Much of the previous robust analyses of the results associated with transcarotid revascularization (TCAR) derives from industry-sponsored trials or the Vascular Quality Initiative (VQI). This investigation was performed to identify preoperative predictors of 30-day stroke and death using institutional databases.A retrospective analysis was performed of carotid revascularization databases created at two high-volume TCAR centers and maintained independently of the VQI carotid module between December 2015 and December 2021. The primary outcome of interest was a composite of perioperative (30-day) stroke and death. Univariate regression analyses, followed by multivariate regression analyses, were performed to identify potential predictors of adverse events.During the study period, 750 TCAR procedures were performed at our combined health systems, resulting in 24 (3.2%) individuals who experienced either stroke and/or death in the perioperative period. Of these, we observed nine (1.2%) mortality events and 18 (2.4%) strokes. On univariate analysis, candidate protectors of stroke/death were found to be coronary artery disease (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.18-1.01; P = 0.05) and protamine reversal (0.51; 0.21-1.21; P = 0.15). Candidate predictors of the primary outcome were anticoagulant usage (3.03; 1.26-7.24; P = 0.01), postprocedural debris in the filter (2.30; 0.97-5.43; P = 0.06), symptomatic carotid lesion (2.03; 0.90-4.50), and cardiac arrhythmia (1.98; 0.80-4.03; P = 0.14). On multivariate analysis, two predictors remained, cardiac arrhythmia (4.21; 1.10-16.16; P = 0.04) and symptomatic carotid lesion (14.49; 1.80-116.94; P = 0.01).A symptomatic carotid lesion, and to a lesser extent cardiac arrhythmia, are strong predictors of 30-day stroke/death after TCAR. Surgeons should be cognizant of the increased risk of adverse events in the perioperative period in these patients. |
