Ascending aortic pseudoaneurysm

摘要

Ascending aorticpseudoaneurysms are rare entities that can occur secondary to trauma, infection, connective tissue disorders, vasculitis, or as a complication of cardiac surgery. The most common predisposing cause is aortic root surgery followed by coronary artery bypass graft surgery; they are well-known complications after any cardiac surgery although ascending aortic pseudoaneurysms occur in less than 0.5% of all cardiac surgical cases.
