We used duplex sonography in patients with recurrent varicose veins after surgical treatment to detect any residual stump of the great saphenous vein at the sapheno-femoral venous junction, and we compared these sonographic findings with surgical findings as the "gold standard."
We prospectively studied 65 patients (54 women and 11 men) who had recurrent varicose veins 1-30 years (mean, 11 years) after surgical exploration of the groin and ligature of the great saphenous vein at its junction with the femoral vein. Duplex scans were performed in all patients before surgical reexploration. Sonographic findings were compared with surgical findings.
Duplex scanning revealed a residual stump in 47 patients (72%) and no stump in 15 patients (23%). Thirty-five (74%) of the 47 cases with a residual stump had reflux on duplex scans, and the remaining 12 cases (26%) showed no reflux. Findings in all 62 of these cases were confirmed by surgery. In only 3 patients (5%) did duplex scans fail to show a residual stump when surgery revealed a small residual stump without reflux.
Duplex scanning is the noninvasive diagnostic technique of choice to detect any residual stump of the great saphenous vein and to diagnose valve failure at the sapheno-femoral venous junction in patients with recurrent varicose veins.
我们对接受手术治疗后复发静脉曲张的患者进行了双功超声检查，以检测大隐静脉在隐股静脉交界处的任何残留残端，并将这些超声检查结果与作为“金标准”的手术结果进行比较。
我们前瞻性地研究了65例患者（54例女性和11例男性），他们在腹股沟手术探查并结扎大隐静脉与股静脉交界处后1至30年（平均11年）出现复发性静脉曲张。所有患者在再次手术探查前均进行了双功扫描。将超声检查结果与手术结果进行比较。
双功扫描显示47例患者（72%）有残留残端，15例患者（23%）无残端。47例有残留残端的患者中，35例（74%）在双功扫描时有反流，其余12例（26%）无反流。所有这62例患者的检查结果均经手术证实。只有3例患者（5%）在手术发现有小的无反流残留残端时，双功扫描未能显示残留残端。
双功扫描是检测复发性静脉曲张患者大隐静脉残留残端及诊断隐股静脉交界处瓣膜功能不全的首选非侵入性诊断技术。
