RESULTS
Of 202 patients, operative mortality was 6% and the incidence of postoperative stroke was 12% (n=25). Brachiocephalic artery dissection was associated with higher risk of stroke (odds ratio, 3.89, 95%CI 1.104-13.780; P= .035) having no relation with the presence or absence of left common carotid artery dissection. Preoperative malperfusion syndrome, circulatory arrest time, isolated cerebral perfusion time, repair technique (total arch replacement), and femoral artery perfusion alone were not related to the incident rate of postoperative stroke. Stroke occurred in both hemispheres, regardless of the laterality of carotid artery dissection.
