Wells score for pulmonary embolism

The Wells score for pulmonary embolism has been shown to be related to the probability of pulmonary embolism, and plays an important role in the guidelines for its management. In the event of clinical suspicion, a low Wells score (or intermediate score, depending on the case) should lead to a D-dimer assay. A high (or intermediate, depending on the case) Wells score should be followed by a thoracic angio-CT-scan (or lung scan) without D-dimer measurement, or independently of their value if they have already been measured.
