This report summarizes the Internet discussion on Post Ablation Superficial Thrombus Extension (PASTE) from the great saphenous vein (GSV) into the common femoral vein as a consequence of endovenous treatment of the GSV with laser or radiofrequency, and represents the collective work of the Laser-Floating Group. The Vasculab group moderated the Internet discussion. The PASTE entity was discovered thanks to the follow-up examination with duplex ultrasound in the immediate post-treatment period. The thrombi are apparent on ultrasound within 3-7 days of treatment, are non-occlusive and asymptomatic and are rarely identifiable after 14 days. They caused neither venous obstruction, nor symptomatic pulmonary embolism. Anticoagulant treatment was used at the beginning, but the experience showed that the course was usually benign, harmless and asymptomatic; therefore, it seems that no therapy, only observation is needed in these cases.
