An unopened titanium Greenfield IVC filter: intravascular ultrasound to reveal associated thrombus and aid in filter opening

A titanium Greenfield filter did not open following placement in the infrarenal inferior vena cava (IVC). Abdominal radiograph and cavogram showed no definite reason for filter malfunction. Intravascular ultrasound (IVUS) demonstrated the unopened filter in the IVC with thrombus binding the legs. Th...

Zusammenfassung:	A titanium Greenfield filter did not open following placement in the infrarenal inferior vena cava (IVC). Abdominal radiograph and cavogram showed no definite reason for filter malfunction. Intravascular ultrasound (IVUS) demonstrated the unopened filter in the IVC with thrombus binding the legs. The thrombus was disrupted with a catheter, and the filter completely expanded with a balloon. IVUS documented full-filter opening in addition to residual thrombus in the filter following manipulation.
