A 55-year-old man developed deep venous thrombosis and inferior vena cava (IVC) thrombosis 7 years earlier and was treated by placement of a permanent IVC filter.One week ago,he was admitted with bilateral lower limb swelling and pain.Digital subtraction angiography showed a filling defect above the original filter.A retrievable Tulip filter was placed and catheter-directed thrombolysis was performed.Six days later,the patient experienced sudden,persistent upper right abdominal pain,and a computed tomography scan revealed the formation of retroperitoneal hematoma.Symptomatic treatments were administered,and the hematoma gradually resolved during follow-up.
