目的:通过对缺血性脑卒中急性期TCD观察,并于CT进行比较,以探讨西宁地区TCD对缺血性脑卒中早期诊断价值。方法:对50例首次发病住院患者于24h内进行床旁TCD检查及CT检查,门诊健康体检者为对照组,检查结果进行统计学比较。结果:脑卒中组TCD检测结果,病侧MCAVm降低、ACAVm升高,分别与自身健侧及对照组比较差别有显著性(P<0.01)。病例组TCD和CT两种检测结果进行X2检验,X2=39.208,P<0.001,差别有显著性。结论:在西宁地区缺血性脑卒中急性期TCD异常率高于CT,具有较高的早期诊断价值。
OBJECTIVE: To evaluate the early diagnosis of ischemic stroke by observing TCD in ischemic stroke in acute stage and comparing it with CT in Xining area. Methods: 50 cases of first-time inpatient hospital bedside TCD examination and CT examination, outpatient physical examination for the control group, the test results were statistically compared. Results: The results of TCD in stroke group showed that MCAVm decreased and ACAVm increased, which was significantly different from that in control group (P <0.01). Case TCD and CT test results were X2 test, X2 = 39.208, P <0.001, the difference was significant. Conclusion: The abnormal rate of TCD in acute stage of ischemic stroke in Xining is higher than that of CT, which has high diagnostic value in early stage.
