Total arch replacement using a 4-branched vascular graft without circulatory arrest allows arch reconstruction with early rewarming and reperfusion to minimize organ ischemia.
Describes a surgical technique for total arch replacement using a 4-branched vascular graft without circulatory arrest to minimize organ ischemia.
May reduce organ ischemia in arch replacement; leaves open need for comparative trials before adoption.
The technical essentials of the procedure include femoral artery cannulation, selective antegrade cerebral perfusion for brain protection, total arch replacement with a 4-branched vascular graft, implantation of the special open stented graft into the descending aorta, moderate hypothermic balloon occluding descending aorta at 25℃. This technique allows arch reconstruction to be debranched first and upper part of the body is perfused via the 4-branched vascular graft, ensuring antegrade true lumen cerebral perfusion rapidly secured, the descending aorta is arrested by balloon occluding and early rewarming and reperfusion after distal anastomosis to minimize organs ischemia.

Long et al. (2019) studied this question. Total arch replacement using a 4-branched vascular graft without circulatory arrest was evaluated. Total arch replacement using a 4-branched vascular graft without circulatory arrest allows arch reconstruction with early rewarming and reperfusion to minimize organ ischemia.
