Chronic Venous Thrombosis: Relief with Adjunctive Catheter-Directed Therapy (C-TRACT)
C-TRACT (Chronic Venous Thrombosis: Relief with Adjunctive Catheter-Directed Therapy) is a multicenter, randomized trial led by Suresh Vedantham, MD, FSIR, of the Mallinckrodt Institute of Radiology, Washington University in St. Louis. It is funded by the National Heart, Lung and Blood Institute (NHLBI) within the National Institutes of Health (NIH). The study goal is to determine if the use of image-guided endovascular therapy (EVT) is an effective strategy to reduce the severity of post-thrombotic syndrome (PTS) and improve quality of life (QOL) in patients with established disabling iliac-obstructive post-thrombotic syndrome (DIO-PTS).
The study is planning to enroll approximately 374 subjects at 20–40 clinical centers. All subjects will be asked to return for follow-up visits at 2, 4, 6, 12, 18, and 24 months post-randomization. Patient eligibility can be found in the protocol synopsis.
SIR Foundation encourages SIR members to participate in this important effort to support evidence-based IR care by serving as site investigators or by referring patients to study sites.
C-TRACT is planning to recruit between 20–40 clinical centers, which are selected based on site selection criteria. Interested sites are required to complete and submit the C-TRACT Study Site Questionnaire.
C-TRACT will enroll approximately 374 subjects. To reach this enrollment goal, an innovative mobile application was developed to refer potential patients to participating sites. The C-TRACT Referral Tool app is designed to help physicians submit patient referrals securely and conveniently. The C-TRACT referral tool app can be downloaded to your mobile device.
