Tromboembolismo pulmonar discordante

The pulmonary thromboembolism (PET) is always a medical emergency. If there is a doubt with the diagnosis, it is important not to delay hospitalisation and treatment. It is a frequently under-diagnosed condition, with high morbidity and mortality. Its real incidence is not well established, due to its clinical variability, as well as the difficulties in diagnosing it. Owing to its high morbidity, this pathology is a major socioeconomic and cost for health care services.
