The most common site of venous reflux is the long saphenous vein (LSV). The preferred treatment for reflux in the LSV is surgical stripping of the LSV. However, the complications of surgical stripping are well documented and undesirable. The constant search for treatment options with less morbidity, which are also cosmetically more acceptable, has resulted in the endovenous treatment for primary varicose veins, developed by VNUS Medical Technologies, Inc (Sunnyvale, Calif). We hereby present our first treatment experiences and propose refinements to the procedure. ⋯ The endovenous catheter should not be used more than 5 to 10 cm below the knee to prevent saphenous nerve damage. Performance of the procedure with bloodlessness is preferable. A result of 88% of successfully treated LSV segments indicates a promising alternative for surgical stripping of the LSV.

We prospectively investigated the patency of venous repair in a quantitative fashion with measurement of vein blood flow velocities after lower extremity injuries caused by either military or civilian trauma. ⋯ Venous repair has a high patency rate at the femoral and popliteal levels, but the patency rate for infrapopliteal venous repair is extremely poor because of low flow velocities. Therefore, we conclude that repair of infrapopliteal venous injuries is unnecessary.
