Great Saphenous Vein Ablation with Steam Injection: Results of a Multicentre Study

ObjectiveTo assess the safety and efficiency of steam vein sclerosis (SVS) of the great saphenous vein (GSV) in a multicentre open prospective cohort study.Design75 consecutive adult patients with GSV reflux, CEAP C2–C5 and vein diameter 4–13 mm.MethodsPatients treated using an SVS™ generator delivering homogenous pulses of superheated steam were followed up at 8 days and 1, 3, 6 and 12 months (clinical, duplex ultrasound, quality of life [QoL] with SF12).Results88 veins were treated in 75 patients. At 6 months, 72/75 (96%) veins were obliterated (95% CI: 89–99) and Kaplan–Meier analysis found an obliteration rate of 96.1% at 12 months. QoL increased at 6 months for both the physical and mental components (p = 0.049 and p < 0.001 respectively). SVS was well tolerated: no major complications were reported. Adverse events occurred mainly at day 8 and incidents amounted to ecchymosis (n = 60) and pain (n = 7).ConclusionsSVS achieved an obliteration rate similar to that of other thermal ablation techniques. It was well tolerated with minimal post-operative pain.
