Inferior vena cava (IVC) filter tilt is a known outcome of IVC filter placement with 15° or greater tilt relative to the long axis of the IVC as a known insertion complication.[1] If this occurs, the general recommendation is for repositioning of the filter at the time of placement. Fifteen degrees or greater tilt is reported to be less effective in preventing pulmonary embolism and may result in a more difficult retrieval. Filter tilt with subsequent embedding of the hook of the filter into the IVC wall is frequently cited for inability to retrieve the filter.[2-7] We present a case of a patient undergoing prophylactic placement of an IVC filter for a total knee arthroplasty with tilting of the filter at placement. This was followed by delays in the patient’s planned surgery as a result of COVID-19 and delayed filter retrieval.
