The Ideal Deep Venous Thrombosis (DVT) Study
Postthrombotic SyndromeIn the Netherlands, 25.000 patients each year are diagnosed with Deep Venous Thrombosis (DVT). Elastic compression stocking (ECS) therapy reduces the incidence of post thrombotic syndrome (PTS) following DVT from 50% without ECS to 20-30% after ECS therapy for two years. It is however unclear whether all patients benefit to the same extent from this therapy or what the optimal duration of ECS therapy for individual patients should be. ECS therapy is not only costly, inconvenient and demanding but sometimes also even debilitating. Substantial costs could be saved by tailoring therapy to individual needs and as a result the quality of life for individual patients can be expected to improve. This study aims to assess the costs and effects of tailoring the duration of ECS therapy after DVT to individual patients needs. ECS therapy with a standard duration of 24 months will be compared with tailored ECS therapy, following an initial therapeutic period of 6 months, in patients with acute proximal DVT. The primary outcome is the percentage of patients with PTS at two year follow-up. This is a multi-center, randomized, allocation concealed, single-blinded clinical trial.
Pediatric High-Risk Deep Venous Thrombosis Lytic Outcomes Trial
Deep Vein ThrombosisPost-Thrombotic Syndrome1 moreThe purpose of this study is to determine if the use of adjunctive catheter-directed thrombolysis (CDT), which includes the intrathrombus administration of rt-PA (Activase/Alteplase), can prevent post-thrombotic syndrome (PTS) in pediatric patients with symptomatic proximal deep vein thrombosis (DVT) as compared with optimal standard anticoagulation alone.
The SOX Trial: Compression Stockings to Prevent the Post-Thrombotic Syndrome
Deep Venous ThrombosisThe purpose of this study is to determine whether elastic compression stockings used for 2 years are effective in preventing the post-thrombotic syndrome in patients with symptomatic proximal deep venous thrombosis.
Post Thrombotic Syndrome Prevention Study
Post Thrombotic SyndromeDeep Vein ThrombosisThis is a two arm, prospective, single center, randomized clinical trial. Subjects will be randomly assigned into one of two groups using block randomization technique in a 1:1 ratio. The control group will receive care using elastic compression stocking and the intervention group will use the ACTitouch device. Stratified randomization will occur based on whether the Deep Vein Thrombosis (DVT) has iliac or non-iliac involvement. Subjects will be followed for 2 years with clinic visits occurring at 1, 3, 6, 12, and 24 months.
Post-thrombotic Syndrome & Predictors of Recurrence in Catheter-related Thrombosis
Venous ThrombosisNeoplasmsThe goal of the pilot study is to determine if a multicenter prospective cohort study of cancer patients with blood clots associated with catheters is feasible. Cancer patients with catheter-related thrombosis treated with one month of anticoagulation will be evaluated for for post-thrombotic syndrome. Laboratory biomarkers will be evaluated as predictors of recurrent thrombosis.

Post Thrombotic SyndromeDeep Vein Thrombosis1 moreCenters that participated in the HOKUSAI VTE trial will be invited to collect follow of previously enrolled patients at least 2 years after the index VTE.
Physical Activity in Children at Risk of Post-thrombotic Sequelae (PACT)
Post Thrombotic SyndromeDeep Vein Thrombosis'The PACT trial' is randomized pilot trial to demonstrate the feasibility and potential effectiveness of a personal "fitness tracker" to improve adherence to an activity regimen following an initial acute DVT in children.
Treatment of the Postthrombotic Syndrome With the Oblique Stent - TOPOS Study
Post-thrombotic SyndromeIliac Vein Compression SyndromePrimary objective: To assess the efficacy of the stents (sinus-Obliquus stent for the common iliac vein, the sinus-XL Flex stent or sinus-Venous stent for the external iliac and common femoral veins) by evaluating different gradations of patency rates, patient's rating of disease severity and quality of life in patients with post-thrombotic syndrome and concomitant common iliac vein compression. Secondary objective: To assess long-term safety of venous stenting
Compression Hosiery to Avoid Post-Thrombotic Syndrome
Deep Vein ThrombosisDeep Vein Thrombosis Leg1 morePatients with a deep vein thrombosis (DVT) may develop long-term symptoms, e.g. lifelong leg pain, skin changes and occasionally ulceration, known as post-thrombotic syndrome (PTS). This affects about half of people with a history of DVT. This randomised study aims to show whether the regular use of a compression stocking after DVT in the leg, prevents long-term pain, swelling and ulceration. Currently small trials show varied results and a large trial is required to answer the question.
Biomarkers in Post Thrombotic Syndrome
Postthrombotic Syndrome With Ulcer of Left Lower ExtremityExtracellular Matrix AlterationThis study aims to deepen the investigators knowledge of Post Thrombotic Syndrome and MMPs (and other related molecules such as TIMPS, NGAL and cytokines) to find a predictive molecular system to better classify the risk of patients to develop a PTS after a DVT episode, in order to monitorate more strictly the patients at high risk for developing this complication.
