title: Case of the disappearing heat-induced thrombus causing pulmonary embolism during ultrasound evaluation.
abstract: We report a case of a 58-year-old male patient who underwent successful endovenous radiofrequency ablation of the left great saphenous vein for CEAP class 4a venous disease. On the third postoperative day, he had a duplex ultrasound scan for evaluation which showed successful occlusion of the great saphenous vein (GSV) with class 2 endovenous heat-induced thrombus (EHIT) that disappeared during the evaluation and caused a pulmonary embolism. To our knowledge, no case of pulmonary embolism has been reported to occur during postoperative follow-up duplex scanning. Relevant literature is reviewed and a possible mechanism for thrombus dislodgement is entertained.
