Summary

An 85-year-old female with DVT and PE underwent permanent IVC filter placement, which was accidentally deployed in the ovarian vein. Successful retrieval and reimplantation were performed. This case highlights the necessity of precise imaging guidance and contingency planning for filter malposition.

Introduction

IVC filters are widely used for pulmonary embolism prophylaxis, but malposition (e.g., ovarian vein deployment) is rare and life-threatening. This case emphasizes procedural precision and rescue strategies for filter complications.

Case analysis

Clinical Profile: Lower limb swelling, PE, and peritoneal tumor on CT.

Error: Filter misplaced in ovarian vein via transfemoral approach.

Management: Interventional retrieval and correct IVC reimplantation.

Outcome: No recurrent PE; tumor managed with chemotherapy.

Conclusion 

IVC filter placement requires meticulous imaging guidance. Interventional retrieval should be prioritized for malposition. Multidisciplinary collaboration is recommended for complex cases.
