Mortality after acute type A aortic dissection (AAAD) is some of the highest in cardiac surgery. The dissected tissues are fragile and provide a thin layer for performing the aortic anastomoses. We study the influence of a mixture of bovine serum albumin (45%, w/v) and glutaraldehyde (10%, w/v) in a 4:1 ratio on bleeding and early results ([30 days) after AAAD repair.
