Endovascular Repair of an Intrathoracic Subclavian Artery Aneurysm in a Patient With Dextrocardia.

This manuscript describes an endovascular repair of a symptomatic, large proximal left subclavian artery aneurysm in a patient with dextrocardia and right-sided aortic arch and absent bilateral internal carotid arteries. The patient had surgical reconstruction as an infant for congenital heart disease with Ventricular Septal Defect, bifid sternum . Given her previous surgical history, we declined an open operation and performed an endovascular repair with stent grafts to successfully repair the subclavian artery aneurysm. The patient had an uneventful postoperative course and follow-up ultrasonography demonstrated successful repair with preservation of flow through the left subclavian and vertebral arteries with resolution of her symptoms.
