[Clinical evaluation of Doppler ultrasonic angiography]

The diagnosis of carotid surgery is based on angiography. 1607 Doppler cases of extracranial carotid Doppler ultrasonic angiography were examined. Among them, 1527 had remote cerebral stroke and 285 had carotid endarterectomy. The results indicated that the group of carotid endarterectomy conformed to Doppler ultresonic angiograph of preoperation and were consistent with 10 positive and 10 negative cases of random sampling. The method has advantages of easy operation, time-saving, low expenses, no complication and reliable diagnosis to use Doppler ultrasonic angiograph in carotid surgery. It was worth spreading in non-invasive arterial morphology and hemodynamics.
