Description

The bronchial arteries are the main sources of high-pressure oxygenated blood and nutrients to the lungs in supporting components, which are including in the pulmonary arteries and they only provide for 1% of overall lung blood flow. They are an important element of the respiratory system. Distal microvascular anastomoses connect the bronchial arteries to the pulmonary arterial system. Bronchial arteries are highly flexible, with the ability to increase flow from 1% to 30% of cardiac output in response to a pulmonary injury. The bronchial arteries transport to the bronchial tree, major blood vessels, lymph nodes, oesophagus, and pleura, and have a considerably narrower diameter than the pulmonary arteries. Some diseases may lead to an impairment of the pulmonary circulation.

There are normally two bronchial arteries that flow to the left lung and one to the right lung and that arise directly from the anteromedial thoracic aorta. The right bronchial artery shares an origin with the intercostobronchial trunk, a posterior intercostal artery, and emerges from the right anteromedial part of the thoracic aorta or the upper left bronchial artery. The left bronchial arteries are generally second. In descending thoracic aorta is inferior to the origin of the third posterior intercostal artery. It is also divided into two left bronchial arteries are such as Superior left bronchial artery is starts from the aorta around the aortic arch’s level, lateral to the carina, and posterior to the left major bronchus. Inferior left bronchial artery is arises from the aorta parallel to the superior artery, but inferior to the left main bronchus.

Embolization is a very successful and less intrusive alternative to open surgery for controlling bleeding. It can be used to cure injuries, manage or prevent aberrant bleeding, cut off blood vessels supplying a tumour, remove abnormal connections between arteries and veins, or close off vessels giving blood to a tumour.

Bronchial Artery Embolization (BAE) is a safe and effective for controlling bleeding in life-threatening hemoptysis and also process in which the bronchial arteries are examined using X-rays. The long-term results of bronchial artery embolization for the treatment of non-massive hemoptysis in patients with a range of underlying diseases of hemodynamics and coagulopathy had a lower clinical success rate. To identify prognostic variables related with recurrent bleeding. Who may have prolonged nonrecurrence intervals following BAE, have had a favourable clinical result. Recurrent bleeding was linked to tuberculosis sequelae and the existence of abnormal bronchial arteries or non-bronchial systemic collaterals. The use of embolic materials greatly reduced the risk of recurrent bleeding. Conservative treatment alone may not provide superior long-term management of recurrent hemoptysis and quality of life than the operation. This helps the doctor to locate the bleeding bronchial artery that is causing your haemoptysis. While BAE may be a feasible alternative for treating severe, refractory hemoptysis in the short term, it is not a long-term cure and comes with considerable risks. In 90% of patients with major hemoptysis, the bronchial artery system is the primary cause of bleeding, followed by the pulmonary arteries and nonbronchial systemic arteries.
