[Doppler sonography after extra-intracranial anastomosis operations].
Extra-intracranial anastomosis are thought to improve the regional cerebral blood flow in patients with a stenosis or occlusion of the carotid system and prevent the later occurrence of ischemic cerebral diseases. Doppler-sonography has been used for a follow up of the effectiveness of the surgical procedure. We believe that minor hemodynamic improvements after surgery cannot be detected by Doppler-sonography. However this method is very useful in demonstrating the patency of the anastomosis.
