经颅多普勒检测破裂脑动脉瘤栓塞术后脑血管痉挛的临床应用
Clinical application of TCD in the detection of cerebral vasospasm after embolization of cerebral ruptured aneurysms
摘要
Abstract
Objective To investigate the application value of transcranial Doppler(TCD) in the diagnosis of cerebral vasospasm (CVS) following cerebral aneurysm embolization.Methods From May 2013 to August 2016,46 patients with ruptured aneurysm of the brain were treated with arterial embolization in our hospital.All patients underwent TCD examination to detect the middle cerebral artery (MCA) blood flow velocity and the arterial inflow velocity (eICA) of the internal carotid artery,so as to determine whether the cerebral vasospasm occurred or not.DSA was used to compare the sensitivity and specificity of TCD in the diagnosis of cerebral vasospasm.Results The postoperative blood flow rate of MCA increased significantly since the third day.After operation,10d decreased gradually,but compared with before operation, the difference was significant (P<0.05).24 cases of CVS were diagnosed by DSA examination,Non CVS patients were 22 cases,The blood flow velocity of MCA in CVS patients was significantly higher than that in non CVS patients (P<0.05) after 3D.The DSA test results are used as the gold standard.At the same time with MCA blood flow rate>120cm/s as a criterion for vasospasm in TCD.The sensitivity,specificity,positive predictive value and negative predictive value of TCD for diagnosis of CVS was 9.17%,90.91%,90.48% and 80.00%,respectively.Conclusion TCD can early detect the occurrence of CVS after embolization of aneurysms,It has high sensitivity and specificity, which was worthy of further study.关键词
