Abstract
|
|
|
|
Normal bronchial arteries are small vessels that arise mostly from the descending thoracic aorta. Bronchial artery aneurysm is defined as a dilatation of the bronchial arteries with a diameter over 2 mm, and is reported in less than 1% of bronchial arterial angiography. A 70-year-old male patient was presented with hemoptysis. He had been treated for pulmonary tuberculosis 50 years ago. He also had a history of admission with hemoptysis 10 years ago, for which he was diagnosed as bronchiectasis on computed tomography imaging. Upon arrival to our hospital, abnormal vascular structure was detected on the mediastinum, arising from the descending thoracic aorta. It was dilated to 14 mm with a saccular form. Initially, we evaluated the structure as a bronchial arteriovenous malformation because it seemed to be drained into the pulmonary vein directly. For further evaluation, he had received a trans-catheter bronchial artery angiography. Both bronchial arteries were hypertrophied, but direct arteriovenous shunt was not detected; as such, we concluded this structure to be bronchial artery aneurysm. We performed embolization for both bronchial arteries and filled the aneurysm with coiling. He had no recurrence of hemoptysis and was discharged on 4 days post embolization. Our case reports an incidental bronchial artery aneurysm, which was initially misdiagnosed as bronchial arteriovenous anomaly, and finally treated with embolization and coiling.
