Blood Clot Study

Chronic Venous Thrombosis: Relief with Adjunctive Catheter-Directed Therapy (C-TRACT)

This study is currently closed to enrollment.


Scanning electron micrograph of a blood clot in human blood
AGE: >18 years old
TYPE: Observational and sample collection
CONDITION: Deep Vein Thrombosis (DVT), Post Thrombotic Syndrome (PTS)

Study Purpose

The purpose of this study is to examine what the best treatment is for damage caused deep vein thrombosis (DVT). This damage can lead to a condition called Post Thrombotic Syndrome (PTS). In this study, patients with moderate to severe PTS will be randomized to either endovascular therapy (EVT) or no-EVT treatment groups. All study patients will be monitored closely and undergo optimal medical/compression and wound care as part of their treatments. The EVT arm patients will additionally be treated with advanced image-guided procedures that are currently used in standard practice. The study aims to understand which treatment strategy is most effective in improving patients’ symptoms, healing wounds and improve quality of life.
