Pulmonary Embolism: Pulmonary Contrast Angiogram

Pulmonary embolism (PE) is a fatal clinical condition that occurs as a result of mechanical obstruction of the pulmonary artery or its branches by any material (such as thrombus, air or fat) from anywhere in the body. Pulmonary embolism can be an acute condition, in which the signs and symptoms develop immediately after the event (i.e., the obstruction of the pulmonary vessels), or it can be chronic, in which the signs and symptoms develop progressively for years. In this article, you will be able to understand the definition, incidence, pathophysiology, risk factors, symptoms and signs and the prognosis of pulmonary embolism.
