Abstract
Morphological diagnosis of lesions in the peripheral respiratory tract was performed using two selective alveolo-bronchographies with and without magnification radiography.
In order to perform selective alveolo-bronchography (SAB), a red KIFA angiographic catheter, with a 6.6F outside diameter, was inserted from the infusing contract medium channel and prewedged into the site where the contract medium was injected, through which 2-3ml of contract medium was gradually injected under X-ray TV visualization. The patient was placed in a supine position for SAB and 3-4 times magnification was used. Simultaneously, a digestive-tract X-ray apparatus was used for SAB.
Subjects consented of 51 patients in whom lesions were limted to the peripheral respiratory tract. The patients were divided into the following 4 groups according to the results of selective alveolo-bronchography: The group in which the terminal bronchioles were narrowed (I), the group in which the terminal bronchioles were dilated (II), the group in which the alveoles ducts were dilated (III), and the group in which abnormality in the alveoli was observed (IV).
