The anatomical variants of the bronchial arteries have been reported in cadaveric studies, angiography, and computed tomography angiography (CTA); the latter was considered the most suitable method [14,15,18-21].
The objective of our study was to analyze the arterial origin, branching pattern, location ostium, vertebral level of origin, mediastinal trajectory, and diameter of the bronchial arteries using CTA.
"When the bronchial arteries
are sacrificed and not restored when lungs are transplanted, that leaves the airways dependent on collateral flow from the pulmonary artery system," Dr.
Conducting airways receive their blood supply from branches of bronchial arteries
, while the terminal respiratory units receive blood from branches of the pulmonary arteries.
Additional bronchial arteries
were missed in the initial angiogram and detected on a subsequent study in three patients.
[sup], The first procedure for embolization therapy is a complete angiography of the pulmonary vascular tree when bleeding bronchial arteries
are seen, embolization therapy is carried out.
About 10% of ALCAPA patients can survive to adulthood by well-developed intercoronary and extra coronary systemic collaterals (mainly from the bronchial arteries
) (2, 4).
In cases where bronchoscopy fails to identify the cause, angiography of the bronchial arteries
can be diagnostically helpful, since the bronchial arteries
are frequently the cause of massive haemoptysis (90%) (8,9).
(4) The aneurysms usually involve the pulmonary and/or the bronchial arteries
, although the systemic circulation can be affected too.
A bronchial artery angiogram showed hypertrophied bronchial arteries
in the right upper lobe with no bleeders & on the left side it was normal.
These branches persist as enlarged supradiaphragmatic and infradiaphragmatic aortic branches, or as bronchial arteries
in cases in which the pulmonary artery does not develop (2).
The source of hemoptysis in cavitary pulmonary tuberculosis is usually from the bronchial arteries
. Although pseudoaneurysm of bronchial arteries
is an important source of hemoptysis, it is seen infrequently.
