摘要
目的探讨彩色多普勒(CDFl)在颈动脉硬化狭窄中的临床诊断价值.方法分别检测87例住院和门诊患者的颈动脉和100例正常人的颈动脉,共314支血管,应用超声技术测量双侧颈总动脉分叉处及颈内动脉后壁内膜-中膜厚度(IMT)及斑块形成情况.结果CDFI显示136支颈总或/和颈内动脉内-中膜增厚,97支伴有斑块形成,31支管腔狭窄,程度约40%～95%,平均为76%,1例颈内动脉闭塞,238支颈动脉正常.结论超声检查在颅外段颈动脉管壁病变方面可作为一种优良的观测手段,并且能准确地判定颈动脉硬化程度和管腔狭窄程度及狭窄位置,为临床提供可靠诊断依据,也能用作治疗后随访手段.
Objective To evaluate the clinical value of color Doppler flow imaging （CDFI） in carotid stcnosis. Methods Ultrasound examination was performed on 187 cases （87 patients, 100 health persons） 314 carotid arteries were taken to measure the intima- media thickness（IMT） and detect the plague development of carotid artery. Results The thickening of the intima - media layer of common and/or internal carotid artery wall in 136 sides, the hyperechoic plaque in 97 sides, as well as the carotid stenosis in 31 sides were detected. The range of carotid stenosis was 40% - 95% ,and the median was 76%. One patient＇ s internal carotid was occluded. The carotid arteries in 238 patients were normal. Conclusion The lesions on extracranial carotid artery wall reveal sensitively, and the degree of carotid stenosis is diagnosed accurately with CDFI.
