Bronchial Artery Embolization (BAE) is a highly effective procedure used to stop severe bleeding in the lungs.
Common Indications for Bronchial Artery Embolization
Your doctor will urgently request this procedure if you are:
- Coughing up dangerously large or continuous amounts of blood (a condition called hemoptysis).
- Experiencing lung bleeding due to chronic conditions like tuberculosis, cystic fibrosis, or severe bronchiectasis.
What exactly does a BAE do?
When lung tissue is inflamed or diseased, the bronchial arteries can grow abnormally large and fragile, making them prone to bursting. BAE blocks these abnormal vessels to stop the bleeding. Importantly, blocking these specific arteries is completely safe because the lungs get their primary oxygen supply from a completely different set of blood vessels (the pulmonary arteries).
What happens during the procedure?
A catheter is placed into an artery in your groin and navigated up into your chest using X-ray guidance. X-ray dye is injected to map out the abnormal, bleeding arteries. Once located, tiny particles are injected through the tube to block the fragile vessels and stop the bleeding.
Do I need to prepare?
If it is a scheduled procedure, you will fast beforehand. In emergency situations, the procedure is done immediately to protect your airway.
How long does it take?
The procedure typically lasts between 1 and 3 hours.
Will it be painful?
The procedure is done using local numbing medicine and sedation. You will not feel the tube in your chest. Some patients may experience a brief feeling of chest tightness or difficulty swallowing immediately after the procedure, as well as fatigue or flu-like symptoms for a few days, which is a normal reaction to the embolization.
Conclusion
Bronchial Artery Embolization is a life-saving, minimally invasive procedure. By accurately targeting and sealing the bleeding vessels in the lungs, it provides immediate relief from coughing up blood and helps patients breathe safely again.
