Abstract
A 44-year-old woman in whom multiple descending aortic aneurysms with pseudocoarctation was diagnosed underwent graft replacement. The aneurysms consisted of two large and one small aneurysms. One of the large aneurysms was a fusiform type aneurysm (38mm in diameter), and another one was a saccular type aneurysm (53mm in diameter). There was a small saccular type aneurysm (12mm in diameter) the site of the at stenotic lesion, and the wall of the small aneurysm was very thin. Atherosclerotic changes were not found inside the aneurysmal wall. Aneurysm occurring at the proximal side of the stenotic lesions of pseudocoarctation are rare, and only four cases have been reported in Japan.
