[Angioarchitectonics of the costovertebral joints of embryos, fetuses, and newborn infants].
Blood supply of the costo-vertebral joints has been studied in human embryos (18), fetuses of various age (83) and newborns (4). Methods of preparation, circulatory bed injection with various contrasting masses--for roentgenography and Indian ink with gelatin suspension--for microscopic investigations have been applied. Histological sections (both sagittal and horizontal) have been stained after van Gieson. At the end of the 8th week of development the main sources of blood supply for the human costo-vertebral joints are branches of the segmental arteries, and at the end of the 12th week--those of the subclavian artery (the highest intercostal artery and the deep cervical artery) and those of the thoracic aorta (10 pairs of the posterior intercostal arteries). In the fetuses, variations in the course of the intercostal arteries have been revealed. The arteries situating within the costo-vertebral joints form extra organic branches which participate in blood supply of ligaments, articular capsules and cartilagenous epiphyses. Peculiar features in the angioarchitectonics of structural components of the costo-vertebral joints have been demonstrated. Interrelations of the blood vessels with some tissues of the costal head joint and the costo-transversal joints have been stated. The course and direction of capillaries in the cartilagenous tissue of the head, cervix and costal tubercle, and also in the transversal processes of the thoracic vertebrae have been described. No blood vessels have been revealed in the cartilage of the costo-vertebral joints.
