Insights
Inferior vena cava (IVC) filter placement is rising. A new generation filter uniquely penetrated the IVC, causing retroperitoneal hemorrhage in an anticoagulated patient, highlighting a rare complication.
Area of Science:
- Vascular surgery
- Interventional radiology
- Cardiology
Background:
- Inferior vena cava (IVC) filter placement is increasingly common for pulmonary embolism (PE) prophylaxis.
- Utilization is driven by trauma cases, temporary filter approval, and perceived low complication rates of new designs.
Purpose of the Study:
- To report a unique case of IVC penetration by a new generation filter.
- To highlight a rare but serious complication associated with IVC filter placement.
Main Methods:
- Case report presentation.
- Review of clinical course and imaging findings.
Main Results:
- A new generation IVC filter uniquely penetrated the IVC wall.
- This resulted in a significant retroperitoneal hemorrhage.
- The patient was fully anticoagulated at the time of the event.
Conclusions:
- IVC filter penetration is a rare complication.
- New generation filters, despite perceived low risks, can cause severe adverse events.
- Vigilance and careful patient selection are crucial during IVC filter placement.
Abstract:
Placement of inferior vena cava (IVC) filters is an increasingly common request at our institution. The rise in utilization of caval filtration is probably multifactorial and includes pulmonary embolism (PE) prophylaxis most notably in the setting of trauma, the approval and widespread use of temporary/removable filters, and the perceived low complication rates associated with new generation filter designs. We present a unique case of IVC penetration by a new generation filter that resulted in a retroperitoneal hemorrhage in a fully anticoagulated patient.
