IVC Filter Removal Technique: A Case Report and Systemic Review of the Hangman’s Wire Loop Technique

Abstract

Venous thromboembolism (VTE), which encompasses both deep vein thrombosis (DVT) and pulmonary embolism (PE), may lead to a fatal outcome. Such patients may also have contraindications to commencing anticoagulation due to reasons such as recent brain surgery, recent trauma or recent UGIB. To mitigate this risk, Inferior Vena Cava (IVC) filters have become an important tool in the prevention of VTE. In peculiar situation, the placed IVC filter may not necessarily stay in place and may be tilted. The tilted filter causes intimal hyperplasia tissue over its hook, thus preventing capture of the hook by standard techniques. We presented a case of embedded IVC filter within caval wall of a 77 years old female with right lower limb DVT, which was removed using centering technique.
