Methods: 96 cases in this series paid their visit with headache during 1998.3-1999.3. Among them, 41 cases were male and 55 female, ranging in age from 18 to 72 years, with an average of 42 years. Bilateral MCA, ACA and PCA were tested through right and left temple, bilateral VA and BA by 2MHz Pulse sound of Doppler ultrasound apparatus (TC-7770 type apparatus, EME Co. German). The blood flow rate, frequency spectrum, audio frequency and pulse index of above arteries were recorded. Evaluation of TCD was in reference to the normal range of the book—TCD and Clinical practice edited by Xu Shaoyan. The blood flow rate was considered faster when the value was 15cm/s higher than upper limit of normal value and considered slow when the value was 5-10cm/s lower than lower limit of normal value. The difference of bilateral blood flow rate was more than 15cm/s, considered asymmetry. Hyperactivity of the Liver-Yang type (37 cases): manifested by headache, dizziness, flushed face, bitter taste, yellow tongue coating, taut pulse; Deficiency of both qi and blood type (34 cases): manifested by continuous headache, dim complexion, severe palpitation, fatigue, pale tongue with thin coating, thready pulse; Accumulation of blood stasis in the channels type (25 cases): manifested by stabbing headache, fixed location, darken tongue, thready and uneven pulse.

 

Results: The characteristics of TCD of Hyperactivity of the Liver-Yang type (37 cases) were high resistance frequency spectrum of the blood flow, noise murmur of audio frequency high pulse index, and fastened blood flow. These indicated the changes of spastic stricture in the cerebral angry. The characteristics of TCD of deficiency of both qi and blood type (34 cases) were elasticity attenuation of cerebral arteries frequency spectrum, attenuation of audio frequency, pulse index reduced and slow blood flow. These showed ischemic changes of blood flow hyper fusion. The characteristics of TCD of Accumulation of blood stasis in the channels type (25 cases) were obvious asymmetry of bilateral blood flow, which was more rapid on the affected side. This showed hypertension of the affected side.

 

Conclusion: Integration of TCD testing and TCM syndrome differentiation contributed to the treatment of TCM according to cerebral-vascular hemodynamics of different type of headache. It provided an objective index for TCM Syndrome Differentiation.
