Lung infarction

Lung Infarction

Lung infarction (pronunciation: /lʌŋ ɪnˈfɑːrkʃən/), also known as pulmonary infarction, is a serious medical condition characterized by the death of a section of lung tissue due to a disruption in its blood supply.

Etymology

The term "infarction" is derived from the Latin "infarcire", meaning "to stuff into". In medical terminology, it refers to the process of tissue death due to lack of oxygen supply, which is often a result of blockage in the blood vessels supplying the tissue.

Causes

The primary cause of lung infarction is pulmonary embolism, a condition where one or more arteries in the lungs become blocked, typically by blood clots. Other causes can include conditions that affect blood clotting, such as deep vein thrombosis and certain heart diseases.

Symptoms

Symptoms of lung infarction can include chest pain, coughing up blood, shortness of breath, and other symptoms similar to those of a heart attack.

Diagnosis

Diagnosis of lung infarction typically involves imaging tests such as a CT scan or a ventilation/perfusion scan, and blood tests to check for elevated levels of certain substances that can indicate a blood clot.

Treatment

Treatment for lung infarction primarily involves addressing the underlying cause, such as treating a pulmonary embolism or managing a clotting disorder. This can involve medications, procedures to remove or dissolve clots, and in severe cases, surgery.
