title: [Cardiac vessels of human fetuses and newborn infants].
abstract: The anatomy of the cardiac arteries has been studied in 78 and that of the veins--in 74 total preparations of human fetal hearts 3--10-lunar month-old and in newborns. The cardiac vessels are injected with contrast masses, erythrocytes are stained with benzidine, histotopograms are made. In the fetuses all branches of the 1st-3d order of the coronary arteries and cardiac veins have been formed. Topography and main dimentions of large cardiac vessels are defined. During the prenatal period ramification zones of the coronary arteries do not change. In different age groups of the fetuses and newborns right coronary type of the cardiac blood supply predominates considerably (58-60%), in 27-32%--equal, and in 8-13%--left coronary type is observed. A great variability of the venous cardiac bed, vast intervenous anastomoses and a special importance of the cardiac middle vein in blood outflow are noted.
