[Clinical investigation of the branching formation of the bronchial arteries in the Japanese].
It is imperative to be familiar with anatomical variation in the branching formation of the bronchial artery for radiologists attempting an interventional angiography to the pulmonary diseases such as hemoptysis or pulmonary carcinoma. The anatomy of the bronchial arteries reported by Cauldwell et al. is the most frequently quoted literature in the world as well as in Japan. However, we had noticed that some discrepancies exist between our clinical experience and those in Cauldwell's report regarding anatomical variation of the bronchial arteries. Then, we reviewed the bronchial arteriograms in 640 patients. We included 412 patients in investigation, in which it was possible to identify the branches supplying all pulmonary lobes. In 50 out of 640 patients, catheterization of the branches supplying the lesion was failed. Branching formation of the bronchial arteries is extremely variable and complicated by presence of the accessory bronchial arteries and anastomosing branches from the systemic arteries, which may be enlarged in various pathological conditions. Our results showed that the most common branching type was single artery on each side (50.0%), followed by common trunk (14.1%). The incidence of single on the right and dual on the left, most common in Cauldwell's series, was only 12.9%. Kasai and Chiba also pointed out these differences in their detail report investigating 100 cadavers. These discrepancies between the data may be due to differences of methodology or due to differences between the races. The authors feel that Cauldwell's data should not be referred to the anatomical variation of the bronchial artery in Japanese.
