Persistent abdominal pain caused by an inferior vena cava filter protruding into the duodenum and the aortic wall.

Inferior vena cava (IVC) filter placement has increased dramatically over the past 2 decades. Symptomatic duodenal perforation by IVC filters with involvement of the aorta is a very rare, but challenging, complication. We report a case of persistent atypical right upper quadrant pain secondary to duodenal and aortic perforation by an IVC filter treated with cavotomy for filter removal, primary repair of the duodenum, and extraction of prongs from the aorta.

Excision of a permanent inferior vena cava filter with multiple vena caval perforations.

Perforation of an inferior vena cava filter by one the filter device hooks is a recognized possible complication of this device. We describe a case of surgical excision of a permanent inferior vena cava filter associated with multiple perforations of surrounding structures by each of the 6 hooks of the device. Structures affected include the third lumbar vertebral body, transverse mesocolon, the infrarenal aorta, the duodenum, and the psoas muscle. A thorough understanding of the filter design and adequate preoperative imaging were vital in planning the safe surgical excision of this device.

Endovascular treatment of late aortic perforation due to vena cava filter.

Perforation of inferior vena cava (IVC) by filter struts ranges from 9% to 24%, and clinical sequelae and complications are unpredictable. The aim of this article was to report an unusual case of late complication of IVC filter that caused an IVC wall perforation and penetration of the filter's hooks in the aorta, which was treated by endovascular procedure. Molding strut tip by balloon angioplasty, its accommodation with a bare stent, and its coverage and protection with an endoprosthesis is probably the first technique reported so far in this situation.

Removal of retrievable inferior vena cava filters with computed tomography findings indicating tenting or penetration of the inferior vena cava wall.

To examine the feasibility and safety of removing retrievable inferior vena cava (IVC) filters with struts external to the IVC wall on computed tomography (CT) imaging. This retrospective study included 64 IVC filter retrievals from 62 patients over a 5-year period. CT images obtained before retrieval were used to describe the various imaging characteristics of filter interactions with the IVC wall. Patient medical records were reviewed for filter type, results of filter removal with standard or nonstandard techniques, and complications. Filter struts outside the IVC wall were a common finding on CT with 55 (85.9%) filters showing some degree of perforation. Of 64 filters, 57 (89.1%) were removed successfully; 7 (10.9%) filters could not be removed because of incorporation of filter struts or tip into the IVC wall. Before retrieval, filter fracture was detected in eight (12.5%) cases, and IVC stenosis was present in three (4.7%) cases. No major complications occurred during any retrieval. Two (3.1%) cases were complicated by postprocedure abdominal pain. Both cases clinically resolved, and no abnormalities were detected on postprocedure CT. The appearance of filter struts tenting or penetrating the IVC wall is a common finding on CT performed before filter retrieval. IVC filters with these findings can be removed safely and should not be a contraindication for IVC filter retrieval.
