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.
