[Surgical Repair of Stanford Type A Acute Aortic Dissection Associated with Anomalous Retroaortic Left Brachiocephalic Vein;Report of a Case].

Anomalous retroaortic left brachiocephalic vein( ARLBV) is a rare vascular abnormaly, usually asossiated with congenital heart diseases. We present a very rare case of Stanford type A acute aortic dissection associated with ARLBV. A 70-year-old man was referred to our hospital complaining of worsening back pain and chest pain. Computed tomographic angiogram showed Stanford type A acute aortic dissection from the ascending aorta to the distal abdominal aorta. Furthermore, systemic venous anomalies were revealed. The left brachiocephalic vein coursed the left side of the aortic arch, anterior to the central pulmonary artery, and posterior to the ascending aorta, and joined the right brachiocephalic vein. Replacement of the ascending aorta was performed in an emergency, and the postoperative course was uneventful.
