  • Title: [Rupture of the aortic arch due to bacterial aortitis--a case report of a patient undergoing successful surgical therapy].
    Author: Sudo Y, Takahara Y.
    Journal: Nihon Kyobu Geka Gakkai Zasshi; 1996 Dec; 44(12):2221-4. PubMed ID: 8990901.
    Abstract:
    A 59-year-old man came to our hospital because of hoarseness and chest pain. On initial examination, a chest roentgenogram showed no abnormality. Three weeks later, while the patient was waiting to undergo a computed tomographic (CT) scan, shock suddenly developed. A chest roentgenogram revealed an extremely wide mediastinal shadow. A CT scan revealed rupture of the aortic arch near the base of the left subclavian artery, although there was no aneurysm. An emergency operation was performed. The ruptured aortic arch was replaced with an artificial graft during cardiopulmonary bypass with selective cerebral perfusion. A diagnosis of infectious aortitis was not made until a pathologist discovered colonies of gram-positive cocci in the resected specimen of the aortic arch. Postoperatively, antibiotics were administered for only four days. The patient is well about two years after the operation. Infectious aortitis had a very low prevalence and rarely involves the thoracic aorta. However, we should be aware of that it may cause aortic rupture even in the absence of aneurysmal dilatation.
