Morphological study of the Korean bronchial arteries

(Directed by Prof. Kum Kuck Choi,M.D.)

The bronchial arteries, which provide the nutrient supply to the lungs, have been

studied in the normal gross anatomy and the pathology as well. The present study

was made to observe the normal gross anatomy of the Korean bronchial arteries and

to compare with the results obtained by other investigators in other nations.

114 Korean cadavers of both sexes consisting of 52 males and 62 females, which

were arranged for dissection of the gross anatomy at Yonser University, College of

Medicine, were used. The author has selected the specimens carefully to eliminate

any unsuitable dissections performed for this study.

In the types of both bronchial arteries by number, the Type 2, which was at least

one bronchial artery to each lung, was observed in 57 out of 114 cases(about 49.99%

in the incidence). The Type 2 showed the most frequent incidence in this category.

A right bronchial artery frequently arised in common with an aortic posterior

intercostal artery. One right bronchial artery arised in common with an aortic

posterior intercostal artery was found in 61 out of 114 cases(about 53,5% in the

incidence). The occurrence of one right bronchial artery arised from the first

aortic posterior intercostal artery was 50 out or 61 cases(about 81.96% in the

incidence).

In the mode of origins of bronchial arteries in each body, all bronchial arteries

arised independently of each other from the aorta and its branches, were found in

66 of 114 cases(about 57.86% in the incidence). In the remaining cases or 48 cases,

2 or more bronchial arteries arised from common stems which were tabulated in the

Table 3.

In the left sides of 114 cases 155 bronchial arteries were found by the author,

Among them 139 bronchial arteries arised from the thoracic aorta(about 89.68% in

the incidence) and 12 bronchial arteries arised from the aortic arch (about 7.74%

in the incidence).

In the right sides of 114 cases 150 bronchial arteries was observed. 79 out of

150 bronchial arteries arised from the thoracic aorta(about 52.65% in the

incidence) and 9 bronchial arteries arised from the aortic arch(about 6% in the

incidence). From the first aortic posterior intercostal arteries of the right side

52 bronchial arteries arised(about 34.67%), which were differed from those of the

left in respect to sites of origin from the aorta.

Consequently the author has made to compared the Korean results with those

results obtained by others in other nations and realized that in some categories

concerning the normal gross anatomy of the bronchial artery the results were not

similar each other.
