[Thoracic aortic aneurysm associated with pseudocoarctation; report of a case]

Abstract

A 20-year-old woman without any significant history of disease was referred for further investigation of an aortic arch aneurysm. The arterial blood pressure in the right arm was higher than in the left arm and in both legs. An multi-detector row computed tomography (MDCT) and an aortogram revealed narrowing of the middle aortic arch, kinking at the ligamentum arteriosum, subsequent multiple aneurysmal formation, and stenosis and narrowing of the descending aorta. The left subclavian artery branched from the 1st aneurysm. We resected the aneurysms and reconstructed the distal aortic arch and left subclavian artery using a woven polyester graft. This case was diagnosed as thoracic aortic aneurysm associated with pseudocoarctation, which is a quite rare congenital anomaly.
