Retrievable inferior vena cava (IVC) filters - serious complications associated with attempted IVC filter retrieval

(All models and manufacturers) Be aware of the various maximum implant durations for safe retrieval for each IVC filter model. (MDA/2013/028)

CAS deadlines

Action underway: 10 May 2013, action complete: 24 May 2013

Note: These deadlines are for systems to be in place to take actions and not for the completion of patient follow-up and testing.

Device

Retrievable inferior vena cava (IVC) filters.

All models and manufacturers.

Problem

Serious complications associated with attempted IVC filter retrieval.

This MDA updates and replaces MDA/2007/029 ‘Retrievable permanent inferior vena cava (IVC) filters’.

The option to retrieve certain IVC filter models when no longer needed has only become available within the last 10 years. The MHRA has received relatively few adverse incident reports, but is aware of a high prevalence of retrieval related complications, through published papers and anecdotal reports. For example complications have arisen during attempted retrieval of filters with massive trapped thrombus, or which have undergone significant tilting, caval wall penetration, or loss of structural integrity while in situ. It is therefore important that, immediately prior to filter removal, the patient undergoes a venogram which is reviewed to enable an up-to-date assessment of the risks and benefits associated with the procedure.

It is also important to ensure that adequate systems are put in place to minimise the risk of patients being lost to follow-up.

The MHRA reminds clinicians of the importance of reporting problems that they encounter with these devices, so that we can monitor device performance. We would appreciate feedback on experience of any negative short or long term outcomes, including cases where the device could not be retrieved, despite being within its labelled implant duration for doing so.

This Medical Device Alert has been prepared in consultation with the BSIR (British Society of Interventional Radiology) and is intended to complement any broader guidance which the BSIR may issue, on the safe implantation and retrieval of these devices.

Action

Be aware of the various maximum implant durations for safe retrieval for each IVC filter model. The relevant clinical evidence and advice can be found in the manufacturer’s instructions for use.

Ensure patients are fully aware of the importance of attending future assessments, to reduce the number lost to follow-up.

Retrieve the device as soon as possible once it is no longer clinically required.

Consider, and ideally schedule, the retrieval date at the time of implantation.

Base the decision on the filter’s suitability for retrieval on a thorough implant assessment, including venography immediately prior to attempted retrieval. Be aware that some retrievable filters become unsafe to remove due to progressive changes in their position, condition, orientation or thrombus within the filter.

Report all adverse events associated with the use of these devices to the manufacturer and the MHRA.

Action by

All physicians who insert IVC filters.
