Pseudoaneurysm of the ascending aorta

ABSTRACT

A 37 year-old woman underwent aortic and mitral valve replacement and 3 months later developed a pseudoaneurysm from the anterior aspect of the proximal ascending aorta [AA]. The pseudoaneurysm was approached through a redo-median sternotomy on cardiopulmonary bypass [CPB], moderate hypothermia, and repaired successfully using autologous pericardium The standard approach to such pseudo aneurysm is a CBP and hypothermic circulatory arrest prior to midsternotomy, and repair or replacement of the and but when a pseudo aneurysm arises from a narrow ostiurn on the anterior aspect of the AA, as in this case, it can be repaired under CPB with moderate hypothermia
