[Temporary placement of inferior vena cava filter prior to transcatheter arterial embolization (TAE) for hepatocellular carcinoma with IVC tumor thrombus--prevention of pulmonary tumor emboli after TAE].
A 66-year-old-man with a right huge hepatocellular carcinoma (HCC) extending into both the right portal vein and the right atrium underwent transcatheter arterial embolization (TAE) via the right hepatic artery. Prior to the TAE, a temporary inferior vena cava (IVC) filter was placed suprarenally for prevention of pulmonary tumor emboli. When we replaced the temporary IVC filter with a new one 7 days after the TAE, the filter which was pulled out of the IVC captured a fragment of the tumor thrombus. A histopathological specimen demonstrated only ghost cells. The patient has been followed at our outpatient clinic without any tumor thrombus or pulmonary infarction for 13 months after this procedure.
