摘　　要：目的研究头臂动脉扩张的超声声像图特征及其临床价值。方法应用高频线阵探头(5～12MHz)对7例头臂动脉扩张的患者进行超声检查。结果典型的表现是:患者颈部有搏动性包块,头臂动脉长度增加,走行迂曲扩张,分叉点抬高至胸骨上窝的上方,血管内径增宽,内-中膜增厚,血管内可见红蓝参半的涡流信号。了解和辨认这些表现,对于诊断本病是很重要的。结论彩色多普勒超声对诊断头臂动脉扩张具有重要的临床价值。Objective To explore ultrasonographic features and diagnosic value of distended brachiocephalic trunk. Methods Seven cases of patients were examined using a high frequency（5-12MHz） linear array transducer. Results The ultrasonographic features of distended brachiocephalic trunk were as follows： the patients had pulsating mass on cervix, ultrasound showed that brachiocephalic trunk was longer, tortuous and dilatant; vascular bifucation were raised over suprasternal notch, the vascular diameters and intima-media thickness were increased, the color doppler flow imaging in the trunk was running red and blue parellel. Recognising these features was important for definite diagnosis of this disease. Conclusions We found that color doppler flow imaging plays a very important role for diagnosing distended brachiocephalic trunk.
