A longitudinal single-center cohort study on the prevalence and risk of accessory saphenous vein reflux after radiofrequency segmental thermal ablation of great saphenous veins

Whereas posterior ASVs were meaningless, refluxing anterior ASVs occurred in a significant proportion of legs after thermal ablation of GSVs. Whether nonrefluxing anterior ASVs should be treated at the time of GSV ablation needs further examination.
