Abstract
BackgroundReasons for the variation in response of deep vein thrombosis (DVT) to anticoagulation treatment are not known. Some patients develop complications such as post-thrombotic syndrome or recurrent DVT but others make a full recovery. The aim of the study is to identify the level of variation in response to anticoagulation treatment and provide more precise and quantitative disease characterisation in response to treatment.MethodsA prospective observational study using duplex ultrasound to examine changes in thrombus characterisation, evolution and resolution over a 2 year period in patients with a confirmed DVT. Logistic regression analysis will be used to seek associations between characteristics present at baseline and the outcomes of DVT resolution, recurrence and the development of post-thrombotic syndrome (PTS).DiscussionThis research into the response to treatment of lower limb DVT and predictive factors for DVT resolution, recurrence and PTS could inform a more tailored approach to anticoagulation therapy for the future management of DVT.UKCRN ID: 16016.

Highlights
Reasons for the variation in response of deep vein thrombosis (DVT) to anticoagulation treatment are not known
Some thromboses may resolve before the course of anticoagulation treatment is completed and some may not be resolved upon completion of the treatment cycle
Clinical ultrasound imaging is not routinely used on completion of the course of anticoagulation treatment to establish the status of the thrombosis or residual venous function
Summary
A prospective observational study using duplex ultrasound to examine changes in thrombus characterisation, evolution and resolution over a 2 year period in patients with a confirmed DVT. Logistic regression analysis will be used to seek associations between characteristics present at baseline and the outcomes of DVT resolution, recurrence and the development of post-thrombotic syndrome (PTS)
