Is Cook celect IVC filter MRI safe?
Nonclinical testing has demonstrated that the Cook Celect Platinum Filter is MR Conditional. A patient with this device may be safely scanned in an MR system meeting the following conditions: Static magnetic field of 1.5 Tesla or 3.0 Tesla only.
Can you have an MRI with a Greenfield filter?
They conclude that, while most Greenfield filters respond to a magnetic field, the chance of migration of a filter because of an MRI scan is small. Therefore, MRI scanning of patients with Greenfield filters has little risk.
What is the size of an IVC filter?
The TrapEase filter is 65 mm in length before deployment and 50 mm in length when expanded maximally to a diameter of 35 mm. The design allows placement in IVCs with diameters ranging from 18 to 30 mm. (See the following image.) If appropriate, the catheter can be removed endoscopically.
What is an IVC filter used for?
An inferior vena cava (IVC) filter is a small device that can stop blood clots from going up into the lungs.
What are the different types of IVC filters?
There are two general types of IVC filters currently available in the United States: permanent and optional (or retrievable). Permanent filters have been used since the 1970s and are placed in patients with a long-term need for mechanical prophylaxis against PE and absolute contraindications to anticoagulation.
Can you have an MRI with a vena cava filter?
Most manufacturers make their inferior vena cava (IVC) filters of non-ferromagnetic materials, meaning IVC filters are typically MRI safe. Even in filters that include some weakly ferromagnetic materials, it only takes a few weeks for the tissue growth around the filter to secure it firmly to the vein wall.
Can you still get PE with IVC filter?
For permanent filters, research has shown that breakthrough PE—despite the IVC filter—occurred in 0% to 6.2% of cases. One randomized controlled trial 10 showed that PE occurred in 15.1% of high-risk patients who did not receive IVC filters.
