Aneurysms of an aberrant subclavian artery are rare. They are usually secondary to atherosclerosis. Dysphagia is the most common presenting symptom. The diagnosis of these lesions is most easily established by CT scan. Biplane arteriography is necessary in order to clearly analyze the aortic arch and its branches. Surgical resection is usually indicated. Numerous procedures have been proposed to treat these lesions and controversy exists concerning the best surgical technique. We treated a patient who suffered from an aneurysm of an aberrant subclavian artery. The surgical technique is detailed as well as a review of all the cases of the literature.
