the single-step group (10.57 vs 15.30 SAs; P  < .001 for both groups). Within the open branch/TASP group, more visible SAs were detected during the TASP interval in comparison to postoperative CTA after side branch completion (12.93 vs 9.48 SAs; P  <  .001). Receiver operating characteristic curve analysis in the single-step group revealed a cutoff point of 15 SAs on preoperative CTA with correlation to severe @entity2759 (P  = .006). In the high-risk subgroup of @entity1 with 15 or more overstented SAs during BEVAR, staged open branch/TASP procedures again reduced the risk of @entity2759 in comparison to the single-step @entity1 (1/20 vs 8/22; P  = .008). CONCLUSIONS: More spinal arteries are visible during the TASP interval, supporting the open branch and TASP concept  with a reduction of severe @entity2759 during BEVAR. An intentional coverage of more than 15 SAs is related to an increased risk of  @entity2759 , and the rate of @entity451 was reduced after staged BEVAR with open branch/TASP in these high-risk @entity1 .
