Fracture and Embolization of an Inferior Vena Cava Filter
Strut Leading to Cardiac Tamponade

A
56-year-old woman presented to the Emergency Department of Parkland Memorial Hospital complaining of
chest pain. She had a remote history of a hemorrhagic
cerebrovascular accident complicated by pulmonary embolism, for which a Gunther-Tulip inferior vena cava (IVC)
filter had been placed 6 years previously. In the triage area,
the patient collapsed and was found to be hypotensive. An
ECG showed sinus bradycardia with nonspecific ST and
T-wave changes (Figure 1). Bedside echocardiography demonstrated a moderate-sized pericardial effusion with evidence
of cardiac tamponade. A pericardiocentesis was performed
with removal of 25 mL of blood, and the patient’s vital signs
stabilized. A portable chest x-ray suggested a foreign body
just above the left hemidiaphragm (Figure 2), which was
confirmed by computed tomographic (CT) scan of the chest,
which revealed a linear metallic foreign body in the left
anterior pericardium adjacent to the right ventricle (Figure 3).
On the abdominal CT scan, one of the struts from the
patient’s IVC filter was not visualized with the remainder of
the IVC filter (Figure 4). The patient was taken to the
operating room, where exploration of the pericardial space
demonstrated a small laceration of the right ventricular free
wall (Figure 5) and a linear 3-cm metallic foreign body
(Figure 6) consistent with the missing IVC filter strut. The
patient recovered uneventfully from surgery. IVC strut fracture occurs in fewer than 5% of cases,1,2 and embolization has
been reported as a rare complication of strut fracture.3
