Pulmonary artery in the region supplied by daughter branches

The branching pattern of the pulmonary artery was examined in the autopsied right lung of a 76-year-male, (inflated and fixed lung), in the regions supplied by daughter branches. Ordinarily, the pulmonary arteries are accompanied by the bronchi, but not necessarily by the daughter bronchi. There were two types of branching patterns of the pulmonary artery in the regions be occupied by daughter branches. In one, the pulmonary artery was not accompanied by the daughter bronchi at the beginning of the branch, but was accompanied by the daughter branch in peripheral regions. In the other, some branches of pulmonary artery distributed to the hilar region from neighbouring daughter branch areas. It is very important to consider daughter branches of the pulmonary artery as well as the inherent structure of the lung

A case of adenocarcinoma showing atelectasis which changed little in size over a long period of time

An abnormal shadow was noted on a chest radiogram of a 61-year-old woman three years ago. This abnormal shadow has changed little over the three years. Examinations changed this year, including chest tomogram, CT and bronchofiberscopy, showed atelectasis of the right S(3) without obstruction of B(3)(a) and B(3)(b). Histologically, a well differentiated adenocarcinoma was found in a transverse bronchial lung biopsy specimen. Postoperative staging was confirmed to be pT(2) NoMo
