Basilar artery fenestration | Radiology Reference Article - Radiopaedia.org
2022年4月22日 · Basilar artery fenestration (or more simply, basilar fenestration) is the most common intracranial arterial fenestration and most common congenital anomaly of the basilar artery. This anatomic variant is characterized by duplication of a portion of the artery that are connected proximally and distally.
Basilar artery | Radiology Reference Article - Radiopaedia.org
2023年1月8日 · The basilar artery is part of the posterior cerebral circulation. It arises from the confluence of the left and right vertebral arteries at the base of the pons as they rise towards the base of the brain. The basilar artery runs cranially in the central groove of the pons towards the midbrain within the pontine cistern.
Fenestrations of the Basilar Artery Demonstrated on Magnetic Resonance ...
Fenestration of the basilar artery (BA) is a rare variant of the intracranial artery, well demonstrated in autopsy and angiographic studies. Some angiographic series show a high incidence of associated aneurysms at the basilar fenestration site.
Basilar Artery Thrombosis - StatPearls - NCBI Bookshelf
2023年7月3日 · The basilar artery is formed by the convergence of the vertebral arteries at the junction of the pons and medulla. It provides oxygen-rich blood to the cerebellum, brainstem, thalamus, occipital, and medial temporal lobes of the brain. Basilar artery thrombosis is a devastating form of stroke with high morbidity and mortality.

2006年6月15日 · Basilar artery (BA) fenestrations are the most frequently observed variant of the cerebral arteries. We examined the magnetic resonance (MR) angiographic incidence, location, characteristic configuration of BA fenestration and associated vascular disease.
Magnetic resonance angiography evaluation of basilar artery ... - PubMed
To assess the usefulness of evaluating basilar arterial flow by magnetic resonance angiography (MRA), MRA results for patients with vertebrobasilar insufficiency (VBI) were compared with those for age-matched individuals with no vestibular disorders.
Basilar artery stenosis: Clinical and neuroradiographic features
2000年3月1日 · For 25 of the 28 patients, the diagnosis of BAS was made by using conventional cerebral angiography or a combination of MRA and TCD. The remaining 3 patients underwent only MRA (Table 2). The proximal basilar artery was the most common site for stenosis (13/28), followed by the mid-basilar artery (10/28), and distal basilar artery (3/28) segments.
Change in basilar artery length and bending according to aging …
2020年6月1日 · This study aimed to investigate the basilar artery (BA) geometric changes in a longitudinal study. 154 subjects with normal vertebrobasilar arterial systems on magnetic resonance angiography...
