Abstrakt EN: We assessed the proportions of smooth muscle cells, elastin and collagen in histological sections of aorta samples and studied the morphological characteristics of the elastin network in the tunica media. A new method was introduced for the assessment of structures formed by elastin membranes and fibres, using the fast Fourier transform (FFT) technique. The results of this comparative study, obtained from selected samples from 24 patients, revealed that the percentage values of the constituents of the arterial wall can not distinguish between the preserved segments of normal, atherosclerotic or aneurysmatic aorta. The results of the Fourier analysis proved that the FFT provided an efficient method for evaluating cross sections of the elastin membranes and fibres, reflecting their anisotropy. We discuss the methodological difficulties and biomechanical implications of our work as well compare it to other methods of elastin analysis.
