彩色多普勒超声与DSA诊断缺血性脑血管病患者颅外段颈动脉狭窄的对照研究
Controll Study on the Diagnosis of Extracranial Carotid Stenosis in Patients with Ischemic Cerebrovascular Disease with Color Doppler Flow Image and DSA
摘要
Abstract
Objective:To investigate the values of color doppler flow image ( CDFI ) and digital sub-traction angiography ( DSA) in diagnosing extracranial carotid stenosis in patients with ischemic cerebrovascu-lar disease. Methods:A total of 50 patients with ischemic cerebrovascular disease were selected and examined by CDFI and DSA. With the DSA result as a gold standard, the concordance between the results of the two methods was analyzed. Results:The detectable rates of CDFI and DSA were 84.00% and 76.00% respective-ly, and the difference was statistically insignificant ( P>0.05);and the two methods had insignificantly differ-ent results of degree of carotid stenosis ( P>0.05) . There was good concordance between the degree of carotid stenosis revealed by CDFI and that revealed by DSA ( Kappa value=0.7512, P<0.05) . The sensitivity, speci-ficity, accuracy, positive predictive value, and negative predictive value of CDFI in diagnosis of carotid steno-sis were 88.10%, 87. 50%, 88. 00%, 97. 37%, and 58. 33%, respectively. Conclusion: CDFI is fairly ac-cordant with DSA in detectable rate of carotid stenosis and judgment of the degree of the stenosis, without wound, repeatable, and is applicable to the screening of extracranial carotid stenosis.关键词
