Abstract
Background. Racemose hemangioma of the bronchial artery is an extremely rare disease that is characterized by congenital bronchial artery malformation. In this report, we describe a case of racemose hemangioma of the bronchial artery that was treated by selective coil embolization of the bronchial arteries. Case. The patient was a 30-year-old man who did not have any specific complaint. An abnormal shadow in the right lung field was detected on a regular health checkup chest X-ray film. The chest computed tomography (CT) scan showed an abnormal blood vessel around the right lower lobe bronchus. Racemose hemangioma or bronchial artery-venous fistula were suspected in the patient and he was referred to our department. Enhanced chest CT scan performed after hospitalization showed two origins of the bronchial arteries from the descending aorta. In addition, dilatation and convolution of these arteries were also observed. Bronchial artery angiography revealed aneurysms arising from two of the bronchial arteries, which were racemose, and there was a shunt to the pulmonary artery. We considered this case suitable for bronchial artery embolization and obtained complete occlusion using 7 detachable coils and 5 microcoils. Result. The embolization procedure was successful without any recurrence at 25 months after treatment. Conclusion. Based on a previous study, we concluded that selective coil embolization of bronchial arteries is an effective method of treatment for racemose hemangioma of the bronchial artery. Selective coil embolization of the bronchial arteries is an effective method of treatment of racemose hemangioma of the bronchial artery.
