BACKGROUND: Ultrasound guided sclerotherapy (UGS) in the treatment of the superficial venous system.
METHODS: Between 1999 and 2000, 100 patients were treated, with an average of 56 years, with severe reflux (same or higher duration than 4 sec) at the superficial vernous system, comunicate and/or perforator system and no systemic varicose veins. One hundred and thirty-nine UGS were performed: 125 in long saphenous vein (LSV) and 14 in short saphenous vein (SSV); the sclerosat employed was Polydocanol in a 3% and 4% concentration, using 3 cc dosages (per session). The clinical and ultrasound follow-up were at: 7, 14 and 28 days and 3 and 6 months, respectively. One and 4 sessions with intervals of 3 and 4 weeks were necessary.
RESULTS: 1) Subjective impression:
— great improvement: LSV 113, SSV 11;
— light improvement: LSV 10, SSV 3;
— no improvement: LSV 2, SSV 0.
2) Objective Impression (Duplex scanning):
— whole occlusion (100%): LSV 108, SSV 12;
— partial occlusion (50-75%); LSV 15, SSV 2;
— without occlusion: LSV 2; SSV 0.
CONCLUSIONS: UGS were effective in 90% of the patients, with a 2 year long follow-up.
