The patient underwent endovenous laser ablation for bilateral GSVs with concomitant phlebectomies. She was discharged on the same day without any reported complications and was prescribed prophylactic low-molecular-weight heparin for 1\u2009week. Seven days later, although asymptomatic, the surveillance DUS confirmed bilateral GSV global occlusion.<\/jats:p>\n               <jats:p>On postoperative day 27, the patient reported sudden-onset dyspnoea, chest pain and presyncope. CT angiography confirmed a pulmonary embolism associated with an area of pulmonary infarction. Further investigation with DUS identified an endothermal heat-induced thrombosis classified as type II.<\/jats:p>\n               <jats:p>The patient was hospitalised for 3\u2009days on therapeutic doses of anticoagulation.
