Abstract

Arterial cannulation in acute DeBakey type I dissection can be difficult. Moreover, the residual dissected aorta is susceptible to further adverse events in the future. Implanting a stent-graft into the descending aorta during the initial dissection repair ('frozen elephant trunk') has been demonstrated to promote favourable aortic remodelling, mitigating some of these longer-term complications. We describe a technique for cannulation of the ascending aorta in acute dissection that facilitates expeditious antegrade deployment of a frozen elephant trunk.

Keywords: Aortic dissection; Cannulation; Elephant trunk; Stent-graft.
