[Ultrasonic flow metering in the diagnosis of occlusive lesions of the extracranial portions of the carotid arteries].
The paper is concerned with the results of a new method of investigation--ultrasound fluometry, based on the Doppler effect. This method was applied in patients with atherosclerotic lesions of the carotid arteries. The authors studied 57 patients in the acute stage of the ischemic stroke and 32 patients with chronic insufficiency of the brain blood supply. The report describes the principle of the ultrasound debitmeter action. Some features of a total and subtotal occlusion and stenosis of the extracranial part of the carotid artery and the features of collateral circulation were detected. The authors point of comparable data of ultrasound fluometry and contrast angiography, and the valuability of ultrasound fluometry for the determination of indications to angiographic studies. The advantage of the new methods is the possibility of its use in outpatient practice and in hospitals for evaluating the effectiveness of the used treatment as well as for observing cerebral hemodynamics during the postoperative period.
