Official Title: New Biomarkers in Post Thrombotic Syndrome

Brief Summary: This 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.

Detailed Summary:

Post-thrombotic syndrome (PTS) is a problem that can develop in nearly half of all patients who experience a deep vein thrombosis (DVT) of lower limbs. PTS symptoms include chronic leg pain, swelling, redness, and skin ulcers. PTS lowers patients' quality of life after DVT, specifically with regards to physical and psychological symptoms and limitations in daily activities. Secondly, the treatment of PTS adds significantly to the cost of treating DVT. PTS also causes lost work productivity: patients with severe PTS and venous ulcers lose up to 2 work days per year Nowadays, there are no effective measures to reduces significatively PTS onset following a DVT episode.

Biomarkers can be of use in further exploring the etiology as well as in developing risk stratification tools for PTS. The relationship between PTS and specific biomarkers may help guide prevention and therapy based on a patient's individual risk profile.

Recent studies showed that MMPs play a significant role in vascular remodeling and endothelial dysfunction and they may explain a role in aneurysm formation as well as in all the clinical manifestations of venous disease (both for acute and chronic related events) but the cellular and molecular mechanisms involved in thrombus resolution and vein wall fibrosis remain undefined.

The presence of MMPs and TIMPs in acute venous occlusion model suggests that there is an important early interplay between protease and inhibitor during events that precede the development of venous disease.

This study aims to deepen the investigators knowledge of PTS and MMPs (and other related molecules such as NGAL and cytokines) to find a predictive molecular system to better classify the risk of patients to develop a PTS after a DVT e
