颈动脉超声联合经颅多普勒超声对缺血性脑血管病的诊断价值

The value and significance of combined carotid ultrasound and transcranial Doppler ultrasound in ischemic cerebrovascular diseases

目的探讨颈动脉超声与经颅多普勒超声联合在缺血性脑血管疾病中的价值及意义分析。方法选取2018-01—2019-12在济源市人民医院接受缺血性脑血管疾病治疗的308例患者为研究组。并选取同时期进行体检的150名健康者作为对照组。2组均行颈动脉超声与经颅多普勒超声联合检测,并比较其检测结果。结果研究组椎动脉及基底动脉的Vm低于对照组,而PI指数则高于对照组(P<0.05);经颅多普勒与颈动脉超声联合检测的敏感性为97.0%(228/235)、特异性为86.3%(63/73)、阳性预测值为95.8%(228/238),均高于单纯的经颅多普勒超声的88.1%(207/235)、71.2%(52/73)、90.8%(207/228),2组比较存在明显差异(P<0.05)。结论对缺血性脑血管疾病患者采用颈动脉超声与经颅多普勒超声联合的检测方法,能够有助于对病情进行及时、有效的判定,且符合度相对较高,利于临床治疗方案的确立及有效实施。

Objective To investigate the value and significance of combined carotid ultrasound and transcranial Doppler ultrasound in ischemic cerebrovascular diseases.Methods 308 patients who received treatment for ischemic cerebrovascular disease in our hospital in January,2018 and December,2019 were selected as the study group.A total of 150 healthy patients who underwent physical examination in our hospital at the same time were selected as the control group.Carotid ultrasound and transcranial Doppler ultrasound were used in both groups and the results were compared.Results Vm of vertebral artery and basilar artery in the study group was lower than that of the control group,while PI index was higher than that of the control group(P<0.05).The sensitivity,specificity and positive predictive value of TCD combined with carotid ultrasound were 97.0%(228/235),86.3%(63/73)and 95.8%(228/238),which were all higher than that of TCD alone(88.1%(207/235),71.2%(52/73)and 90.8%(207/228),and there were significant differences between the two groups(P<0.05).Conclusion The combined detection method of carotid artery ultrasound and transcranial Doppler ultrasound in patients with ischemic cerebrovascular disease can help to timely and effectively determine the condition,and the degree of compliance is relatively high,which is conducive to the establishment and effective implementation of clinical treatment program.
