使用手术显微镜对 50 具成人尸体半球进行了从上方观察的垂体柄和腺体动脉的显微外科解剖学研究。从上方通向垂体的血管有三种：源自颈内动脉的垂体上动脉、源自后交通动脉的漏斗动脉和源自眼动脉的视交叉前动脉。垂体上动脉起源于颈内动脉的内侧至后侧。垂体上动脉平均每个半球2.2条，直径平均0.25mm。大多数（76%）垂体上动脉起源于颈内动脉眼动脉和后交通动脉起点之间的近端半段。漏斗动脉主要起源于后交通动脉的内侧（69%）。其直径为0.22毫米，每个半球的数量为0.23个。每个半球视交叉前动脉的数量为0.06。结果，每个半球平均有2.5条血管，每个大脑总共有5条血管，平均直径为0.25毫米，从上方供给垂体柄和腺体。讨论了这些解剖数据在鞍上肿瘤和颈动脉眼动脉瘤的诊断和治疗中的临床应用。
The microsurgical anatomy of the arteries of the pituitary stalk and gland as viewed from above was studied in 50 adult cadaveric hemispheres using the operating microscope. There were three types of vessels to the pituitary from above: the superior hypophyseal artery originating from the internal carotid artery, the infundibular artery from the posterior communicating artery, and the prechiasmal artery from the ophthalmic artery. The superior hypophyseal artery originated from the medial to posterior aspect to the internal carotid artery. The average number of vessels of the superior hypophyseal artery was 2.2 per hemisphere, and the diatmeter was 0.25 mm on average. The majority (76%) of superior hypophyseal arteries arose from the proximal half of the segment between the origins of the ophthalmic and posterior communicating arteries of the internal carotid artery. The infundibular artery originated mainly from the medial side (69%) of the posterior communicating artery. Its diameter was 0.22 mm, and number 0.23 per hemisphere. The number of prechiasmal arteries was 0.06 per hemisphere. As a result, there were on average 2.5 vessels per hemisphere, totally 5 per brain, with the average diameter 0.25 mm, supplying the pituitary stalk and gland from above. The clinical application of these anatomical data to the diagnosis and treatment of suprasellar tumours and carotid-ophthalmic aneurysms is discussed.
