Endovenous saphenous vein ablation in patients with acute isolated superficial-vein thrombosis.

ABSTRACT

OBJECTIVE: The possible benefits of endovenous saphenous ablation (EVSA) as initial treatment in patients presenting with isolated superficial-vein thrombosis (SVT) and saphenous vein reflux include (1) definitive treatment of the underlying pathology and (2) elimination of the saphenous vein as a path for pulmonary emboli, which (3) may eliminate the need for anticoagulation. METHODS: In a ten-year review of 115 limbs presenting with acute isolated SVT, 72 limbs (71 patients) with saphenous reflux were given a choice of two treatments following an explanation of the risks and benefits of each. Group I limbs (n = 41) were treated with office EVSA using radiofrequency or laser with or without thrombophlebectomy if performed within 45 days of diagnosis. Post-treatment anticoagulants were not given. Group II limbs (n = 31) were treated with compression hose and repeat Duplex within one week, with added anticoagulants if SVT extended into the thigh. RESULTS: In group I, mean interval from diagnosis to treatment was 13.7 days. One calf deep vein thrombosis was noted. In group II no complications were noted. In late follow-up of group II patients, 12/29 underwent EVSA more than 45 days after initial presentation. CONCLUSIONS: The safety and efficacy of EVSA and thrombophlebectomy appear indistinguishable from conservative measures and may be offered as initial treatment to patients presenting with SVT and saphenous reflux.
