摘要
目的 :测定腔隙性脑梗死颅内血管血流动力参数。方法 :采用经颅多谱勒 (TCD)对 30 0例经CT或MRI确诊的腔隙性脑梗死患者的颅内各主要动脉进行测定。结果 :30 0例腔隙性脑梗死TCD表现 :血流速度缓慢、供血不足 6 5 % ,血流速度异常增高 2 2 % ,血流速度正常 13%。结论 :多发性腔隙性脑梗死以双侧血流速度峰值对称性下降为主 (P <0 0 5 ) ,单发性腔隙性脑梗死由于侧支循环建立 ,血流速度峰值多正常 (P <0 0 5 ) ,腔隙性脑梗死引起的血流速度异常增高的病因多为高血压 ,TCD可作为腔隙性脑梗死的必要检测手段之一。
Objective:To observe parameters of chinky cerebral infarction on flow dynamics of intracrinial blood vessels.Methods:Cranial arteries flow parameters in 300 patients with chinky cerebral infarction diagnosed by CT or MRI were examined by Transcranial Doppld(TCD).Results:In 300 patients with chinky cerebral infarction,flow-velocity decreased in 194 cases (65%),unusually increased in 65 cases(22%),and still maintained normal in 41 cases (13%).Conclusions:The peak flow-velocity of intracrinial arteries in patients with multiple chinky cerebral infarction decreases symmetrically,that in patients with single chinky cerebral infarction maintains normal because of construction of branch circulation.The peak flow-velocity increases mainly in hypertention patients with chinky cerebral infarction. The results indicate that TCD will be one of the necessary detective way to chinky cerebral infarction.
