Thoracic aneurysm expansion secondary to collateral supplies via thyrocervical trunk and intercostal arteries in a patient after thromboexclusion.
A case of thoraco-abdominal aortic aneurysm complicated after permanent clamping of the descending aorta (thromboexclusion) is reported. Angiographic and operative findings were: (1) a pseudo-aneurysm right at the distal anastomosis of previous intrathoracic bypass for pseudo-coarctation of the aorta filled by left ninth intercostal artery, which was supplied by the left internal thoracic artery; and (2) the cervical and thoracic spinal cord were supplied by the left vertebral artery and the mediastinal branch of the left thyrocervical trunk. This rare cause of a thoraco-abdominal aortic aneurysm and the significance of the subclavian artery as a source of spinal cord blood supply are discussed.
