Abstract
-
PURPOSE: To analyze the cineangiographic appearance and determine the clinical importance of coronary-to-bronchial artery communication.
MATERIALS AND METHODS
The coronary cineangiograms of 4,620 patients were reviewed, and 12 cases of coronary-to-bronchial artery communications were observed in 10 patients (M:F=6:4; mean age, 48.4 years). The cineangiographic findings were analyzed and correlated with these of other imaging studies [perfusion scan (n=5), computed tomographic angiography (CTA) (n=4), conventional chest computed tomography (CT) (n=1), and conventional angiography (n=6)]. RESULT: Cineangiography revealed that hypertrophied branches of the coronary artery communicated with bronchial arteries in which adjacent hypervascular staining, was observed, and which were accompanied by pulmonary shunts (n=9). The underlying diseases identified among the ten patients were Takayasu arteritis (n=5), chronic inflammatory pulmonary disease (n=3), pulmonary thromboembolism (n=1), and or newly diagnosed pulmonary tuberculosis (n=1). The lung fields supplied by coronary-to-bronchial communication showed close correlation with the territories of perfusion defects, decreased pulmonary vascularity, or inflammatory lesions revealed by other imaging studies.
CONCLUSION
Coronary-to-bronchial artery communication can present as a secondary result of occlusive disease of the pulmonary arteries or chronic pulmonary inflammation, and in patients with hemoptysis involving, for example, incomplete embolization or myocardiac infarction, it may be problematic.
