abstractsThe coronary artery as a responsible vessel for hemoptysis is very rare. This patient was admitted to the hospital with bronchiectasis and hemoptysis, and the right coronary artery was found to be one of the non-bronchial systemic arteries by computed tomography angiography, and the hemoptysis stopped immediately after successful embolization of all bronchial arteries and non-bronchial systemic arteries by bronchial artery embolization. However, the patient had a recurrence of a small amount of hemoptysis 1 month and 3 months after surgery. The patient underwent lobectomy of the lesion after multidisciplinary discussion and did not have any hemoptysis after surgery.
