[The problem of dissecting aneurysm of the aorta and its benign course].

On the basis of a personal case, the clinical, diagnostic and therapeutic problems of variants of dissecting aneurysm of the aorta with benign course are discussed. The usefulness of cardio-aortic angioscintigraphy in the interests of early diagnosis of aneurysm and aortography by catheterism for specifying its location and extent, is pointed out. Spontaneous benign development would seem to be tied up with the affected area of the aorta, the modalities of dissection, and above all with the establishment of a distal return breach for blood flow into the aortic lumen. The predominant role of cystic medionecrosis in determining dissection is stressed and the usefulness of intensive pharmacological therapy based essentially on hypotensive and beta-blocking substances confirmed.
