[Morphological consideration of the bronchial arteries and its interventional angiography].

The authors dissected the bronchial arteries macroscopically in 40 human adults. (1) Two right and two left bronchial arteries were most commonly observed in 19 cases (48%). (2) Besides the intercostobronchial artery, one more right bronchial artery was mainly distributed to the lower lobe of the right lung. (3) Relationship between the intrapulmonary distribution of each bronchial artery and the lobe of the lung was not definite. Technological considerations of the BAG were presented from the results of this study.
