Giant dissecting aortic aneurysm with concealed perforation in an 81-year-old female.

This paper describes the history of an 81-year-old female suffering from a giant dissecting aortic aneurysm with concealed perforation within the thorax. The patient had suffered from arterial hypertension for about 10 years and had been treated with thiazide. Nine months prior to admission the patient was in a state of collapse, and ultrasound examination revealed an intra-abdominal aortic aneurysm. At this time thoracic x-ray showed aortic sclerosis and elongation of the aorta but no signs of aneurysm formation. After this episode the patient was symptom-free for the next 9 months. Following a further syncopal attack with severe thoracic pain, the patient was hospitalized at the intensive care unit. Both in thoracic x-ray and computed tomography of the thorax, a pronounced dissecting aortic aneurysm with perforation of the thoracic aorta into the mediastinum could be established. Because of the patient's poor general condition and advanced age, as well as far-reaching pathological findings, surgery was not advised by either the heart and vascular surgeon or the anesthetist. Following 1 week's intensive therapy, the patient's general condition improved greatly, with stabilization of thoracic pain, blood pressure, and respiratory action. On the other hand, thoracic x-ray, computed tomography, and magnetic resonance imaging produced a distinct progression of the aneurysm with consequent mild displacement of mediastinum and left lung. Laboratory examinations for syphilis showed no evidence of that disease. After further improvement the patient was discharged 4 weeks after admission and has been symptom-free for 6 months in spite of the extensive pathological findings described herein.(ABSTRACT TRUNCATED AT 250 WORDS)
