IVC filter which is no longer needed
Why it’s done:
IVC filters can be protective against pulmonary embolism, but can also cause long-term complications such as thrombosis, fracture or migration. Thus, it is preferable to remove IVC filters which are no longer needed.
How it’s done:
An interventional radiologist uses ultrasound to access the jugular vein at the neck. A snare is used to engage the hook at the top of the filter, and a sheath is passed over the filter to collapse and remove it. Sometimes more advanced maneuvers are required for filter removal.
Level of anesthesia:
Conscious sedation or general anesthesia
Bleeding, IVC thrombosis, infection
Two to three hours of bed rest, then discharge home the same day
