Is bronchial artery embolization safe?
Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis. However, nonbronchial systemic arteries can be a significant source of massive hemoptysis and a cause of recurrence after successful BAE.
What is the most severe complication of bronchial artery embolization?
Of these complications, transient chest pain is the most common, with a reported prevalence of up to 89%. The most feared complication of BAE is spinal cord ischemia due to the inadvertent embolization of a spinal artery, fortunately occurring in <5% of cases in most studies.
What is bronchial artery?
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 supplies the bronchial artery?
Although there is much variation, there are usually two bronchial arteries that run to the left lung, and one to the right lung and are a vital part of the respiratory system….

How long does bronchial artery embolization take?
Often, several blood vessels have to be embolized for the best treatment of your condition. The procedure may take anywhere between 2 and 4 hours to perform.
How long does an embolization last?
Most women get significant symptom relief in the first three months after treatment. In addition, some research shows that five years after treatment uterine artery embolization continues to reduce symptoms such as heavy bleeding, urinary incontinence and abdominal enlargement in most women.
What does severe BAE mean?
Brief Summary: Severe hemoptysis is a life-threatening condition, with an unpredictable course. The efficacy of bronchial artery embolization (BAE) is well established for the treatment of severe hemoptysis, with short and long-term bleeding controls obtained in 70 to 100% and 50 to 90% of cases, respectively.
What is the treatment of hemoptysis?
Endovascular embolization is the safest and most effective method of managing bleeding in massive or recurrent hemoptysis. Embolization is indicated in all patients with life-threatening or recurrent hemoptysis in whom MDCT angiography shows artery disease.
Where do bronchial arteries drain?
The bronchial veins from the larger airways and hilar region drain through the systemic veins (particularly the azygos system) into the right atrium. However, bronchial flow to the intrapulmonary structures connects to the pulmonary circulation and drains through the pulmonary veins into the left atrium.
What is the origin of right bronchial artery?
The right bronchial artery has a common origin with a posterior intercostal artery called the intercostobronchial trunk (ICBT) and arises from the right anteromedial aspect of the thoracic aorta 8.
What is BAE surgery?
A bronchial-artery embolisation (BAE) is a procedure where X-rays are used to examine the bronchial arteries (arteries in your lung). This allows the doctor to find the bronchial artery which is bleeding and causing your haemoptysis (coughing up of blood).
Can embolization go wrong?
There is always a chance that an embolic agent can lodge in the wrong place and deprive normal tissue of its oxygen supply. There is a risk of infection after embolization, even if an antibiotic has been given.
Is the bronchial artery on the thoracic aortography?
When normal, the bronchial arteries are not typically well visualized on thoracic aortography.
What are the normal findings of the bronchial arteries?
CECT findings of normal bronchial arteries ( a, arrow), with a reduced caliber inferior to 1,5 mm. The remaining images show a patient with hypertrophy of the bronchial arteries, with a caliber exceeding 2 mm ( b, c, d; arrows).
How big is the bronchial artery in feet?
There are most commonly 3 main bronchial arteries, one right and two left. In addition, there are often additional smaller bronchial arteries arising from the descending thoracic aorta 7. They are small caliber arteries, with a diameter of 1.5 mm at the origin, tapering down to approximately 0.5 mm at the pulmonary hila level 6.
Where does CECT imaging of the bronchial arteries take place?
In the evaluation of the bronchial arteries, CECT imaging should be acquired from the supraclavicular regions to the level of the renal arteries, depicting both orthotopic and ectopic bronchial arteries and possible collateral branches to the pulmonary arterial system.
