| Summary: | Abstract Background Although thrombosis complication is rare after arthroscopic meniscus surgery, deep vein thrombosis and pulmonary embolism can be fatal. The associated risk factors and whether anticoagulant prevention after arthroscopic knee surgery is necessary have not reach consensus. Here we present a case of deep vein thrombosis and pulmonary embolism after a common arthroscopic meniscectomy. Case presentation The patient had no risk factors except ipsilateral leg varicose veins. She present swell at knee and calf from postoperative 3 weeks, and developed dyspnea, palpitation, and nausea on 33th day, pulmonary embolism was confirmed with CT angiography at emergency department. After thrombolysis and anticoagulation therapy were administered, the patient improved well and discharged. And the intravenous ultrasound confirmed thrombosis of popliteal vein and small saphenous vein. Who don’t have common risk factors for venous thromboembolism. Conclusions Despite the low incidence of thromboembolic complications after simple arthroscopy surgery, its life-threatening and devastating property make clinicians rethink the necessity of thromboprophylaxis and importance of preoperative relative risk factors screening.
