title: Coronary CT findings of coronary to bronchial arterial communication in chronic pulmonary disease.
abstract: To describe the coronary CT findings of coronary-to-bronchial artery communication (CBAC) in chronic pulmonary disease. Coronary CT was performed in 15 patients with chronic pulmonary disease using 64-channel or greater multidetector CT. Among those patients, one or two CBACs were identified. A retrospective analysis of the CT findings was done to determine the originating artery, arterial course of the communications and other associated results. The main underlying pulmonary disease was bronchiectasis (n = 12). The origin of the CBAC was from the left atrial (n = 7) or sinoatrial (SA) nodal (n = 3) branch of the left circumflex artery in nine patients and the SA nodal branch of the right coronary artery in six patients. The CBAC was connected to the left bronchial artery in 11 patients and the right bronchial artery in five patients. The course of the CBAC passed through the interpulmonary venous bare area between reflections of the serous pericardium of the transverse and oblique sinuses in 13 patients. In three patients, it passed through the perivascular space around the left upper or lower pulmonary vein. In one patient, there were two communications-one through the interpulmonary venous bare area and the other through the perivascular space around the left lower pulmonary vein. There was no significant coronary arterial stenosis except in two patients. Bronchial arterial hypertrophy was found in all 15 patients. Detailed analysis of coronary CT can be a helpful guide for hemodynamic significance and clinical management including embolotherapy for CBAC in patients of chronic pulmonary disease with hemoptysis.
