This paper describes the case of a 75-year-oldfemale with MTS after performing right total knee replacement arthroplasty. The authors diagnosed MTS through intravenous angiographyand angiographic computed tomography on swelling and pain of the left lower extremities after performing right total knee replacementarthroplasty. The thrombus was removed using a thrombolytic agent and mechanical thrombectomy, and an intravenous stent then insertedafter angioplasty.
