    Technique and rationale for branch-first total aortic arch repair
    Kim, M ; Matalanis, G (ELSEVIER, 2020-12-01)
    OBJECTIVE: Our objective was to describe the technique and rationale for branch-first total aortic arch repair. METHODS: Branch-first total aortic arch repair involves serial clamping, reconstruction, and reperfusion of each of the arch branches using a specially designed trifurcation graft with a side port. During this sequence, perfusion to the heart and distal organs are preserved and continuous antegrade cerebral perfusion is permitted via the trifurcation graft. The diseased aorta is excised and replaced with a Dacron graft (W.L. Gore and Associates, Newark, Del) with a perfusion side port. The trifurcation graft is anastomosed to the new proximal ascending aorta. RESULTS: The branch-first technique permits total aortic arch repair without global cerebral circulatory arrest and excessive hypothermia. It shortens distal organ and cardiac ischemic time, and reduces the opportunity for air and particulate embolization during aortic repair. CONCLUSIONS: Branch-first total aortic arch repair allows continuous antegrade cerebral perfusion and shortens distal organ and cardiac ischemic time, with unobstructed access to the full extent of the diseased aortic arch.
