Comparative Study of Outcome of Duplex Ultrasound-Guided, Catheter-Directed Foam Sclerotherapy and Radio-frequency Ablation in the Management of Great Saphenous Varicose Veins

Chronic venous insufficiency of lower limbs is a common problem in adults. We compared the two modalities, namely duplex ultrasound-guided, catheter-directed foam sclerotherapy (UGFS) and radio-frequency ablation (RFA), in the management of great saphenous varicose veins using clinical assessment (Venous Clinical Severity Score, Venous Disability Score) and duplex imaging. Patients presenting with great saphenous vein (GSV) varicosity due to incompetent saphenofemoral junction (SFJ) were selected and randomly assigned in each arm, i.e., duplex UGFS group and RFA group. Patients were assessed on days 7, 30, and 90 both clinically and sonologically. Clinical assessment was based on the Venous Clinical Severity Score (VCSS) and Venous Disability Score (VDS). Obliteration of the treated GSV segment was noted in all the limbs of the RFA group (31/31) on duplex sonography on days 7, 30, and 90, while in the UGFS group, out of 30 limbs, obliteration was successful in 28 (28/30) and 2 had treatment failure. However, outcome of both the groups were statistically comparable (P value > 0.05). After the procedure, improvement in the VCSS was noted in both the study arms in every follow-up and both the modalities were found to be equally effective. Improvement in the Venous Disability Score was there on every follow-up, but maximum improvement was seen on the second visit, i.e., post-treatment day 30. Improvement was statistically significant and equal in both arms after the initial 1 week. Foam sclerotherapy, especially catheter-directed, is as effective as radio-frequency ablation in achieving anatomical obliteration and yielding relief in clinical signs and symptoms in patients with GSV varicosity with SFJ incompetence.
