Abstract
We experienced a case of idiopathic thrombosis of the inferior vena cava (IVC) which was incidentally detected by CT scan.
A 45-year-old man was admitted to the hospital for treatment of hepatitis C and was incidentally found having an asymptomatic thrombosis of IVC. No anomalies were found in other abdominal organs, and he had no previous history of injury. No abnormalities in the blood coagulation system were also shown. Local resection and plasty of IVC were performed to prevent pulmonary embolism. During surgery a belt-like thrombus about 10 cm in length was found at the dosal side of IVC beneath the renal vein. The resected specimen revealed a white thrombus alone without other findings including foreign body. It was concluded that the thrombosis in this case was idiopathic. In this paper briefly describes the case and presents some notes on the probable etiology of the thrombosis formation and treatment, as well as a review of the literature.
