A Method for Arteriography of the Bronchial Artery

Abstract

(1) A new radiologicol method of arteriography for visualization of the bronchial artery applying the occlusion of the descending thoracic aorta is described.
(2) In order to investigate the safety limit of the occlusion of the descending aorta, 9 dogs were clamped of their aorta at the level lower than that of the left subclavian artery and relationship between occluded duration and the complications thereby occurred was followed up. As a result of this experiment, the safety time limit of occlusion is within 20 minutes.
(3) The changes of the hemodynamics, especially that of the proximal aortic pressure in the course of occlusion in the dogs and human beings were studied.
(4) For the purpose of preventing anticipated accidents certain contraindications were set up.
(5) The images of the bronchial arteries in normal dogs and those in cases with the bronchiectasis and pulmonary tuberculosis were demonstrated.
