Simple classification of carotid bifurcation: is it possible to predict twisted carotid artery during carotid endarterectomy?

Twisted carotid bifurcations were observed during operation in 10 % in type 2 and 100 % in type 3. CEA of twisted carotid bifurcations can be performed safely with or without correction of the carotid position. AP view of cerebral angiography could be useful for preoperative evaluation.
