Context: Use of inferior vena cava filters (IVCFs) is associated with complications which can be minimized by early follow-up and retrieval. Aim: The aim of this study was to document types of retrievable IVCFs, complications after placement, and how to prevent them. Settings and Design: Institutional ethics committee approval was obtained to perform a retrospective review of hospital medical records for all patients who had an IVCF placed between Jan 2003 and Oct 2013. Patients and Methods: Retrospective data were collected from the picture communicating and archiving system radiology database. Patients' records and radiological imaging were reviewed. Data extracted included patient demographics, indications for inferior vena cava (IVC) placement, filter retrieval, follow-up, and complications namely IVC perforation, filter fracture, filter migration, and filter embolization. Statistical Analysis Used: The data collected were analyzed using SPSS version 21. The output data were summarized using tables and graphs as shown below. Results: A total of 182 patients (93 males) and (89 females) had retrievable IVCFs inserted. The most common indication for filter insertion (56.59%) was venous thromboembolism and contraindication to anticoagulation. Retrieval rate was 42.85%. Procedural success was achieved in 78 of 85 attempted filter retrievals (91.76%). Fourteen patients (7.69%) had IVCF related complications. Conclusion: Timely follow-up increases the likelihood of successful retrieval of optional IVCFs and reduces potential complications.
