(A and B) The enhanced abdominal CT demonstrated huge retroperitoneal hematoma anterior to the abdominal aorta and adjacent to the filter within the lumen of IVC. (C) The angiography revealed extravasation of contrast medium from the right third lumbar artery due to penetration of the wall caused by the hook of the IVC filter. (D) Coils were deployed in the lumbar artery and post procedural angiogram showed no overflow of the contrast medium. (E) Coils in the artery below the IVC filter were observed on the abdominal CT scan with enhancement. No extravasation of contrast medium was revealed. CT = computed tomography, IVC = inferior vena cava.

Contrast-enhanced CT at the local hospital showed a massive retroperitoneal hematoma adjacent to the IVC filter (Fig. 1A and B). Extravasation of contrast medium from the right third lumbar artery was observed (Fig. 1C). The second lumbar artery was also occluded with coils (MWCE-18-2.2-2-HILAL x 1, Hilal Embolization Microcoil; Cook Medical Inc) to prevent formation of a collateral circulation (Fig. 1D). Several days later, she recovered with hematoma shrinking in size (Fig. 1E) and was discharged from the hospital without any symptoms.
