[Stereoangiography of the bronchial arteries: technic and indications]

Stereo-angiography of the bronchial arteries has been performed in 11 patients with bronchial carcinomas. An attempt has been made to establish the spatial relationship between their main stems and the proximal bronchial system. Important details were transferred from each half of the stereo pairs into transparent sheets; this improved stereoscopy and made it easier to appreciate the relationship to the tracheal bifurcation. Characteristic relationships between various types of bronchial arteries and the tracheo-bronchial system could be recognised. Improvements can be expected from the use of a stereo-DSA technique. Stereo-bronchial arteriography is useful for demonstrating pre-operatively their exact position in order to prevent unnecessary ligation and for improving localisation of bleeding points which can only be reached surgically.
