Complications Associated With Inferior Vena Cava Filter Retrieval: A Systematic Review.

Abstract

Inferior vena cava (IVC) filters have been used successfully in high-risk patients to prevent thromboembolism. The filters are widely created as retrievable devices, but complication rates progressively increase during IVC filter retrieval. This study aims to analyze IVC filter retrieval cases and associated complications during and following the procedures regarding dwell times, specific filter types, filter positioning, and advanced retrieval techniques.This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to select and analyze relevant articles. A literature search for articles was performed on September 23, 2023, through three research databases: PubMed, ProQuest, and ScienceDirect. The keywords used to identify relevant publications were "IVC Filter retrieval AND complications" and "IVC filter removal AND complications". The articles before 2012 were excluded. Relevant articles were selected based on the inclusion and exclusion criteria. In total, 20,435 articles were found: 812 from PubMed, 15,635 from ProQuest, and 3,988 from Science Direct. Among the exclusions were 18,462 articles, which were excluded in the automatic screening process, leaving 1,973 for manual screening. The manual screening of articles was conducted based on title, abstract, article type, duplicates, and case reports, where 1,918 articles were excluded. Ultimately, 55 articles were included in this review. This study demonstrates that IVC filter retrievals have significant complication rates. Many complications have a common theme: prolonged dwell time and lost follow-up appointments. Therefore, importance should be placed on patient education and implementing strict protocols regarding the timelines of IVC filter removals.
