小腿交通静脉病变的彩色多普勒超声表现与临床表现分级的相关性研究

Relationship between color Doppler ultrasound features of the insufficient perforating veins and clinical stages of chronic venous insufficiency

目的:探讨下肢静脉功能不全患者小腿交通静脉超声改变与临床表现的关系。方法:用彩色多普勒超声检查下肢静脉功能不全患者45例50条下肢的小腿交通静脉的数目、部位、内径及血流速度,并分别与患者的临床表现分级进行相关性分析。结果:彩色多普勒超声检出交通静脉扩张的“数目、内径及血流速度”与患者临床表现分级呈正相关,相关系数分别为0.48、0.55、0.51,P值均<0.05。结论:随小腿扩张交通静脉数目增加、内径增宽、血流速度升高,临床表现加重。

Objective： To evaluate the relationship between the ultrasonic features of perforating veins（PVs） and the clinical stages in patients with venous insufficiency of lower extremities. Methods： In 45 cases （50 lower limbs） with differernt clinical stages of venous incompetence of lower extremities, the number, diameter and blood flow velocity of PVs were examined by color Doppler ultrasound. Results： There were positive relationships between PVs＇ number, diameter or blood flow velocity and the clinical stages, with a relationship index of 0.48, 0.55 and 0.51, respectively（P〈0.05）. Conclusion： Higher clinical stages were accompanied with greater number, wider diameter or faster blood flow of PVs.
