[INSTRUMENTAL CRITERIA OF DIFFERENTIAL DIAGNOSIS OF THE ASCENDING AORTA ANEURISM IN PATIENTS OF DIFFERENT AGE]

Criteria of differential diagnosis for the aortal aneurysm etiological factor, especially in patients of a young age, are studied insufficiently. Peculiarities of cardio—vascular remodeling in patients of different age, in whom the ascending aorta aneurysm was diagnosed, were studied with the objective to search for criteria of differential diagnosis of the aneurysm etiological factor. Echocardiography constitute the main method of the ascending aorta aneurysm diagnosis. There was established, that changes in the cardio—vascular remodeling indices in patients are caused not by cardiac pathology only, but by their age as well. The aortal bulb dilation is frequently caused by dysplasia of connective tissue and dilation of the ascending aorta distal part — predominantly by atherosclerosis and arterial hypertension. Enhancement of the ascending aorta/aortal bulb coefficient (aortal bulb diameter/ascending aorta diameter) more, than 1.11 have had witnessed, as a rule, the connective tissue origin of the ascending aorta aneurysm; the coefficient lowering down from 0.88 — about atherosclerotic and/or hypertensive genesis of aneurysm
