Abstract
A previously healthy 70-year-old woman underwent cyanoacrylate closure of an incompetent left small saphenous vein. Six days later, grade 2 treatment-induced thrombosis occurred at the sapheno-popliteal junction. Three days later, the patient presented with pale, cold pain in the left lower extremity. Diffuse thrombosis of the left lower extremity involved the small and great saphenous and deep veins. The patient was admitted and immediately administered heparin with anticoagulant factors, with symptoms began resolving 1 d later. The superficial vein thrombi were resolved. Although a deep venous thrombus remained, symptoms disappeared, and the patient was discharged.
