Limited anterior plication (LAP) of the incompetent femoral vein was used in 2 groups of subjects with venous hypertension due to deep and superficial venous incompetence. Group 1 subjects were treated only with superficial veins surgery while groups 2 was treated with external valvuloplasty (LAP) at the level of the incompetent femoral vein. The plication was performed at the anterior side of the vein after limited dissection and manipulation. During a two-year follow-up the results of LAP were evaluated with color-duplex and ambulatory venous pressure (AVP) measurements. Nine of the 11 femoral veins treated with LAP were competent after 2 years (in 2 the incompetence was reduced). A lower AVP and RT was found in subjects treated with LAP in comparison with those in Group 1. Also the number of recurrent varicose veins (incompetent venous sites) and the average diameter of the femoral vein were higher in Group 2 (superficial surgery only). As no complications were observed LAP can be considered an alternative to the standard external valvuloplasty in cases of moderate incompetence when valve cusps are present and functional and incompetence is mainly due to relative enlargement of the vein diameter.
对两组因深浅静脉功能不全导致静脉高压的受试者采用了股静脉功能不全的有限前路折叠术(LAP)。第1组受试者仅接受浅静脉手术,而第2组在股静脉功能不全水平接受了外部瓣膜成形术(LAP)。在有限的解剖和操作后,在静脉前侧进行折叠术。在两年的随访期间,通过彩色双功超声和动态静脉压(AVP)测量评估LAP的结果。接受LAP治疗的11条股静脉中有9条在2年后功能正常(2条静脉功能不全有所减轻)。与第1组相比,接受LAP治疗的受试者的AVP和反流时间(RT)更低。此外,第2组(仅接受浅静脉手术)的复发性静脉曲张(静脉功能不全部位)数量和股静脉平均直径更高。由于未观察到并发症,在瓣膜尖存在且功能正常、功能不全主要是由于静脉直径相对增大导致中度功能不全的情况下,LAP可被视为标准外部瓣膜成形术的替代方法。
