OBJECTIVE: To evaluate short and long-term outcomes of total arch replacement using the trifurcated graft technique, antegrade cerebral perfusion and deep hypothermic circulatory arrest.

METHODS: We reviewed 77 patients (42 males, 54%) who underwent total arch replacement with antegrade cerebral perfusion and deep hypothermia circulatory arrest from January 2005 to December 2017. Deep hypothermic circulatory arrest was achieved between 18-22 C. All patients had antegrade cerebral perfusion either immediately after circulatory arrest (perfusion first) or after completion of the distal anastomosis (surgery first). Trifurcation grafts were utilized in 44 (57%) patients and bifurcation grafts were utilized in 33 (43%) patients. Indications for surgical repair included degenerative aneurysms in thirty (38%) patients, chronic dissection in 25 (32%), acute dissection in 15 (19%) and atherosclerotic aneurysms in 10 (13%). Thirty-one (40%) patients had undergone previous cardiac surgery.

RESULTS: Hospital mortality was 5% (4 patients). Postoperative stroke and transient ischemic attack occurred in 3 (4%) patients. Renal insufficiency occurred in 10 (13%) patients. Mean circulatory arrest time was 18 15 minutes and mean antegrade cerebral perfusion time was 60 21 minutes. The median duration of intensive care and hospital length of stay was 6 and 15 days respectively. Ninety percent of patients were alive at 1 year, 76% at 5 years and 68% at 10 years.

CONCLUSIONS: In the era of hybrid and endovascular repair, open total arch replacement utilizing the trifurcated graft technique, antegrade cerebral perfusion and deep hypothermic circulatory arrest offers outstanding short-term outcomes in addition to good long-term survival rates (Figure 1).
