Common causes of hemoptysis include lung cancer, tuberculosis, lung abscess, and bronchiectasis. Rare causes include pulmonary isolation disease, pulmonary arteriovenous malformation, pulmonary aneurysm, and pulmonary vasculitis. Most hemoptysis can be stopped with hemostatic medication, but in some cases, the hemoptysis is large or recurrent and may cause anemia, shock, and in severe cases, asphyxia and death due to hemoptysis. For recurrent hemoptysis or hemoptysis (bleeding greater than 400 ml in 24 hours) that cannot be immediately relieved by surgery because of the failure of aggressive conservative medical treatment, interventional therapy is a better treatment option. Most hemoptysis originates from branches of the bronchial arteries, so bronchial artery embolization can rapidly control the bleeding, and the procedure is similar to that of bronchial artery perfusion chemotherapy. In patients with hemoptysis in which no lesion is found on bronchial arteriography, the possibility of pulmonary artery hemorrhage should be considered and pulmonary arteriography should be performed. If pulmonary arteriovenous malformation or pulmonary aneurysm is found, embolization treatment can also be performed. It is worth noting that after effective control of hemoptysis by interventional therapy, the cause of hemoptysis should be actively treated to reduce recurrence of hemoptysis.
