    Abstract:
    In seven patients with nonmalignant disease, we bronchoscopically observed various types of bronchial arterial lesions that may have caused hemorrhage. Five of the seven showed a bulging lesion, and the other two demonstrated an intrabronchial mass. We also examined these seven patients using selective bronchial arteriography. Herein we report our comparative study of the bronchoscopic findings and the bronchial arteriograms of these bronchial arterial lesions. The bulge observed in bronchoscopy corresponded either to an aneurysm or to a hypervascular area in the bronchial arteriogram. The mass lesions corresponded to a hypervascular area or a focal dilatation in the bronchial arteriogram. The intrabronchial lesions observed bronchoscopically either disappeared or were significantly diminished by bronchial arterial embolization for management of the hemorrhage. A histologic examination in two patients who underwent surgery revealed vascular lesions corresponding to the intrabronchial lesions in bronchoscopy. The results of this comparative study have important application in the bronchoscopic examination of bronchial arterial lesions in patients with hemoptysis.
