Abstract
The purpose of this paper is to study whether there is a trend toward histologic type specific structure of the vessels in lung cancer tissue or not by means of selective bronchial angiography.(B. A. G.) Special attention was paid to study the detailed structure of bronchial arterial nets with the aid of macroangiography and microangiography in the resected lung combined with B. A. G., because angiographic findings of the resected lung were very usefull for analisis of B. A. G.
122 cases of lung cancer, practiced with B. A. G. and 79 cases out of them were studied with macroangiogram and microangiogram.
Close relation between histologic type of the tumor tissue and the angiographic structure of tumor vessels, which was demonstrated in B. A. G.(Table 3) and angiogram of the resected lung, especially the fine structure of the vascular nets, was observed.
Most of histologic type of lung cancer were determined by reading carefully the various angiographic patterns which depend upon the characters of cancer tissue, such as, mode of bronchial and lung parenchimal invasion, site of origin, existence of necrosis or scar and so on. To decide the histologic type, the most important facters which appeared in angiogram were the characters of stroma of cancer tissue and behaviour of cancer to the bronchus wall.
