【摘要】 目的探讨彩超在大隐静脉曲张患者下肢深静脉血流状况检测中的应用价值。方法应用彩超,使用高频超声,对76例大隐静脉曲张患者的下肢深静脉结构及血流状况进行检测。应用二维超声观察静脉管壁、瓣膜厚度,测量管腔内径,观察有无静脉血栓形成。应用多普勒观察管腔内血流充盈状况,测量血流速度。通过乏氏试验及腓肠肌挤压试验观察静脉瓣功能,测量反流时间及反流速度。应用彩色多普勒观察静脉血栓形成后管腔再通情况。结果 76例大隐静脉曲张患者中,下肢深静脉瓣功能不全者40例,占总例数52.6%I,II级以上反流者33例。下肢深静脉血栓者4例,占总例数的5.3%。与下肢静脉造影结果对比,彩超诊断下肢深静脉病变的敏感性为95.7%,特异性为96.7%。结论部分大隐静脉曲张患者存在下肢深静脉病变。彩超检查大隐静脉曲张患者的下肢深静脉血流状况具有直观、无创、实时、可重复、价廉等优点,已成为此类疾病无创检查首选,并可为进一步有创检查及治疗方案的选择提供有价值的信息。更多还原

【Abstract】 Objective To assess the value of color Doppler ultrasonography in detection of blood flow in deep veins of lower limb with varicosis of great saphenous vein.Methods Color Doppler ultrasonography and high frequency ultrasonography were used to detect state of blood flow in deep veins of lower limbs in 76 patients.2D ultrasonography was applied to examine vessel wall and thickness of valve,to measure the inner diameter and to diagnose thrombosis of vein.Color Doppler ultrasonography was used to observe blood flow engorgement and to measure blood flow rate.Valsalva test and gastrocnemius muscle squeeze test were applied to observe the function of venous valve and to measure contraflow time and speed.Color Doppler ultrasosography was used to observe the luminal recanalization after thrombosis.Results In 76 patients with varicosis of great saphenous vein,there were 40 cases with venous valve functional defect in deep vein of lower limb,the incidence rate was 52.6%.There were 4 cases with thrombosis in deep vein of lower limb,and the incidence rate was 5.3%.Compared with the diagnostic rate of pathological changes in deep vein of lower limbs by angiography,the diagnostic sensitivity and specificity of color Doppler ultrasonography were 95.7% and 96.7% respectively.Conclusion Pathological changes happened in part of patients with great saphenous vein phlebeurysma.Color Doppler ultrasonography is direct-viewing,non-invasive,real-time,repeatable and cheap,it is the first choice for detection of such kind of disease and it can provide valuable information for further examination with invasive method and selection of treatment plan.更多还原
