Pulmonary infarction - Definition

Ask a question


Pulmonary infarction is the destruction of lung cells following a stopage of blood circulation. This infarction is the consequence of the blockage of an artery that irrigates lung tissue. The pulmonary infarction is a rare complication of a pulmonary embolism. Concretely, this means that a clot has migrated from another area of the body (usually the legs) into a pulmonary artery, where it is blocked. Clinical signs are typically coughing up black blood, chest pain, and dry cough leading us to suspect a pulmonary embolism.
