Radiofrequency ablation with concomitant stab phlebectomy increases risk of endovenous heat-induced thrombosis

Concomitant stab phlebectomy and the patient's history of VTE are independent risk factors for EHIT after endovenous ablation with RFA. History of tobacco use and advanced stages of venous disease may also play a role. For patients with these high-risk features, care should be taken to prevent, identify, and treat EHIT early.
