Key result
A simplified delivery technique for the frozen elephant trunk procedure allows the distal suture to be performed on a perfused aorta, reducing circulatory arrest time to just a few minutes.
Why the study?
A delivery technique for the frozen elephant trunk procedure was needed to reduce circulatory arrest time during hybrid aortic arch surgery.

A modified frozen elephant trunk delivery technique reduces circulatory arrest time to a few minutes, potentially improving safety and outcomes in aortic arch surgery.
A simplified delivery technique for the frozen elephant trunk procedure allows the distal suture to be performed on a perfused and loaded aorta in moderate hypothermia-or even normothermia-reducing circulatory arrest time to just a few minutes. Two surgical sealing tourniquets are placed around the aortic arch, usually between the brachiocephalic trunk (BCT) and the left common carotid artery and the aorta is cross-clamped and cardioplegia started. Once in mild hypothermia, the BCT is disconnected and circulatory arrest is initiated while cerebral perfusion is maintained. This modified technique can be used in all pathologies, including dissections.
