Update on the Titanium Greenfield Filter and Recommendations for Insertion

Mary C. Proctor, M.S.

The original stainless steel Greenfield filter was designed for operative insertion, and when percutaneous techniques became available, a titanium model of the filter was developed to allow it to be inserted through a 14 French sheath. From the filter registry of 783 TGF devices from 1989 to 1996, we have follow-up of 373 patients, which is the majority of those still alive 1 year following placement. The long-term caval patency rate was 97.6%, and there was protection against recurrent embolism in 97% of patients with only 2.9% documented or suspected recurrent embolism rate. Therefore, the device has met the standards established by the stainless steel filter, and has enabled patients to enjoy long-term protection without the added risk of vena caval obstruction.

Key Words: Venous thromboembolism • vena caval filters
