Distal anterior cerebral artery aneurysm with bilateral fetal posterior cerebral arteries and trifurcation of anterior cerebral artery

Indian Journal of Pathology and Microbiology, 2020
Developmental vascular anomalies of brain are non-modifiable risk factors for the development of aneurysms and are prone for rupture. We report one such association in a 44-year-old gentleman who succumbed to subarachnoid hemorrhage (SAH) secondary to ruptured distal anterior cerebral artery aneurysm associated with vascular anomalies in the anterior ...

Relationship between oxygen supply and cerebral blood flow assessed by transcranial Doppler and near-infrared spectroscopy in healthy subjects during breath-holding [PDF]

, 2006
Background Breath – holding (BH) is a suitable method for inducing cerebral vasomotor reactivity (VMR). The assessment of VMR is of clinical importance for the early detection of risk conditions and for the follow-up of disabled patients.

Narrowings of the Deep Cerebral Perforating Arteries Ostia: Geometry, Structure, and Clinical Implications [PDF]

Journal of Stroke
Background and Purpose The pathogenesis of neurovascular diseases and various types of dementia is tightly connected to cerebral circulation. An area that requires further exploration is the system of deep cerebral perforating arteries—arteries branching

Association of tetralogy of Fallot with multiple variations of the cerebral arteries diagnosed by magnetic resonance angiography

Radiology Case Reports, 2020
Tetralogy of Fallot very rarely manifests with variations of the cerebral arteries, but we detected an extremely rare combination comprising 3 such variants –bilateral carotid–anterior cerebral arteries anastomoses, the vertebral–anterior inferior ...

Anomalous origin of a middle cerebral artery from anterior cerebral artery with no association to an accessory or duplicated middle cerebral artery

Interdisciplinary Neurosurgery, 2022
The middle cerebral artery (MCA) is one of the major paired intracranial arteries involved in the formation of the circle of Willis. MCA is the most complex of the intracranial arteries mainly because it supplies the cerebral neocortex, which has been ...

Pulsatility of Lenticulostriate Arteries Assessed by 7 Tesla Flow MRI—Measurement, Reproducibility, and Applicability to Aging Effect

Frontiers in Physiology, 2017
Characterization of flow properties in cerebral arteries with 1.5 and 3 Tesla MRI is usually limited to large cerebral arteries and difficult to evaluate in the small perforating arteries due to insufficient spatial resolution. In this study, we assessed

Separation of cortical arteries and veins in optical neurovascular imaging [PDF]

Journal of Innovative Optical Health Sciences, 2014
Separation of arteries and veins in the cerebral cortex is of significant importance in the studies of cortical hemodynamics, such as the changes of cerebral blood flow, perfusion or oxygen concentration in arteries and veins under different pathological

An automated multiscale ensemble simulation approach for vascular blood flow [PDF]

, 2015
Cerebrovascular diseases such as brain aneurysms are a primary cause of adult disability. The flow dynamics in brain arteries, both during periods of rest and increased activity, are known to be a major factor in the risk of aneurysm formation and ...

Multiple blood flow measurements before and after carotid artery stenting via phase-contrast magnetic resonance imaging: An observational study. [PDF]

PLoS ONE, 2018
After carotid artery stenting, the procurement of information about blood flow redistribution among brain-feeding arteries and its time trend is essential to understanding a patient's physiological background and to determine their care regimen. Cerebral
