HISTOMORPHOMETRIC COMPARISON OF DIAMETER OF RIGHT AND LEFT VERTEBRAL

open access: yesNational Journal of Medical Research, 2022
 Introduction: It is evident that slight changes in the diameter of a vessel cause tremendous changes in its ability to conduct blood when the blood flow is streamline. The conduction of vessel increases in proportion to the diameter.

VAST: Vertebral Artery Stenting Trial. Protocol for a randomised safety and feasibility trial

open access: yesTrials, 2008
Background Twenty to 30 percent of all transient ischaemic attacks and ischaemic strokes involve tissue supplied by the vertebrobasilar circulation. Atherosclerotic stenosis ≥ 50% in the vertebral artery accounts for vertebrobasilar stroke in at least ...

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Thoracic endovascular aortic repair in a case of grade III blunt aortic injury with aberrant vertebral artery origin

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2019
Aberrant origin of the left vertebral artery (LVA) can pose a challenge during thoracic endovascular aortic repair. We encountered such a patient who was involved in a motor vehicle accident in whom computed tomography angiography revealed a grade IIIB ...

Vertebral artery occlusion associated with blunt traumatic cervical spine injury

open access: yesAcute Medicine & Surgery, 2021
Aim Vertebral artery injury associated with blunt traumatic cervical spine injury sometimes causes severe cerebellar and brain stem infarction. No treatment guidelines for vertebral artery injury aimed at preventing stroke have been decided.

Trabecular bone ontogeny of the human talus

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Rotational vertebral artery occlusion secondary to completely extraosseous vertebral artery [PDF]

open access: yesJournal of Vascular Surgery Cases, Innovations and Techniques, 2019
Rotational vertebral artery (VA) occlusion is a possible cause of reduced blood flow through the posterior circulation of the brain due to compression of the VA on head turning when blood flow from the contralateral VA is compromised. When compression occurs in the V2 segment of the VA, it is usually due to compression from the longus colli muscle or ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

An investigation of a sympathetic innervation of the vertebral artery in primates: is there a neurogenic substrate for vasoconstriction?

open access: yesEuropean Journal of Histochemistry, 2009
Vasoconstriction of the vertebral artery may be neurogenic in origin. Although the existence of a perivascular sympathetic plexus of the vertebral artery is not in doubt, no method used to date has conclusively demonstrated a direct sympathetic ...
