BACKGROUND: Whereas carotid endarterectomy (CEA) remains the "gold standard" treatment, given its low complication rate, @entity2998 ( @entity2998 ) has emerged as a valid alternative in @entity1 with prohibitive surgical risks. However, the application of @entity2998 has been scrutinized, given its increased perioperative risk in comparison to CEA. Operators follow general guidelines in intraoperative techniques in @entity2998 . However, few of those are evidence based. We believe that a specific outcome-driven examination of the effect of pre- and poststent deployment ballooning is warranted. The objective of this study was to analyze the effect of prestent ballooning (pre-SB) and poststent ballooning (post-SB) on @entity308 ( @entity308 ) and perioperative @entity64 or @entity204 . METHODS: We performed a retrospective analysis of all @entity1 who had @entity2998 between 2005 and 2014 in the Vascular Quality Initiative database. Logistic regression analyses of the effect of different pre-SB and post-SB combinations on @entity308 and the 30-day @entity64 and @entity204 rate were performed. We excluded @entity1 who had no protection device, those with isolated common carotid artery lesions, and those who had no ballooning at all. The models controlled for @entity1 age, gender, comorbidities, smoking status, symptomatic status, history of previous ipsilateral CEA, preoperative medications, and @entity850 . RESULTS: A total of 3772 @entity1 who underwent @entity2998 were included for analysis. Average age of @entity1 was 69.8    9.6 years, with 63% being male. The overall perioperative @entity64 and @entity204 rate was 3.0%. Compared with pre-SB only technique, the combined pre-SB and post-SB technique had a 2.1-fold increase in @entity308 (odds ratio, 2.13; 95% confidence interval, 1.51-3.01; P < .001) and 2.4-fold increase in perioperative @entity64 and @entity204 rate (odds ratio, 2.37; 95% confidence interval, 1.01-5.62; P < .050). CONCLUSIONS: Compared with pre-SB alone, the use of post-SB increases the chances of perioperative @entity308 and @entity64 and @entity204 rate in @entity1 undergoing @entity2998 . Post-SB should be used only in those cases with severe @entity850 .

Poststent ballooning is associated with increased periprocedural XXXX and @entity204 rate in @entity2998 .
