title: [Microsurgical angioarchitectonics of depth structures of the brain and depth interarterial anastomoses].
abstract: The paper deals with the investigation studying the localization of a structure and showing the ways of formation of depth interarterial anastomoses of the brain. Three areas of deep interarterial anastomoses are identified, which are characterized by their symmetric pattern and formed by the arteries supplying blood to the deep cerebral structures and which create an epithalamic circle of anastomoses similar to the basal hypothalamic arterial circle of Willis. The existence of depth interarterial anastomoses points to the sole functional significance of depth structures of the brain. Depth epithalamic anastomoses are mechanisms that are responsible for the additional redistribution of blood from different vascular beds when cerebral blood flow is impaired in the depth structures and their presence should be taken into account during neurosurgical interventions.
