目的：评价急诊颈部血管超声（cervical vascular ultrasound，CVUS）检查在急性脑梗死患者中的应用价值。方法62例急性脑梗死患者，均到院后行急诊颈部血管超声检查，入院后常规行择期颈部血管螺旋CT血管造影（spiral CT angiography，SCTA）以及头颅血管螺旋CT血管造影，观察不同检查诊断颈动脉狭窄的检出率、狭窄程度及斑块的检出率，分析急诊颈部血管超声检查、CT血管造影检查结果与急性脑梗死患者的临床资料：动脉血管狭窄程度、斑块部位、斑块性质、梗死部位。结果62脑梗死患者中，不同检查颈部动脉狭窄的检出率分别为：CVUS 72.6%，SCTA 77.4%，两种检查方法比较差异无统计学意义（P>0.05），SCTA对血管轻重度狭窄诊断略高于CVUS，对重度狭窄或闭塞诊断结果一致；两种检查方法颈部动脉血管斑块检出率SCTA略高于CVUS,但差异无统计学意义（P>0.05）；急诊颈部动脉血管超声检查检出的斑块与脑梗死梗死灶同侧的比率为84.4%。结论 CVUS检查安全、快速、无创伤，诊断颈部血管狭窄、斑块符合率较高，可用于急性脑梗死患者急性期颈部动脉系统的筛查，对急性脑梗死的治疗有重要的指导作用。“,”Objective To investigate the clinical value of emergency application of cervical vascular ultrasound (CVUS) in diagnosis of cerebral infarction . Methods Sixty-two patients with confirmed cerebral infarction underwent CVUS in the emergency room and then underwent spiral CT angiography (SCTA) after admission. The detection rates of arterial stenosis and existance of plaques were compared. Results The detection rate of stenosis in cervical artery by CVUS was 72.6%, not significantly different from that by SCTA (77.4%, P0.05). Emergency CVUS showed that 84%of the plaques were ipsilateral with the cerebral infarction. Conclusion Safe, noninvasive, rapid, and sensitive, emergency CVUS is a valuable measure for diagnosis of cerebral infarction.
