Treatment of hemoptysis by embolization of bronchial arteries. Radiology 1977; 122(1):33-7.

The most effective nonsurgical treatment for massive hemoptysis is the embolization of bronchial arteries [1-13].

Pulmonary circulation in pulmonary atresia can be supplied by a concurrent patent ductus arteriosus or bronchial arteries whereas in CAT, distinct pulmonary arteries arise from the trunk as previously described [4, 29].

Hemoptysis is common among these patients because of the severity of the bronchial wall destruction and hypertrophied bronchial arteries. In fact, hemoptysis can be a life-threatening problem with these patients because the pulmonary vessels that tend to bleed are bronchial arteries, which are systemic vessels under high pressure.

Blood may return to the LV via the pulmonary circulation as a consequence of RV ejection or directly via the bronchial arteries and Thebesian veins.

The health of the bronchial arteries is critical because they supply oxygenated blood to the lungs, as opposed to the pulmonary arteries, which carry deoxygenated blood to the lungs.

Small doses in the bronchial arteries stimulated contraction of smooth bronchial muscle and thus an increase in airway pressure.

In this system, bronchial arteries bring oxygenated blood from the left side of the heart to the airways (bronchi, bronchioles) and the supporting structures (connective tissue) of the lung.

When supportive blood nutrition is provided by bronchial arteries, the pulmonary artery obstruction caused by slow-growing cysts may remain asymptomatic.

DISCUSSION: Haemoptysis usually arises from bronchial arteries, but in case of tubercular lesions, new and collateral vessels develop from systemic circulation.

Subsequently, bronchial arteries on either side were searched using flush aortogram as a guide.
