Why the study?
Does routine cannulation through a Dacron graft improve myocardial protection and avoid deleterious effects of retrograde blood flow compared to femoral cannulation in surgery for acute dissection of the ascending aorta?

Cannulation through a Dacron graft during surgery for acute ascending aortic dissection may offer better myocardial protection and avoid the risks of retrograde flow associated with femoral cannulation.

May support antegrade true-lumen perfusion in acute aortic dissection surgery; leaves open comparative outcomes versus femoral cannulation.
In surgery of the acute dissection of the ascending aorta, a technique is described for routine cannulation through a Dacron graft in order to produce antegrade flow in the true aortic lumen and higher pressures than in the false lumen. This is a useful method to avoid the deleterious effects of the retrograde blood flow through the false lumen, when femoral cannulation is used, as well as to improve the myocardial protection by reperfusing the myocardium while the graft distal end anastomosis is carried out.
