104 selective bronchial arteriographies were performed in 25 patients with bronchopulmonary neoplasia, 11 with mediastinal tumours, 15 with bronchopulmonary inflammation, and 53 with haemoptysis. An assessment is made of the diagnostic value of the information obtained. It is felt that this form of examination is particularly useful in detecting the site of bleeding cases of haemoptysis, and in the provision of treatment by means of embolisation.
The significance of blocked arteries with regard to minor hemorrhagic infarctions in the lung in venous and systemic fat embolism is discussed. In an experiment it is proved that blood in the anastomoses between the arteria bronchialis and arteria pulmonalis (blocked arteries) contains fat emboli. It is suggested that these fat emboli may in addition be transported into an area of the lung, which is no longer functional following embolic occlusion of a branch of the arteria pulmonalis.
RI-angiography with 99mTcO4- was carried out using a scintillation camera with a digital minicomputer for the purpose of imaging of bronchial blood flow in various lung diseases, and as application of dual radioisotope techniques, other imagings such as tumor imaging with 197HgCl2 or 67Ga-citrate and/or perfusion imaging with 99mTc-MAA, were performed simultaneously in patients remaining the same position, too. The image as a iso-count map extracted out of the image of 197HgCl2, 67Ga-citrate or 99mTc-MAA, was superimposed to the brightness image of RI-anigogram (aortic phase). By these procedures, the image of bronchial blood flow were obtained in some patients with lung cancer, pulmonary tuberculosis, lung abscess, and chronic bronchitis. The dual radioisotope techniques using RI-angiography and the other imaging were useful to make isotope diagnosis of lung diseases more reliable, and the image superimposition methods using RI-angiogram and the image of tumor or perfusion, were useful to improve anatomic orientation of the former.
