经颅多普勒及数字减影血管造影对分水岭缺血性脑卒中诊断价值研究

摘要

目的 研究经颅多普勒(TCD)以及数字减影血管造影(DSA)在检查分水岭缺血性脑卒中颅内血管状况的价值. 方法 选取2015年3月至2016年1月我院收治的分水岭缺血性脑卒中病人98例,对所有病人进行TCD以及DSA检查,分析病人颅内血管的狭窄情况和侧支循环代偿情况,总结TCD和DSA对分水岭缺血性脑卒中病人的颅内血管状况的诊断价值. 结果 在对病人颅内血管狭窄情况的诊断中,TCD和DSA的检出率、灵敏度以及特异度差异无统计学意义(P>0.05).在对病人侧支循环代偿情况的诊断中,TCD和DSA对前交通动脉代偿的诊断差异没有统计学意义(P>0.05);TCD对后交通动脉代偿、软脑膜动脉代偿的诊断率低于DSA(P<0.05),对眼动脉代偿的诊断率高于DSA(P<0.05). 结论 对分水岭缺血性脑卒中病人而言,TCD和DSA检查可以有效诊断其颅内血管状况,具有较高的临床诊断应用价值.%Objective To study the value of transcranial Doppler(TCD) and digital subtraction angiography(DSA) on checking intracranial vascular state in patients with watershed ischemic stroke.Methods Ninety-eight patients with watershed ischemic stroke were selected from March 2015 to January 2016 in our hospital, and all patients were checked by TCD and DSA to diagnose intracranial vascular stenosis and compensatory collateral circulation.Results In the diagnosis of intracranial vascular stenosis of patients, the detection rate, sensitivity and specificity of TCD and DSA showed no significant differences (P>0.05).In the diagnosis of compensatory collateral circulation of patients, TCD showed no significant difference in the detection rate of anterior communicating artery compensatory (P> 0.05), but showing significant difference in posterior communicating artery, ophthalmic artery and pial artery compensatory(P<0.05).Conclusions For patients with watershed ischemic stroke, TCD and DSA examination can check the intracranial vascular conditions effectively.
