[Intimal lipoidosis of the coronary arteries of newborn infants and infants in the 1st year of life].

Post-mortem morphological examination of the coronary arteries in 76 newborns and children of the first year of life was performed. Cases of the cardio-vascular pathology were not included into the study. Intimal thickening, either diffuse or focal, was revealed in 58 cases. The degree and frequency of the diffuse thickening of the intima (DTI) were higher in boys. DTI was present predominantly in the anterior interventricular artery and much less frequently in the circumflexal coronary artery. Intimal lipoidosis was found un 21 cases, with the same incidence in both boys and girls, but somewhat more frequently in the right coronary artery. Topography of both intimal lipoidosis and DTI was similar. The traces of cholesterol, its esters and predominantly neutral fat were defected histochemically in the foci of intimal lipoidosis.
