Carotid Artery Intervention

open access: yes, 2007
Atherosclerotic carotid artery disease is a major contributor to the incidence of stroke, particularly in the elderly. Atherosclerosis is a systemic illness and patients often present with multisystem involvement of several vascular beds including coronary, cerebral, and peripheral vascular territories. The majority of strokes related to carotid artery

Clot Composition Profiling in Large Vessel Occlusion Stroke Via Radiomics

open access: yesAnnals of Neurology, EarlyView.
Objective Clot composition may offer insights into the mechanism of ischemic stroke. Radiomics, a noninvasive imaging technique, enables tissue characterization through radiomic features (RFs). We aimed to evaluate clot composition using radiomics on non‐contrast computed tomography (NCCT).

Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Coiled Internal Carotid Arteries Associated with Bilateral Sequential Strokes

open access: yesCase Reports in Vascular Medicine, 2013
The risk of stroke and management of coiling of the cervical internal carotid artery in the absence of an atherosclerotic carotid bulb lesion is unclear.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

open access: yesThe Anatomical Record, EarlyView.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Using MSCT to Diagnose and Categorize High Bifurcation of the Common Carotid Artery Before Carotid Endarterectomy in Older Individuals

open access: yesРоссийский журнал гериатрической медицины
Carotid endarterectomy (CEA) is the mainstay of treatment for carotid artery stenosis for the prevention of ischemic strokes. The variant anatomy of the structure of the brachiocephalic arteries, namely the high bifurcation of the common carotid artery ...
