PRECAPILLARY arteriovenous anastomoses are a normal part of the microcirculatory bed of skin, muscle, lung, heart, intestine, liver, spleen, kidney, ear, and eye. 1,2 These have been labeled "preferential channels" 3 or "throughfare channels" by Chambers and Zweifach. 4 Whether similar anastomoses occur in the brain parenchyma has been a subject of debate. Rowbotham and Little 5-9 observed precapillary arteriovenous anastomoses in the pial circulatory system but not in the brain parenchyma of… Expand
Cerebral Arteriovenous Shunts Re‐examined
TLDR
The conclusion of this study is that structural, noncapillary A-V shunting definitely occurs, but is very small and variable in amount. Expand
Do microemboli reach the brain penetrating arteries?
TLDR
Rat brain has an impressive tolerance to microemboli, although this clearly varies with emboli size and number, and Wash out of particulates through AV connections is not a major factor in brain tolerance in this model. Expand
Investigations on the filter capacity of the dog's brain. A contribution to the question of cerebral arteriovenous shunts.
TLDR
In 28 dogs with controlled ventilation and circulation, the passage of microspheres injected into the carotid in size ranges from 1μ to 100μ through the brain was observed, and the presence in the dog's brain of arteriovenous connections much larger than capillaries, but not larger than 76μ, is postulated.

Pial Microcirculation in Subarachnoid Hemorrhage
TLDR
Microsurgical and microscopic methods were employed in guinea pigs to expose, observe, and measure response characteristics of cerebral cortical pial microvessels and microcirculation to traumatic and nontraumatic experimental subarachnoid hemorrhage, finding that observed microcirculatory flow characteristics were consistent with those known to be associated with cerebral cortical infarction.

Cerebral arteriovenous malformations. Part 2: physiology.
TLDR
The dynamic nature of brain AVMs is at least in part attributable to hemodynamic and flow-related phenomena, and forces acting on an evolving structure are critical to understanding the challenges in endovascular and surgical therapy. Expand
Anatomical Analysis of the Developing Cerebral Vasculature in Premature Neonates: Absence of Precapillary Arteriole-to-Venous Shunts
TLDR
An autopsy study, involving 33 cases of premature neonates, concludes that precapillary arteriole-to-venous shunts are not a significant factor leading to GMH. Expand
Cortical blood vessels of the human brain
TLDR
Problems in distinguishing between arteries and veins, the geometric disposition of cortical vessels, different types of anastomoses and particular vascular features whose significance remains unclear, are discussed. Expand
Angioarchitecture of the CNS, pituitary gland, and intracerebral grafts revealed with peroxidase cytochemistry
TLDR
Blood vessels of the fetal, neonatal, and adult subprimate and primate CNS, including circumventricular organs, and of solid CNS and nonneural allografts placed within brains of adult mammalian hosts were visualized with peroxidase cytochemistry applied. Expand
The vascularization of the human cerebellar cortex
TLDR
The blood vessels of the cerebellar cortex were studied by two methods of injection: india-ink and low viscosity resin (Mercox) and accorded particular attention to the vascularization of the Purkinje cells. Expand
Red venous blood: occurrence and significance in ischemic and nonischemic cerebral cortex.
TLDR
Red cerebral venous blood has been noted in human cerebral cortex in veins draining cystic or scarred areas and in animals in regions of brain made ischemic by occlusion of a middle cerebral artery. Expand

  • E. Craigie

  • Biological reviews of the Cambridge Philosophical Society
  • 1945
TLDR
The capillary bed of the central nervous system may be either reticular or composed of independent loops, and there is an irregular trend towards increased vascular richness and greater differentiation in the supply of‐specific regions as the phylogenetic scale is ascended. Expand
THE CEREBRAL CIRCULATION: XIII. THE QUESTION OF END-ARTERIES OF THE BRAIN AND THE MECHANISM OF INFARCTION
TLDR
Cohnheim first clearly enunciated the theory that infarcts could occur only where there was no anastomosis between arteries, and impressed the medical world with the idea that unless "end-arteries" supplied an organ, or part of anorgan, no infarction could occur. Expand
The Brain Vascular System
TLDR
The authors find that the distribution of the arteries in the newborn is comparable to the adult, the most common change being the relative dependence on the mesencephalic artery by the posterior cerebral artery as a major source of blood for the posterior portion of the cerebral hemisphere. Expand
THE FATE OF RADIOACTIVE EMBOLI INJECTED INTO THE CEREBRAL CIRCULATION, THE BRAIN AS A FILTER
TLDR
The brain seemed to us a reasonably favorable organ for preliminary trials, due to the relative ease of puncturing any one of its 4 main nutrient arteries, the possibility of precise localization of a tumor in one or more of the arterial fields of supply, and the absence of metastases in gliomas.

The Blood Vessels of the Nervous Tissue
TLDR
In a tissue whose activity depends so much upon its blood supply, the microanatomical relations between the cells and the blood vessels are of particular interest and are reviewed here on the basis of recent work in this field. Expand
VARIATION IN VASCULARITY AND OXIDASE CONTENT IN DIFFERENT REGIONS OF THE BRAIN OF THE CAT
It has long been recognized that there is considerable variation in the amount of capillary bed available in different parts of the nervous system. However, only comparatively recently (following theExpand

TLDR
The vascular anatomy of the dura mater is described in detail as its peculiarities throw light on the actiology and vascularization of the meningiomata, a class of tumours that has played a large part in the moulding of the techniques of neurosurgery. Expand
