目的应用血管彩超检测颈内动脉扭曲患者的血流动力学情况,探讨颈内动脉扭曲角度与血流变化的关系及重度颈内动脉扭曲手术指征的评估.方法应用彩超检测45例颈动脉扭曲患者扭曲前后的收缩期血流速度(PSV)和舒张末期血流速度(EDV).分析不同级别颈内动脉扭曲患者血流速度的变化情况.结果 45例患者中Metz Ⅰ级17例,MetzⅡ级17例,MetzⅢ级11例.随着颈动脉扭曲角度的变小,对血流动力学的影响越来越明显,MetzⅢ级(Z=-2.934,P=0.003),MetzⅡ级(Z=-3.053,P=0.002)的患者扭曲后与扭曲处的PSV差异有统计学意义,而Metz Ⅰ级(Z=-0.382,P=0.702)患者扭曲后与扭曲处的PSV差异无统计学意义.扭曲角度与PSV扭曲处/PSV扭曲后比值存在负相关关系(r=-0.842,P＜0.05).结论重度颈动脉扭曲严重影响颈动脉的血流动力学,彩超可以准确地检测扭曲动脉的血流动力学变化.

Objective Colour ultrasound was used to detect the hemodynamic changes in patients with internal carotid artery kingking,in order to investigate the relationship between the carotid distortion angle and blood flow changes and to explore the assessment of severe internal carotid artery twist operation indications.Methods Forty-five patients with carotid artery kingking hospitalized in the Brain Hospital of Liaocheng were performed colour ultrasound to detect systolic blood flow velocity (PSV), end-diastolic velocity EDV) and to measure the angle of carotid artery kingking.Results According Metz classification, of the 45 patients, Ⅰ level 17 cases, Ⅱ level 17 cases, Ⅲ level 11 cases.With the decrease of carotid distortion angle,the influence on hemodynamics was more and more obvious, especially while the angle less than 30 degrees, the carotid artery blood flow was severely affected.The difference of PSV before and after Kinking was statistically significant in patientes of Metz Ⅲ level (Z=-2.934,P=0.003) and Metz Ⅱ level (Z=-3.053,P=0.002), but was statistically no significant in patientes of Metz Ⅰ level (Z=-0.382, P=0.702).There was a negative correlation between the ratio of the twist angle and PSV before kinking/PSV after kinking (rz =-0.842, P ＜0.05),that was, with the decrease of the twist angle, PSV before kinking/ PSV after kinking increase accordingly.Conclusion Kinking seriously affect the carotid artery blood flow dynamics.Ultrasound can accurately detect distortions arterial hemodynamics
