Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease that obstructively remodels the pulmonary arteries of large and small caliber as a consequence of an important pulmonary embolism (PE). It is believed to have an accumulated incidence of 0.1 to 9.1% in the first 2 years after a symptomatic event of PE. The large margin of error among the authors offering these numbers is probably due to the reference bias, the shortage of early symptoms, and the difficulty of differentiating acute PE from the symptoms of pre-existing CTEPH. Although its exact prevalence and annual incidence are unknown, some data suggest that this condition can occur in approximately 5 individuals per million inhabitants per year. In the differential diagnosis of the same, must take into account different conditions very different from the thrombotic phenomena. These conditions include pulmonary artery sarcoma, tumor cell embolism, parasites (such as hydatid cyst), foreign body embolism, and congenital or acquired pulmonary artery stenosis. All this makes the diagnosis difficult and affects consecutively the prognosis of this disease. This review aims to interpret the diagnostic methodology currently used in the CTEPH and define the different prognostic situations of it.
