Closed subfascial ligation of incompetent perforating veins of the lower extremities

The purpose of this study was to determine the effectiveness of minimally invasive surgical procedures for interrupting incompetent perforating veins of the lower limb. A closed subfascial ligation was performed in 20 patients who had incompetent perforating veins in 28 limbs as diagnosed by a clinical examination and duplex scanning. Two small transverse incisions measuring 5 10 mm in length were made on both sides of the incompetent perforating vein. Using an aneurysmal needle, a suture ( polypropylene No. 1) was placed in the subfascial plane to encircle the incompetent perforating vein from all directions. Next, this suture was tied through two incisions to ligate this perforator. The mean follow-up period was 26 months. The ligation of the incompetent perforators was successful in 27 of 28 limbs and no wound complications were observed. A closed subfascial ligation of incompetent perforating veins of the lower limbs is thus considered to be easy to perform, not overly invasive, safe, and to also have very encouraging results.
