Abstract:
Blood flow in 49 patients suffering from stenosing lesions of the supraaortic trunks was measured using an ultrasonic volume flow metre (VFM) before and after operation. Results showed a statistically significant increase in the values of carotid flow, after operation. This non-invasive quantitative determination of blood flow provides the surgeon with often essential information for correct operation and subsequent follow-up.
