A randomized controlled study to evaluate the safety and feasibility of concomitant transluminal injection of foam sclerosant combined with endovenous laser ablation in patients with incompetent small saphenous veins
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.
