title: [Microsurgical anatomy of extraorganic arteries of the hypothalamo-hypophyseal complex and the rational technic of its removal for transplantation].
abstract: The authors ascertained the existence of numerous anastomoses between the right and left hypophyseal arteries on the level of both the interlobar sulcus and the base of the hypophyseal funnel in the form of an inferior and superior hypophyseal anastomotic rings, as well as a system of arterial connections between the anterosuperior and anteroinferior subgroups of the hypothalamic arteries located in front of and lateral to the chiasma as prechiasmal networks. This creates anatomo-physiological preconditions for adequate circulation in the hypothalamo-hypophyseal graft after its transplantation and inclusion in the blood flow of the internal carotid artery or one of its terminal branches. Bearing in mind the close connection of the hypophyseal and hypothalamic arteries with the cavernous sinuses, chiasma, and components of the sella turcica, the hypothalamo-hypophyseal graft must be removed in a complex with these structures.
