摘要
目的探讨多层螺旋CT血管成像(CTA)对头颈部动脉狭窄的临床应用价值。方法对100例先行头颈血管CTA检查,后行血管造影(DSA)检查的患者,有针对性地观察椎动脉起始部、颈内动脉分叉段(分叉上下各4cm)、大脑前动脉A1-2段、大脑中动脉M1-2段、椎动脉V1-5段(每例10段,共1000段)的CTA、DSA显示血管狭窄的情况、血管狭窄程度,以DSA显示结果为金标准,将两组结果进行比对分析。结果在100例病例中,CTA及DSA影像均显示满意,与DSA相比较狭窄的总敏感度为99.2%(253/255),特异性为99.7%(743/745)。结论 CTA头颈部动脉狭窄病变的显示具有独特的优势,是一种可靠、无创、有应用价值的检查方法。
Objective To study the clinical application of muhislice spiral CT angiography （CTA） in the diag- nosis of neck and cranial arteries stenosis. Methods 100 patients underwent DSA after CTA. The hemadostenosis re- lated results of both CTA and DSA images about the initiation part of vertebral artery,internal carotid artery bifurca- tion（4 cm in both upper and under portions） ,the A1 2 part of the anterior cerebral artery, M 1 part of 2 cerebral mid- dle artery,V15 part of vertebral artery（each case had 10 parts with a total of 1000 parts） were compared and ana- lyzed. And the result showed by DSA was served as the golden standard. Results images of both CTA and DSA for 100 patients were satisfactory. And compared with DSA, the sensitivity and specificity of multislice CTA in detecting neck and cranial arteries stenosis were 99.2 % and 99.7 %, respectively. Conclusion The diagnosis of neck and cranial arteries stenosis by CTA is a reliable and atraumatic detection method with its unique advantages, and worthy of being widely applied in clinic.
