Asymptomatic Common Carotid Artery Occlusion and Occipital-Vertebral Artery Anastomosis: A Case Report and Literature Review

Journal of the Korean Society of Radiology, 2023
Common carotid artery occlusion (CCAO) is a very rare disorder that has rarely been studied. CCAO causes several neurological symptoms but can sometimes be asymptomatic due to the development of various anastomoses.

Cirsoid Aneurysm of the Scalp: A Case Report

Indian Journal of Neurosurgery, 2016
Cirsoid aneurysms (arteriovenous malformations [AVMs]) of the scalp are rarely encountered in neurosurgical practice. Patients with AVM of the scalp present clinically at times with headache and a small innocuous-looking subcutaneous scalp lump or a ...

Persistent second cervical intersegmental artery diagnosed by MR angiography

Radiology Case Reports, 2019
Anastomosis between the external carotid and vertebral (VA) arteries is extremely rare. A well-recognized manifestation of such anastomosis is the Type 2 proatlantal artery, which commonly demonstrates anastomosis of the occipital artery with the VA at ...

Anatomical evaluation of the greater occipital nerve block using embalmed neonatal cadavers

Southern African Journal of Anaesthesia and Analgesia
Background: The greater occipital nerve block is indicated for pain relief in children undergoing, among others, posterior fossa craniotomies. This nerve, which arises from the C2 spinal nerve, travels alongside the occipital artery and provides ...

Ultrasound-guided greater occipital nerve block for patients with occipital headache and short term follow up [PDF]

Korean Journal of Anesthesiology, 2011
BackgroundThe greater occipital nerve (GON) block has been frequently used for different types of headache, but performed with rough estimates of anatomic landmarks. Our study presents the values of the anatomic parameters and estimates the effectiveness

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

14‐3‐3γ Protects Against Postoperative Cognitive Dysfunction by Regulating Tau Thr205 Phosphorylation and Synaptic Integrity

Advanced Science, EarlyView.
Integrative multi‐cohort analyses identify 14‐3‐3γ as a biomarker and regulator of cognitive vulnerability. Experimental studies show that 14‐3‐3γ loss is associated with Tau Thr205 phosphorylation, synaptic dysfunction, and cognitive impairment, while genetic overexpression or pharmacological stabilization of 14‐3‐3γ confers protective effects in ...
