title: [Pseudocoarctation associated with dissecting aneurysm of the aorta: a case report].
abstract: A case of pseudocoarctation with dissecting aneurysm of the ascending aorta and arch is reported. A 49-year-old man was admitted with chest pain and loss of consciousness. Angiogram showed kinking of the aortic isthmus and dissecting aneurysm of the ascending aorta. There was no pressure gradient between arms and legs. Prosthetic graft replacement of the ascending aorta was successfully performed by the use of total cardiopulmonary bypass with moderate hypothermia. Etiology of the development of pseudocoarctation is unknown, however, hypothesis that embryological abnormality of the aortic arch is one of the contributing factors has been widely accepted. This case was accompanied by bicuspid aortic valve. It is suggested that the developmental etiology of this case seems to be similar to that of classical coarctation of the aorta. Development of the dissecting aneurysm is supposed to be due to hypertension of the upper body during exercise, even though there is no pressure gradient at rest.
