Inferior vena cava (IVC) filter is an important therapeutic device used in the management of venous thrombo-embolism (VTE) in patients that are contra-indicated for anti-coagulation therapy. While there has been significant increase in the use of filters , unfortunately there are no standardized collection of data to track, compare outcomes, report safety and efficacy.

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: IVC Filter Study to Monitor and Measure Patients Outcomes Through Standardized Collection and Analysis of Clinical Information

Further study details as provided by American Venous Forum:

Primary Outcome Measures:
  • Integrity of IVC Filter 12 months post placement [ Time Frame: 48 Months ]

Enrollment: 20000
Study Start Date: May 2011
Estimated Study Completion Date: May 2014
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Detailed Description:

The registry is a multi-institutional bioinformatics database for the collection of data relevant to Inferior vena cava filters. Participating study centers may enroll patients and enter data in the web-based registry that include demographics, clinical features, management details and follow-up up to 48 months.

The purpose of this study is to improve our understanding of the retrieval rate, long term safety and efficacy on IVC filters placed in North America.
