Pseudoaneurysm of ascending aorta combined with aortic valve infective endocarditis after cardiac operations for congenital ventricular septal defect.

摘要

We read with great interest the article of Emaminia and colleagues1 and congratulate them for their successful repair of an iatrogenic pseudoaneur-ysm of the ascending aorta. Their strategy to safely reopen the sternum is to drain the blood into the oxygenator reservoir for 1 to 2 minutes to have an empty, relatively collapsed heart and aorta without establishment of femoro-femoral bypass. We want to know how much blood should be drained and how to maintain hemodynamics during the procedures. Fortunately, the pseudoa-neurysm was located at the back of ascending aorta. Otherwise, how would the hemodynamics problem be dealt with if the reentry of the sternum was not uneventful?
