摘　　要：目的　监测人工心瓣膜患者脑动脉微栓子 ( MES)情况。方法　采用 Multi- Dop X4经颅多普勒超声 ( TCD)监测 2 0例人工心瓣膜患者脑动脉微栓子。结果　微栓子阳性 1 4例 ,阳性率为 70 % ,出现频率为0～ 31 9个 /30 min,相对强度为 1 1～ 42 (均数为 2 2 .9) d B,时间延迟为 0 .9～ 35 (均数为 1 1 .6) ms。结论　 TCD是监测人工心瓣膜患者脑动脉微栓子的较可靠的方法。Objective To monitor the cerebral arterial microembolic signals(MES) in patients with artificial heart vale.Methods The cerebral arterial MES were monitoring using Multi-Dop X4 Transcranial Doppler in 20 patients with artificial heart valve.Results 14 cases were monitored MES.The positive rate was 70%,MES frequency was 0~319/30min,MES relative intensity was 11~42(mean value 22.9)dB,the time was delayed 0.9~35(mean value 11.6)ms.Conclusions TCD is a reliably way to monitor the cerenbral arterial MES in patients with artificial heart valve.
