  • Title: [Reliability of the results of the ultrasonic hemodynamic recording (Doppler effect) in the diagnosis of cerebral ishemic ischemia of carotid origin].

    Abstract:
    The Doppler ultrasound diagnosis of carotid artery stenosis (asymetrical systolic and diastolic flows; elevated resistance index: ratio of flow pulse amplitude to systolic and diastolic values; flow reversal in the ophtalmic artery) is compared, in 52 patients, to the clinical, angiographic (40 patients) an surgical findings and to the peroperative measure of intra-arterial pressure and flow (30 patients). Its reliability is proved as a guide for angiographic exploration and for postoperative watching, but it is restricted to great vessels (cervical carotid artery) and is unable to detect ulcerated plate without stenosis.
