(a) Contrast-enhanced computed tomography (CT) demonstrated nonobstructive thrombus (arrows) with air density extending from the CVC via the right femoral vein to the suprarenal IVC, just above the renal vein confluence. (b) Follow-up CT established that there was no IVC thrombus or thrombus in the filter.

Contrast-enhanced computed tomography (CE-CT) demonstrated pneumonia, pleural effusion, pulmonary atelectasis, and nonobstructive thrombus with air density extending from the CVC via the right femoral vein to the suprarenal IVC, just above the renal vein confluence (Figure 1(a)).
A transient IVC filter was implanted at the site of the suprarenal IVC via the right jugular vein. Insertion of the IVC filter was performed under angiographic and echocardiographic guidance.

IVC filter (Gunther Tulip Vena Cava Filter, Cook, Bloomington, IN) was implanted at the site of the suprarenal IVC via the right jugular vein. Insertion of the IVC filter was performed under angiographic and echocardiographic guidance (Figure 2).
Thrombi caught in the IVC filter were aspirated using a 7-Fr sheath and a 50 mL syringe via the right femoral vein. Many thrombi were removed by the aspiration thrombectomy.
