| 目的 用经颅多普勒(TCD) 进行监护,了解脑动静脉畸形(AVM)供血状况及其变化。方法 AVM 患者11 例,均经股动脉穿刺插管后行栓塞治疗。分别于栓塞前、中、后全程动态监护AVM 血流状态变化。以大脑前、中、后动脉血流速度(BFV)和脉动指数(PI) 为观察指标。结果 11 例中有10 例显示明显的TCD变化。AVM 体积越大,血流量越大,流速增高,PI下降。频谱形态变化明显。栓塞后,供血动脉主干流速下降,PI升高,其测量值与栓塞前比较有统计学意义(P< 0.05),频谱形态趋于恢复。结论 TCD 可敏感地反映AVM 栓塞过程中血流状态变化,对了解栓塞程度具有重要意义。 |

| Objective Transcranial Doppler (TCD) monitoring is to detect the status and change of main blood supply of cerebral arteriovenous malformation (AVM).Methods 11 cases of AVM were embolized by puncturing and intubating to the femoral artery.The blood flow of these cases were continually monitored in 3 stages:peri,mid and post of embolization.The blood flow velocity (BFV) and pulsed index (PI) were observed in anterior cerebral artery (ACA),middle cerebral artery (MCA) and posterior cerebral artery (PCA).Results 10 of 11 cases had obvious changes of TCD.The larger of AVM,the more amount of blood flow.When BFV increased,PI decreased.The spectrum changed dramatically.After embolization,BFV reduced and PI raised.The spectrum gradually restored to normal.There was a significant difference before and after embolization.Conclusion TCD could show the status of blood flow sensitively during embolization which indicated the degree of embolizing. |
