Factors Associated with Recanalization and Reintervention Following Below-knee Polidocanol Endovenous Microfoam Ablation for Great Saphenous and Small Saphenous Veins

Polidocanol endovenous microfoam (PEM) has been used to treat lower extremity venous reflux for almost a decade with specific advantage in below-knee (BK) truncal veins where thermal ablation poses a risk for injury to adjacent nerves. Current literature in the BK segment often examines short-term outcomes with modest sample sizes. We aim to identify factors associated with recanalization and reintervention in this subset of patients.
