Where to Fenestrate in Aortic Dissection Type B? An Ex Vivo Study.

Background: Fenestration is a minimally invasive alternative for the treatment of acute symptomatic aortic dissections because it may quickly decrease the pressure gradient of the false lumen. It remains unclear where the optimal location of these fenestrations should be chosen. The purpose of this study was to study false lumen volume (FLV) after different fenestration strategies in porcine ex vivo models of aortic type B dissection.
