- W2926445263 abstract "Background Perioperative stroke is a major complication after debranching thoracic endovascular aortic repair (TEVAR), with a reported incidence of 7.0–26.9%. Subsequent functional recovery is difficult in most cases. This study was performed to evaluate the efficacy of mini-cardiopulmonary bypass (mini-CPB) support in debranching TEVAR to prevent perioperative stroke. Methods From December 2010 to July 2017, 32 patients with a shaggy aorta or intimal irregularity in the aortic arch identified on preoperative computed tomography underwent debranching TEVAR. Nineteen patients underwent debranching TEVAR without mini-CPB, and 13 patients underwent debranching TEVAR with a mini-CPB support. Mini-CPB support had been used in November 2014 to treat perioperative stroke, which had occurred in 8 (42%) patients at that time. The form of the debranching arch vessels was not changed; bypass from the right axillary artery to the left axillary artery was performed for one debranching, and bypass from the right axillary artery to the left common carotid artery and left axillary artery was performed for two debranchings. After establishment of mini-CPB support through this debranching graft and right femoral vein cannulation, all endovascular manipulations were initiated. The left subclavian artery was occluded with a plug at the end of the procedure. Results The proximal landing zones of the endoprosthesis were as follows: zone 0 in 9 patients, zone 1 in 5 patients, and zone 2 in 5 patients in the no-CPB era and zone 1 in 3 patients and zone 2 in 10 patients in the CPB era. The mean mini-CPB support period was 51 minutes. Postoperative respiratory support and hospitalization were not prolonged with mini-CPB support. The incidence of perioperative stroke was 42% in the no-CPB era and 8% in the CPB era. No operative mortality was observed in the CPB era, although 5 (26%) patients died in the no-CPB era. The cause of operative mortality in the no-CPB era was perioperative stroke in 4 patients and acute myocardial infarction in 1 patient. No significant difference in the cumulative survival rate was found between patients with and without mini-CPB support. Conclusions Our mini-CPB system may have the potential to prevent perioperative stroke during debranching TEVAR for treatment of aortic arch pathologies.
