Axillary Versus Femoral Arterial Cannulation in Acute Type A Dissection: International Multicenter Data

A cohort of 2145 patients from the International Registry of Acute Aortic Dissection were compared according to whether they had axillary (1106 [52 percent]) or femoral (1039 [48 percent]) arterial cannulation. Patients with axillary cannulation had more total arch (15 percent versus 11 percent, P < .02) and valve-sparing root replacements (22 percent versus 12 percent, P < .001), but in-hospital mortality (15 percent versus 14 percent, respectively; P = .7) and stroke rates were similar compared with femoral cannulation.
