Comparative study on risk factors and early outcome of symptomatic distal versus proximal deep vein thrombosis: results from the OPTIMEV study.

There is a lack of consensus on the value of detecting and treating symptomatic isolated distal deep-vein thrombosis (DVT) of the lower limbs. In our study, we compared the risk factors and outcomes in patients with isolated symptomatic distal DVT with those with proximal symptomatic DVT. We analysed the data of patients with objectively confirmed symptomatic isolated DVT enrolled in the national (France), multicenter, prospective OPTIMEV study.

Ascribing leg symptoms to chronic venous disorders: the construction of a diagnostic score.

Objectives: The goal was to create a simple diagnostic scoring system able to differentiate leg symptoms related to chronic venous disorders (CVD) from those produced by other causes.

Methods: A prospective observational study was done of ambulatory or hospitalized patients from 13 private and five institutional vascular centers. Two groups of patients with leg symptoms were investigated.
