Target vein recanalization is defined as the postoperative detection of blood flow in a venous segment previously ablated. It can be occurred after thermal-tumescent procedures, as radiofrequency (RFA) and endovenous laser (EVLA) ablation techniques. Despite several papers described and analyzed incidence and consequences of recanalization, limited data are published on risk factors for this condition. The aim of this general review is to investigate clinical and instrumental risk factors for great and small saphenous veins recanalization after RFA, indicating their impact in the follow-up period.


KEY WORDS: Radiofrequency ablation; Great saphenous vein; Small saphenous vein; Risk factors; Venous incompetence
