2019年10月30日 · The superior hypophyseal artery (or arteries) is a branch from the C6 segment of the internal carotid artery. It is usually a single trunk arising from the medial or posteromedial aspect of the internal carotid artery within 5 mm of the origin of the ophthalmic artery 2 .

Here is an example of superior hypophyseal artery (arrows) supplying the intracranial and optic canal portions of the nerve (dashed arrows). Any ischemia here (posterior ischemic optic neuropathy) would be quite obvious to the patient.

The superior hypophyseal artery is an artery supplying the pars tuberalis, the infundibulum of the pituitary gland, and the median eminence. It is a branch of the ophthalmic part of the internal carotid artery .

The Superior Hypophyseal Artery is defined as an artery that typically arises from the ophthalmic segment of the internal carotid artery, supplying blood to structures in the preinfundibular space and branching into infundibular, optic, and descending groups.

2018年7月13日 · The superior hypophyseal arteries (SHAs) are intimately related to lesions in the suprasellar space, such as craniopharyngiomas and meningiomas. Here the authors investigate the surgical anatomy and variations of the SHA from the endoscopic endonasal perspective.

The superior hypophyseal artery arises near the cavernous sinus. It then passes upwards to the medial eminence, and forms a primary plexus that provides the hypothalamic-portal circulation. Regions supplied by the superior hypophyseal artery include the pars tuberalis and infundibulum of the pituitary gland, the medial eminence of the floor of ...

The superior hypophyseal artery (SHA) arises from the posteromedial surface of the internal carotid artery just distal to the distal dural ring. This terminology was first used by Day ( 1 , 2 ). The SHA is responsible for the arterial supply of the pituitary stalk, optic nerves, and optic chiasm ( …

The superior hypophyseal arteries (SHAs) are well known in anatomical and surgical literature, with a well-established role in supply of the anterior hypophysis and superjacent optic apparatus. However, due to small size and overlap with other vessels, in vivo imaging by any modality has been essentially non-existent.

We performed a cadaveric microsurgical anatomical study of 20 internal carotid arteries between the ophthalmic and posterior communicating arteries to develop a better understanding of the anatomical relationships of the superior hypophyseal artery.

2025年1月17日 · This study aimed to provide an updated evidence of superior hypophyseal artery (SHA) aneurysms management, including their clinical implications, predictive factors for rupture, therapeutic approaches, and post-treatment outcomes.
