摘要
目的探讨经颅多普勒超声(TCD)检查对蛛网膜下腔出血(SAH)后脑血管痉挛(CVS)的诊断价值。方法应用TCD对30例SAH患者脑血流状况进行动态监测,并结合临床表现、头颅影像学资料进行分析。结果经TCD证实,本组17例(56.7%)发生CVS,其中10例无症状,7例出现CVS症状。头颅CTFisher分级中,Ⅲ、Ⅳ级SAH患者中CVS的发生率明显高于Ⅰ、Ⅱ级(均P<0.05)。结论TCD监测是早期发现SAH后CVS的一种敏感的检查手段。
Objective To explore the value of transcranial Doppler ultrasonography （TCD） on diagnosing the cerebral vasospasm （CVS） following subarachnoid hemorrhage （ SAH ）. Methods TCD was used to detect and monitor the cerebral blood flow status to estimate CVS following SAH in 30 cases, then the results of TCD were analyzed by combining with clinical manifestation and SAH severity on CT. Results 17 patients （56. 7% ） had the evidence of CVS confirmed by TCD, 10 of them were nonsymptomatic and 7 were symptomatic. The incidences of CVS in patients with Fisher grade Ⅲand Ⅳ were more higher than grade Ⅰand Ⅱ（ P 〈 0. 05 ）. Conclusion TCD is a sensitive method for the early diagnosis of patients with the CVS following SAH.
