Abstract
Objectives: To compare foam sclerotherapy through the access sheath (transluminal foam sclerotherapy [TLFS]) combined with endovenous laser ablation (EVLA) with EVLA alone in terms of safety and one-year venous clinical severity score (VCSS) changes in patients with small saphenous vein incompetence.
Methods: During EVLA, the sheath tip was placed around the targeted tributary vein, and the sclerosant was injected via the side port. Outcomes assessed at 1 day, 1 week, 1 month, and 1 year included VCSS changes, residual or recurrent reflux, the need for secondary interventions, and other related complications.
Results: The change in VCSS did not reach the minimum clinically important difference. Otherwise, TLFS reduced residual or recurrent reflux of the tributary using the TLFS (3/74 legs) compared with the EVLA alone (12/77 legs) (p = .027).
Conclusions: TLFS is a safe and feasible procedure that reduces residual or recurrent reflux of the tributary vein compared with truncal EVLA alone.
