How is bronchial artery embolization done?

Is bronchial artery embolization safe?

Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis.

What is Rasmussen aneurysm?

What are bronchial arteries?

The bronchial arteries carry oxygenated blood to the lungs at a pressure six times that of the pulmonary arteries. The bronchial arteries provide nourishment to the supporting structures of the lungs, including the pulmonary arteries, but generally do not participate in gas exchange (1,2).

What is pseudo aneurysm?

A pseudoaneurysm, or pseudoaneurysm of the vessels, occurs when a blood vessel wall is injured and the leaking blood collects in the surrounding tissue. It is sometimes called a false aneurysm. In a true aneurysm, the artery or vessel weakens and bulges, sometimes forming a blood-filled sac.
