摘要 目的:探讨彩色多普勒超声在评价下肢深静脉瓣功能不全程度中的应用价值。方法:选取下肢深静脉瓣功能不全患者63例(患肢81条),正常对照组24例(肢体48条),进行下肢静脉彩色多普勒超声检查,观察第一对股浅静脉瓣的反流面积(RA)、反流时间(RT)、反流速度(RV),根据静脉逆行性造影结果对下肢深静脉瓣功能不全进行分级。结果:与对照组比较,病例组股浅静脉瓣RA增大、RT延长,两组间差异有统计学意义(P<0.05);超声测量的股浅静脉瓣RA与下肢深静脉瓣功能不全程度呈高度相关性(r=0.998),而RT、RV与反流程度相关性差(r=0.574、0.170)。结论:利用彩色多普勒超声所测量股浅静脉第一对瓣膜RA在评价下肢深静脉瓣功能不全程度中有意义,根据RA大小可以初步判断下肢深静脉瓣功能不全的程度。

AbstractObjective: To evaluate the diagnostic value of color Doppler flow imaging(CDFI) in lower limb deep venous insufficiency. Methods: Total 63 patients with lower limb deep venous insufficiency(81 affected limbs, patient group) and 24 cases of normal control(48 normal limbs, control group) were included in the study. Color Doppler ultrasound was used to observe various indexes of hemodynamic variations including reflux area(RA), reflux time(RT), and reflux velocity(RV) of the first pair of the superficial femoral vein valve. The grading of lower limb deep venous insufficiency was based on the results of lower extremity venous retrograde angiography. Results: There was a statistical difference in RA and RT between the patient group and the control group(P<0.05). There was a strong positive correlation between the superficial femoral vein valve RA estimated by color Doppler ultrasound and the reflux degree estimated by lower limb deep venous insufficiency(r=0.998). But poor correlation was observed about RT and RV(r=0.574, and r=0.170, respectively). Conclusion: CDFI can accurately measure the superficial femoral vein valve RA, which availably reflects the degree of lower limb superficial femoral vein valve reflux. Whereas, the RT and RV have no diagnostic significance for the grading of valvular regurgitation in the study.
