Cerebral Oxygenation in Arterial Hypoxia [PDF]
, 1976 Pronounced increases in CBF occur in arterial hypoxia (see, for example Kety and Schmidt 1948, Cohen et al. 1967). The mechanisms of this hyperemia have never been clarified but it has been postulated that a decreased extracellular pH is responsible. The following evidence has been quoted in favour of this hypothesis. First, pronounced increases in CBF

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 ...

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

CerebroVis: Designing an Abstract yet Spatially Contextualized Cerebral Arteries Network Visualization [PDF]
, 2019 Blood circulation in the human brain is supplied through a network of cerebral arteries. If a clinician suspects a patient has a stroke or other cerebrovascular condition they order imaging tests. Neuroradiologists visually search the resulting scans for abnormalities.

Cerebral hemodynamic characteristics of acute mountain sickness upon acute high-altitude exposure at 3,700 m in young Chinese men. [PDF]
, 2014 PURPOSE: We aimed at identifying the cerebral hemodynamic characteristics of acute mountain sickness (AMS). METHODS: Transcranial Doppler (TCD) sonography examinations were performed between 18 and 24 h after arrival at 3,700 m via plane from 500 m (n ...

Blood supply of the internal capsule and basal nuclei [PDF]
Srpski Arhiv za Celokupno Lekarstvo, 2005 The internal capsule and basal nuclei are supplied by perforating branches of the anterior cerebral artery (ACA), Heubner's artery, middle cerebral artery (MCA), internal carotid artery (ICA) and anterior choroidal artery (AChA).

Posterior Cerebral Artery [PDF]
, 2011 From the caudal division of ICA arises the PcomA from which posteriorly develops progressively the PCA, and anteriorly and caudally a connection with BA. Later in evolution in the majority of the cases the connection of the PcomA with the PCA (also called pars carotica) regresses or becomes hypoplastic, while in the connection of the BA with the PCA ...
