The diagnosis of pulmonary embolism is based on several distinct steps. Faced with the suspicion of pulmonary embolism, we are led to use a clinical probability score to guide the rest of the examinations. Revised Geneva score and the Wells score are the two best validated scores. They identify low-, medium-, and high-risk patients in a simple way. The third step, if the clinical probability is not high, is to assay the D-dimers. A negative result excludes pulmonary embolism with a negative predictive value close to 100%. The last step, if they are positive, is the chest angiography-computed tomography (CT) scan that can rule out or confirm pulmonary embolism and to search for severity signs. |
