Aneurysms of the intrathoracic subclavian artery are extremely rare. A 74 year-old man was referred to our hospital with an abnormal chest X-ray film. Contrast computed tomography revealed an intrathoracic left subclavian artery aneurysm. Via left 4th posterolateral thoracotomy, the aneurysm was exposed under systemic deep hypothermia and circulatory arrest. The distal arch was replaced with a 26 mm single-branched graft and the left subclavian artery was reconstructed with a 10 mm graft.

Coarctation of the thoracic aorta is not often diagnosed after childhood. The combination of subclavian artery aneurysm in association with coarctation of the aorta is even less frequent. A review of the literature elicited only seven previously reported cases of such an association. Presented herein is a case of a young adult with coarctation of the aorta and secondary left subclavian artery aneurysm, diagnosed incidentally. We discuss the incidence of these rare conditions and possible causes for their co-existence.

Two infants with coarctation of the aorta were successfully repaired by the modified method of subclavian flap aortoplasty with preservation of arterial blood flow to the left arm. The left subclavian artery was detached from the aorta at its origin, opened longitudinally in its posterior wall and sutured over the coarctation site. Widening of the stenosis and preserving of the blood flow to the left arm were obtained. This operative technique seems advantageous without complications induced by sacrificing the continuity of the subclavian artery, reserving the advantages of the former subclavian flap aortoplasty.

Two patients with neurofibromatosis presented with expanding masses at the left supraclavicular region. Computed tomography (CT) scans revealed vascular masses. The patients underwent surgery and ruptures of the left subclavian artery were found. Both patients were treated by ligation of subclavian artery.

In recent years, pediatric cardiologists have decreased their reliance on cardiac catheterization for diagnosing selected cardiovascular anomalies. A large part of this shift away from the more invasive diagnostic techniques has been due to improvements …
