【摘要】 目的　研究彩色多普勒超声检测股浅静脉内血流反流距离在评判下肢深静脉功能不全反流程度中的价值。方法　对 45例(46条下肢)经X线逆行血管造影确诊的不同程度的原发性下肢深静脉功能不全的患者和同期无年龄差异的自愿者 20例(40条下肢)进行彩色多普勒超声检查,对两组的超声检查结果进行对比分析。对患病组的X线逆行血管造影结果和超声测量的反流距离进行等级相关性分析。结果　超声测得股浅静脉内径与X线检查的深静脉反流程度高度相关 (r=0. 771, P<0. 05)。超声测得股浅静脉反流时间与X线检查的深静脉反流程度无相关性 (r=0. 247, P>0. 05 ),但反流距离与X线检查的反流程度高度相关 (r=0. 910,P<0. 05)。结论　利用彩色多普勒超声测量股浅静脉内血流的反流距离在评判下肢深静脉功能不全和反流程度中有重要价值。更多还原

【Abstract】 Objective To study the value of color Doppler ultrasonography in assessing the severity of deep venous insufficiency of the lower extremities.Methods Forty-five patients (46 lower extremities) in patient group confirmed as venous insufficiency by descending phlebography and 20 volunteers (40 lower extremities) in control group were assessed by color Doppler ultrasonography. The results of 45 patients were compared with those of 20 volunteers.Results The diameters of superficial femoral vein measured by color Doppler ultrasonography were correlated with the severity of venous reflux showed in phlebography(r=(0.771),P<(0.05)).And the distance of reflux was correlated with the severity of venous reflux showed in phlebography (r=(0.910),P<(0.05)),but not the reflux time (r=(0.247),P>(0.05)).Conclusions The reflux distance in superficial femoral vein is a useful parameter in assessing the degree of venous insufficiency.更多还原
