Abstract:
A 50 year-old man with no significant medical history was admitted for dyspnea and left femoral swelling. Contrast-enhanced computed tomography revealed pulmonary thromboembolism (PTE) and a thrombus in the inferior vena cava (IVC). The thrombus extended from the proximal IVC to the left popliteal vein. Therefore, we decided that an IVC filter insertion was difficult to indicate. Urgent IVC and peripheral vein thrombectomy was performed under cardiopulmonary bypass. On postoperative day 1, venous ultrasonography showed residual deep vein thrombosis in the left external iliac-femoral vein and the popliteal vein. The IVC filter insertion was performed to prevent the recurrence of PTE.
