摘要
Abstract
Objective To study the diagnostic value of transcranial Doppler sonography (TCD) in the opening of intracranial collateral circulation in patients with internal carotid artery (ICA) occlusion or severe stenosis.Methods A total of 198 patients with ICAO or severe stenosis admitted to our hospital were selected and divided into CI group,TIA group and Asy group according to the clinical manifestation and results of head CT and MRI examination.The opening of intracranial collateral circulation in the three groups was detected with TCD to compare the collateral opening efficiency among the three groups and calculate the specificity and sensitivity of TCD in diagnosis of collateral circulation.Results Among the 198 patients,TCD detected 79 cases(39.90％) of internal and external carotid artery collateral circulation opening,98 cases (49.49％) of anterior communicating artery opening and 85 cases (42.93％) of posterior communicating artery opening.Compared with the results of DSA,TCD had 253 open collateral circulations in compliance with the results of DSA.There were 9 cases of false positive and 2 cases of false negative.The specificity of TCD in the diagnosis of collateral circulation opening was 90.43％,and the sensitivity was 99.21％;in the results of TCD detection,the internal and external carotid artery collateral circulation opening rate in TIA group was significantly higher than that in CI group and Asy group (P ＜ 0.05);the anterior and posterior communicating artery opening rate in Asy group was much higher than that in CI group and TIA group (P ＜ 0.05).Conclusion TCD has high specificity and sensitivity in the diagnosis of the opening of intracranial collateral circulation in patients with internal carotid artery (ICA) occlusion or severe stenosis and has high guiding value for clinical practice.关键词
