After a lobectomy the appearance of the chest roentgenogram may return so nearly to normal that it is frequently very difficult to tell which lobe has been removed without refering to the thoracic surgeon's record. The review of literature failed to disclose previous articles concerning the differential diagnosis between upper and lower lobectomy. Clues of a lobectomy may be found in the rib cage, hilar shadows, pleura and diaphragms, but they do not specifically indicate which lobe has been removed. In the present study we analysed anatomico-spatial changes of the pulmonary basal arteries, hilar point, vascular redistribution, diaphragm and rib cage on the plain chest films taken before and after a lobectomy in 33 cases seen at the Department of Radiology. St. Mary's Hospital, Catholic Medical College. Firstly we observed the pulmonary basal artery after a lobectomy on plain chest film. In 12 cases of upper lobectomy the pulmonary basal artery was easily indentified in every cases. However in all of 21 cases of lower lobectomy, the pulmonary basal artery was not identified. Next, a shift of the hilar point was checked after a lobectomy. Regarding to vascular redistribution, the blood vessels was counted at upper and lower lung fields by Simon's method before and after a lobectomy, respectively. Finally, the level of the diaphragm was compared in the pre. and post-operative films and resected rib was scrutinzed. The present study revealed that the most reliable sign to indicate specifically which lobe has been resected is persistence or disappearance of the pulmonary basal artery. Then, i.e. in upper lobectomy the pulmonary basal artery was easily identified, but in lower lobectomy the pulmonary basal artery was not dectable. Other findings such as vascular redistribution, elevated disphragm and resected rib were not specific.
