Pulmonary infarct is the death of lung tissue due to oxygen deprivation.
It is also known as a lung infarct, lung infarction, and pulmonary infarction.
General
- Uncommon because of the dual blood supply (systemic via the bronchial arteries, pulmonary via the pulmonary arteries).
Common causes:[1]
Less common causes:
- Lymphoma, esp. acute promyelocytic leukemia.
- Drugs, e.g. chemotherapy.
- Vasculitis.
- Others.
Gross
- Lung periphery, classically described as wedge-shaped.
Note:
- In a histologic section, the classic wedge-shaped infarct is triangular:
- Base of triangle on the pleural aspect.
- Point furthest from the pleura close to the compromised artery that lead to infarction.
