Congenital arteriovenous malformation of the thoracic aorta treated with thoracic endovascular aortic repair (TEVAR)

A 44-year-old female was referred to our clinic for a 20-year history of an enlarging upper back mass. After further evaluation with computed tomography angiography, we diagnosed her with a thoracic aorta arteriovenous malformation. This malformation originated from the aorta and drained into her intercostal veins. A thoracic endovascular aortic repair was done to cover all but one of the feeding arteries. The case was uneventful, and the patient was discharged on postoperative day 1. An aortic arteriovenous malformation is extremely rare; thoracic endovascular aortic repair was helpful in this case to prevent further enlargement of this anomaly.
