Prof. Michael Lee has issued an open invitation as Primary Investigator to members of the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) to commence a registry that will assess the success of caval filter retrieval. Says Lee: "There is a dear th of information in the literature regarding filter retrieval at present. CIRSE has therefore organised this registry, which it believes is an impor tant project and we very much hope that you will support it."
Furthermore, while the primary end point of the registry is to assess the success of filter retrieval among the different filter types, the secondary end points include assessing complications during retrieval and dwell time of different filter types.
All CIRSE members are invited to participate. The registry will run for twelve months and it is hoped to obtain data on at least five hundred filter retrieval procedures. Authorship on the final paper will depend on the number of filter retrievals entered in the registry. The five largest contributors will become authors.
