To the Editor,
Inferior vena cava (IVC) filters are recommended in patients with extensive lower extremity thromboembolism with contraindications to anticoagulation, including visceral bleeding, trauma, elective surgery and pregnancy. There is an increase in the complication rates on attempted filter retrieval beyond the recommended time frame of indwelling filters, which include failure of retrieval, device infection, IVC filter fracture and migration, thrombus formation, and IVC occlusion and perforation . Hence, the British Society of Radiologists (BSIR) and United States Food and Drug Administration (US-FDA) have issued guidelines that recommend retrieval of temporary IVC filters in all patients within 9 weeks . However, there is global evidence of poor temporary IVC retrieval rates, with means ranging from as low as 8 to 45% . The main recurring causes remain poor patient follow-up following IVC filter insertion, lack of awareness and education amongst the referring...
