颈动脉扭曲的彩超诊断及其在颈部搏动性肿物超声鉴别诊断中的价值

目的介绍颈动脉扭曲的彩超诊断,探讨其在颈部搏动性肿物鉴别诊断中的价值。方法采用GE-VIVID7彩色多普勒超声诊断仪器,宽频探头7-11.4MHz,总结38例颈动脉扭曲患者的彩超表现。结果颈动脉扭曲的二维表现颈动脉走行弯曲,呈"S"形弯曲28例,呈"C"形弯曲9例,扭曲严重者可呈"A"型锐角样弯曲1例。CDFI示扭曲的血管内血流方向发生改变,形成涡流或湍流而呈现杂色血流。弯曲处流速加快,频谱充填。结论彩色多普勒超声检查可明确、快捷诊断颈动脉扭曲,从而有利于颈部搏动性肿物的鉴别诊断。

Differential diagnostic value of color Doppler ultrasonic examination on carotid distortion and cervical beating masses

Objective To introduce the ultrasonic diagnosis of carotid distortion and probe into its differential diagnostic value on cervical beating masses. Methods GE-VIVID 7 color Doppler ultrasonic apparatus with exploring caput of 7-11.4 MHz wide frequency, The color ultrasonic manifestations of 38 cases with carotid distortion were summarized. Results Carotid distortions in two dimensions manifested in curving forms, 28 cases in the form of "S", 9 cases "C" and 1 case in the form of "A" acute angle. CDFI showed the directions of blood stream had changed and shaped into whirpool displaying mottling blood stream in distorting vessels. The velocity of blood flow was expedited and frequency spectrum was filled in the curving vessels. Conclusions Carotid distortion can be diagnosed by color Doppler ultrasonic examination, which is propitious to ultrasonic differential diagnosis between cervical beating masses.
