摘　　要：本文报告了我院１９９１年８月至１９９２年１２月间２２例脑动静脉畸形（ＡＶＭ）经ＴＣＤ检测的结果，并观察了进行微导管栓塞（ＤＳＡ）治疗前后ＴＣＤ的变化，结果为：①检出供血动脉５１支，平均每例２、３支。检测供血动脉ＴＣＤ与ＤＳＡ造影结果相符率为９５．５％。②４例ＴＣＤ诊断困难，均为轻度者，确诊率为８１．８％。③本组血流速度增高平均为１２６．７±３３．４（ｃｍ／ｓｅｃ），ＰＩ降低，平均为０．５１，频谱异常占８１．８％，声频异常占６３．６％。④经栓塞治疗后，ＴＣＤ改变明显，血流速度平均降低２９．２（ｃｍ／ｓｅｃ），ＰＩ升高０．２５，频谱及声频均有明显好转。Transcranial Doppler (TCD) eveluation of the intracranial arteriovenous malformation (AVM) and the microtubule embolization therapy effect was performed in 22 patients recently in our hospital. The results have shown:(1) 51 hemodynamic arteries were detected with an average of 2、3 arteries in each case. This result have a sameness rate of 95.5% with digital subtraction angiography(DSA); (2) 4 difficult cases of mild AVM and 15 cases of severe AVM were detected including 4 difficult cases in diagnosis. The correct diagnostic rate was 81.8%; (3) the average blood velocity increasing was 126. 7±33.4 with a mean PI decreasing of 0. 51; (4)There was a significant change in TCD after embolization theraphy, The average decreasing of blood velocity was 29.2 with a mean PI increasing of 0.25. We have the conclusion that TCD is valuable in the diagnosis of AVM, TCD can detect the intracranial artery and evelate the treament of AVM well.
