【摘要】 目的探讨彩超在股浅静脉第一对瓣膜功能不全时手术前的临床价值。方法回顾经临床确诊,采用PTFE人工血管补片环缩股静脉瓣膜治疗的36例42条下肢深静脉瓣膜功能不全患者,术前彩色多普勒超声对患肢股浅静脉第一对瓣膜反流血流显像及频谱多普勒进行分析,并与数字减影血管造影(DSA)及手术结果进行比较。结果36例42条下肢深静脉瓣膜功能不全患者,股浅静脉第一对瓣膜处反流血流持续时间均>0.5秒。结论股浅静脉第一对瓣膜反流血流显像及频谱多普勒特征,尤其反流持续时间大于0.5秒,可以作为原发性下肢深静脉瓣膜功能不全患者行自体静脉片环缩股静脉瓣膜手术治疗前的一项较为可靠的指标。更多还原

【Abstract】 Objective To explore the clinical value of Doppler in evaluating the first valae of superficial femoral vein before the operation of primary lower extremity deep venous insufficiency.Methods A retrospective analysis was done in 36 patients(42 limbs) with primary lower extremity deep venous insufficiency,and all patients were treated by using polytetrafluroethylene(PTFE) to encircle constriction the value of femoral vein.Reflux of blood flow imagine and spectrum of first valve of superficial femoral vein was analyzed by color Doppler in preoperative which compared with the results of digital subtraction radiography(DSA) and operation.Results The duration of back flow of first valve of superficial femoral vein in patients exceed 0.5s.Conclusion The back flow display and spectrum features of first valve of superficial femoral vein is reliable indicator,especially the duration of back flow(>0.5s) for encircle contraction therapy of primary lower extremity deep venous insufficiency.更多还原
