Randomized Controlled Trial Comparative Study Clinical Trial
External femoral vein valvuloplasty with limited anterior plication (LAP): a 10-year randomized, follow-up study.
The aim of this study was to evaluate the effects after 10 years of external valvuloplasty of the femoral vein (limited anterior plication or LAP). After informed consent patients with venous hypertension due to deep and superficial venous incompetence were randomized into two treatment groups. Both groups were treated with superficial vein surgery (ligation and section of the major incompetent superficial veins). ⋯ Also the average diameter of the vein was smaller in the LAP group. Moreover, QLS was significantly better in the LAP group after 10 years. In conclusion, in selected subjects, with moderate deep venous incompetence, functional cusps, or incompetence mainly due to relative enlargement of the femoral vein, LAP may be an effective alternative to external valvuloplasty.
