✓ A technique for the removal of sphenoid blocks from cadavers and for selective injection of the hypophyseal arteries of these specimens is described. Results of such injections are presented, with emphasis on the role of the inferior hypophyseal artery (IHA). The IHA was found to be the most important artery supplying the pituitary gland, and in particular, the structures involved in production, transportation, and storage of the antidiuretic hormone. The literature pertinent to the arterial blood supply of the normal pituitary gland is reviewed.

Secondary Phenomenon

ABSTRACT From a histological study of the lesions which develop in the vessels of the human pituitary gland during the first two days after the onset of post-partum necrosis of the anterior lobe, it is concluded that the primary vascular disturbance is a spasm involving the arteries which supply the anterior lobe and the stalk. This arrests the portal blood supply and also the direct arterial blood supply to the lobe, but permits a slight circulation to continue in the stalk. If the spasm is relieved within about an hour the parenchyma suffers only a transient functional damage. If it continues for several hours all the tissues in the anterior lobe are killed and, when blood finally attempts to flow into the dead vessels, stasis and thrombosis occurs. This thrombosis is a secondary phenomenon and is not the cause of the necrosis. Variations in the extent and the duration of the spasm account for the variations in the size of the necrosis; in about half the cases the lesion involves 97 to 99 per cent of the anterior lobe, but the pars tuberalis and a small amount of the pars interloralis always survive. The arterial spasm is certainly related to a severe general circulatory collapse at the time of delivery, but the reason for its very specific localisation to the anterior lobe of the pituitary gland remains obscure.

The vascular pathways of the pituitary gland in the donkeys was studied. The contribution of the arterial blood supply of the pituitary gland was described. It was found that the portal vessels of the pituitary gland were originated from the vascular arches, which is found between the pars tuberalis and the infundibulum. These vessels have different extensions and branched in different regions of the anterior lobe of the pituitary gland.

The review of national and foreign literature sources presents information on arterial blood supply of the umbilical region in newborns having relevant practical significance due to the development of new surgical approaches in that part of the anterior abdominal wall. Scientific data on the course and location of arteries participating in the blood supply of the umbilical region are summarized. Particular attention is devoted to the description of superficial, superior and inferior epigastric arteries and umbilical arteries. The issues of intervascular connections between the named arteries and other blood vessels are discussed including information on various anastomosis variations and their extent. Various existing viewpoints regarding the location and depth of anastomoses between the vessels essential for blood supply of the umbilical region are presented as well as the layers, through which the main arteries pass, and the character and level of their branching. Features of arterial blood supply of the umbilical region in newborns are also noted. The paper contains data on the role of umbilical arteries in the umbilical region supply in children of that age. It is demonstrated that blood supply of the umbilical region in newborns still poses issues that are insufficiently researched and solved, such as assessing functional capacity of the umbilical arteries, revealing histotopographic peculiarities in the location of blood vessels within the layers and various segments of the umbilical region, topographic and anatomic identification of the segments that are most and least supplied with arterial vessels in that part of the abdominal wall.
