Aim of the work is to study the local features of pleural structure as a system that provides circulation of serous fluid.
Material and methods. The article presents the results of the study of various topographic zones of the parietal and visceral pleura, diaphragmatic peritoneum. The original method of impregnation of total film preparations with silver nitrate followed by stereomicroscopy in reflected light was used (patent No. 2413943). The material was obtained from 29 corpses of mature persons.
Results. The conducted studies revealed topographic zones of the parietal pleura with the maximum concentration of drainage holes – the diaphragmatic pleura in the area of its tendon center and the costal pleura in the projection of intercostal muscles. These primary links in the pleural fluid drainage system are characterized by significant variability both in size (from 2-6 microns to several millimeters in diameter) and in shape. The internal structures of the holes in the form of trabecules and septal structures are described. They stabilize the lumen of drainage paths and ensure the circulation of serous fluid. Morphological data confirming the functional interaction between the microcirculation pathways of the diaphragmatic pleura and peritoneum were obtained.
Conclusion. The parietal leaf of pleura in its costal and diaphragmatic parts has specialized loci of a high degree of fenestration. Drainage holes as a structural and functional module of these pleural loci are the main way of reabsorption of serous fluid.
