Foam Sclerotherapy Combined with Surgical Treatment for Recurrent Varicose Veins: Short Term Results

ObjectiveTo study the short term results of combined peroperative foam sclerotherapy (PFS) and surgical treatment for recurrent varicose veins.MethodsPFS was used to treat 129 limbs with recurrent varices: 100 great saphenous (GSV), 29 small saphenous veins (SSV). Foam was prepared with 1% polidocanol mixed with 4 times its volume of air. The 100 GSVs comprised 28 trunks directly connected with the femoral vein, 28 connected to a lymph node venous network, 11 associated with perforators and 33 isolated trunks. The 29 SSVs comprised 4 trunks directly connected to the popliteal vein, 7 isolated trunks, 15 popliteal perforators and 3 recanalisations after SSV stripping. All operations included phlebectomies. In twenty limbs re-ligation of the SFJ and 4 SPJs was carried out. All were performed under local anaesthesia in an ambulatory setting. Patients were assessed clinically and by colour duplex ultrasound after 3 and 40 days follow-up.Results120 patients (93%) showed complete obliteration of saphenous trunks, junctions and varices. The 9 incomplete obliterations were 3 venous recanalisations in the SSV compartment and 6 perforators (4 popliteal and 2 femoral). Two asymptomatic deep venous thromboses were detected by colour duplex 3 days after operation.ConclusionPFS facilitates surgical treatment of recurrent varicose veins. There is a small risk of post-operative deep vein thrombosis.
