Inferior Vena Cava Filter Retrieval 23 Month After Implantation With Standard Snare Loop Technique : Case Report

Abstract

1. Introduction. Pulmonary embolism (PE ) and Deep vein thrombosis (DVT ) continues to be a cause of signicant morbidity and mortality which is also third 1 leading cardiovascular cause of death . If not treated properly it also leads to chronic pulmonary hypertension and cor pulmonale . Once DVT is diagnosed treatmet is required and consist of oral anticoagulation and inferior vena cava interruption via lter placement in patients with contraindication for anticoagulation treatment. In 2003 ,the U.S .Food and Drug Administration (FDA ) cleared retrievable inferior vena cave lters (rIVCFs) for clinical use , after that its uses exponentially increases . In parallel with these trends ,there has been growing awareness of device –related complication including fracture , penetration to adjuscent structure , migration , thrombosis and some time embolisation of fractured segment in heart that leads to cardiac 2 3 peforation , arrhythmia and death . In response , the FDA released safety communication in 2010 and 2014 advocating immediate retrieval of 4 lter once mechanical prophylaxis was no longer uses .However retrieval of lter remained rare with rates reported as low as 8.5 %. . Once lter remain in place for long duration, normal standard snare retrieval technique usually not work and alternative techniques like , Sling technique , 5 Excimer laser and Endobronchial forcep supported methods can be used . But prolong duration of lter implantion always associated with less chance of lter retrieval and associated with multiple complication .
