Abstract
Objectives: Consensus regarding initial cannulation site for acute type A dissection repair is lacking. Objectives were to review our experience with systematic initial axillary artery cannulation, characterize patients on the basis of cannulation site, and assess outcomes. Methods: From January 2000 to January 2017, 775 patients underwent emergency acute type A dissection repair. Initial axillary cannulation was performed in 617 (80%), femoral in 93 (12%), and central in 65 (8.4%). In-hospital mortality and stroke risk factors were identified using logistic regression. Results: Reasons for selecting initial central or femoral instead of axillary cannulation included unsuitable axillary anatomy (n = 67; 42%), surgeon preference (n = 38; 24%), hemodynamic instability (n = 34; 22%), and preexisting cannulation (n = 19; 12%). Cannulation site was shifted or added intraoperatively in 82 (11%), with initial cannulation site being axillary (n = 23 of 617; 3.7%), central (6 of 65; 9.2%), or femoral (n = 53 of 93; 57%), for surgeon preference (n = 60; 73%), high flow resistance (n = 13; 16%), increased aortic false lumen flow (n = 6; 7.3%), and other (n = 3; 3.7%). In-hospital mortality was 8.6% (n = 67; lowest for axillary, 7.3% [P =.02]) and stroke 8.3% (n = 64). Hemodynamic instability (odds ratio [OR], 7.6; 95% confidence interval [CI], 4.2-14), limb ischemia (OR, 3.7; 95% CI, 1.5-9.3), stroke (OR, 5.5; 95% CI, 2.2-14), and aortic regurgitation (OR, 2.2; 95% CI, 1.2-4.2) at presentation were risk factors for mortality and central cannulation site (OR, 2.3; 95% CI, 1.05-5.1) and aortic stenosis (OR, 2.4; 95% CI, 1.2-4.6) for stroke. Conclusions: Systematic initial axillary cannulation for acute type A dissection repair is safe and effective and can be tailored to patients' specific needs. With this strategy, comparable outcomes are observed among cannulation sites and are largely determined according to patient presentation rather than cannulation site.
