[A preliminary evaluation on transcranial Dopplor ultrasonic scanning for differentiation of symptoms and signs in patients with ganyang shangkangzheng].

Intracranial main artery of Ganyang Shangkangzheng and its related syndrome were determined by Transcranial Doppler (TCD) Ultrasonography. The results showed that the blood flow speed in the mid-cerebral artery of 32 cases with Ganyang Shangkangzheng was obviously higher than that of the healthy group, Ganhuo Shangyan group and Gan-shenyinxu group, similar change was found in three kinds of parameters in the blood flow speed. Therefore, the results suggest that TCD in determinating the blood flow speed of middle cerebral artery can be thought as one of the diagnostic assays in differentiation of symptom and sign of Ganyang Shangkangzheng.
