The ultrasonographic confirmation of the role of external carotid artery in blood supply of ischemic lesion in the big cerebral hemisphere

Using intraoperative monitoring of the blood flow linear speed in a. cerebralis media while total a. carotis interna occlusion in 10 patients the authors have concluded, that the degree of blood flow compensation in a. cerebralis media depends not only on collateral compensation possibilities by the contralateral side and rate of it inclusion, but largely-on a. carotis externa possibility on the lesion side.
