Background: The effect of the surgical sealant AQUABRID on outcomes after acute aortic dissection repair has not been evaluated. The objective of this study was to examine whether the use of AQUABRID affects the volume of intraoperative blood transfusion or operative time in patients undergoing emergency surgery to repair acute aortic dissection., Methods: A multicenter retrospective cohort study from January 2007 to December 2021. A total of 399 patients underwent emergency acute aortic dissection repair. Propensity score matching was used to adjust for the type of surgery and other patient characteristics., Results: A total of 387 of the eligible 399 patients were included in this study and propensity score matching yielded 94 patients for whom characteristics were not significantly different between the two groups. The type of surgery was exactly matched (ascending aorta replacement: 19 [40%]; partial arch replacement: 13 [28%]; total arch replacement: 15 [32%] in each group). Within the matched cohort, there was a statistically significant difference in the volume of intraoperative blood transfusion. (AQUABRID vs. control: 34 [26-38] vs. 50 [38-60] U in Japan, p = .03). Operating time was significantly shorter in the AQUABRID group (total operation: mean ± SD, 343 ± 92 vs. 402 ± 161 min, p = .03; reconstruction for arch vessels: 29 ± 17 vs. 56 ± 22, p < .01). The rate of postoperative complications was comparable in the two groups. Failure to use AQUABRID was a significant predictor of the need for massive transfusion (>40 U) (odds ratio: 7.20; 95% confidence interval: 2.56-20.23; p < .01)., Conclusions: The use of AQUABRID during emergency acute aortic dissection repair significantly decreased the volume of intraoperative blood transfusion and the duration of surgery., (© 2022 Wiley Periodicals LLC.)

Objective: This study evaluated the efficacy of the provisional extension to induce complete attachment (PETTICOAT) technique for type B and postoperative residual type B aortic dissections compared with the conventional thoracic endovascular aortic repair (TEVAR) technique., Methods: In this retrospective study, we compared sequential aortic morphologic changes in consecutive patients with type B and postoperative residual type B aortic dissections treated with the PETTICOAT technique between January 2016 and December 2017 with patients treated with the conventional TEVAR between January 2013 and December 2015. Outcomes included aortic remodeling and aorta-related adverse events for 2 years postoperatively., Results: Forty-eight patients were included in this study (24 in the PETTICOAT group, 24 patients in the conventional TEVAR group). Although both groups showed aortic remodeling in the descending thoracic aorta, the PETTICOAT group developed significantly better aortic remodeling in the abdominal aorta compared with the conventional TEVAR group during the observation period. The PETTICOAT group had significantly fewer aorta-related adverse events compared with the conventional TEVAR group (8% vs 54%; P < .001). Aorta-related adverse events more commonly occurred in the poor remodeling group compared with in the good remodeling group (P = .001; hazard ratio, 8.32; 95% confidence interval, 2.26-30.64)., Conclusions: This study suggests that the PETTICOAT technique for aortic dissection may promote aortic remodeling and decrease the incidence of aorta-related adverse events. Additional studies are required to confirm these preliminary findings., (Copyright © 2020 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)
