2022年6月2日 · The inferior hypophyseal artery is a branch from the meningohypophyseal trunk, a branch of the C4 segment of the internal carotid artery. It is usually single on each side and divides into superior and inferior branches, anastomoses with its counterparts from the opposite, contributing to the inferior hypophyseal arterial circle 5,6 .

The inferior hypophysial artery is an artery in the head. It is a branch of the cavernous carotid artery, itself from the internal carotid artery. It supplies the posterior pituitary of the pituitary gland.

2022年2月23日 · The inferior hypophyseal arterial circle, also known as the inferior capsular arterial rete, is an anastomotic arterial network formed around the base of the pituitary gland by branches from three vessels, themselves branches off the cavernous portion of the carotid artery. They are: inferior hypophyseal artery (from the meningohypophyseal trunk)

Same artery — later arterial phase demonstrates a pituitary blush — inferior hypophyseal artery would be the source. No distinct MHT component vessels are visualized. Variability is the rule, and parts of the MHT may be visible in various non-pathologic circumstances.

More superior / inferior hypophyseal balance. Excellent example of contralateral balance. On the left, there is a hypoplastic posterior hypophyseal network (part of MHT, arrowhead), and a prominent superior hypophyseal artery (associated with a small aneurysm).

The inferior hypophyseal artery is defined as a branch that arises from the meningohypophyseal trunk or directly from the cavernous carotid artery, supplying the posterior lobe and capsule of the pituitary gland with blood. AI generated definition based on: Meningiomas, 2010

The inferior hypophysial artery, branch of cavernous part of internal carotid artery, supplies the neurohypophysis by forming a ring around it. It anastomoses with the superior hypophysial artery.

2024年11月29日 · OBJECTIVE The inferior hypophyseal arteries (IHAs) are intimately related to pituitary and cavernous sinus (CS) lesions. There is still no anatomical study specifically analyzing the IHAs. The aim of this study was to investigate the surgical anatomy and variations of the IHA, and to translate this knowledge into surgical practice.

Selective injection of the inferior and superior hy- pophyseal arteries, followed either by histological serial sec- tioning or by clearing of the complete block of tissue. This method consisted of the injection of all the arteries in the cranial cavity, and the subsequent removal of the hypophyseal block.

Objective: The inferior hypophyseal arteries (IHAs) are intimately related to pituitary and cavernous sinus (CS) lesions. There is still no anatomical study specifically analyzing the IHAs.
