Type II endoleak is a common complication following endovascular aortic aneurysm repair and can lead to an increased risk of aneurysmal expansion and rupture. The most frequently employed strategies to treat Type II endoleak involves catheterization of the branch vessels responsible for the endoleak or accessing the aneurysm sac through a percutaneous approach. An endovascular transcaval approach for embolization of the aneurysmal sac provides an alternate strategy with comparable success rates. This technique is advantageous when the endoleak is predominantly on the right side of the aneurysm sac and/or when a direct access to the aneurysm sac through a percutaneous approach is not feasible.
Objective: Over the last 2 decades, there has been an exponential rise in placement of retrievable inferior vena cava (IVC) filters, while the retrieval rate has remained steadily low. Approaches to increasing filter retrieval rates have been extensively studied. Conclusion: This review presents an up-to-date review of reported data-driven variables that affect retrieval rates of IVC filters, with a focus on clinical, technical, and process factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
