Purpose: Investigate specific characteristic of blood supply of fetal vertebral bodies. Material & Methods: 16 - 30 week aged 20 fetuses (10 male, 10 female) were used for the study. Norms and requirements of Bio-Medical Ethics have not been violated in the use of human material in the study. Black-ink perfusion and cast of substance absorbing X-ray were applied in the fetuses. Results: Three concentric zones could be distinguished in the vascular architecture of the fetal vertebral bodies. 1) The peripheral zone of perichondrial vessels; 2) The intermediate zone of radial vessels. 3. The central zone of the ossification centre vessels. We used black-ink perfusion and cast of substance absorbing X-ray were applied in the fetuses. Periosteum of fetal vertebral bodies are distributed originating from fine arteries of 70 - 120diameter and arterioles of 30 - 50diameter which are part of arteries of network of micro blood circulation. Venules are followed along two sides of this arteriole and short precapillaries are branched out in tree-like manner from it forming capillary network surrounding arteriole and capillary plexuses. Postcapillaries branched from the network are being emerged the venules accompanied arterioles. Conclusions: Micro blood circulatory system of the vertebrae has angion structure. The peripheral zone of perichondrial vessels has combined blood supply surrounded by blindly ending capillary network drained up and down from the central zone. The central zone of vertebral body is supplied with blood by the main arteriole.
