2023年10月30日 · Owing to the high oxygen and nutrient demand of the organ, it is supplied by two arterial systems: The posterior circuit is supplied by the vertebrobasilar system. The focus of this article will be to discuss the major arteries that supply the brain.

2024年9月30日 · Key components of the brain’s vascular system include arteries that deliver oxygen-rich blood, veins that carry away deoxygenated blood, and the minuscule capillaries that bridge the gap between the two.

2023年7月24日 · Awareness of its normal anatomy and its common variations and anomalies are critical for the diagnostic and treatment of stroke and associated vascular disorders. The brain vasculature provides the nutrients necessary for the well functioning of …

2024年3月31日 · There are two paired arteries which are responsible for the blood supply to the brain; the vertebral arteries, and the internal carotid arteries. These arteries arise in the neck, and ascend to the cranium. Within the cranial vault, the terminal branches of these arteries form an anastomotic circle, called the Circle of Willis.

Cerebral venous anatomy can be divided into the cerebral and posterior fossa anatomical compartments, both illustrated in Model 9. The cerebral venous configuration can be subdivided into a deep (subependymal) and superficial group.

In this paper, which is the first in a three-part series that reviews cerebrovascular anatomy, pathogenesis, and stroke, we lay the anatomical foundation for the rest of the series. Beginning with its origin in the branches of the aorta, we start by describing the arterial system.

Venous outflow from the cerebral hemispheres consists of two groups of valveless veins, which allow for drainage: the superficial cortical veins and the deep or central veins (Figure 4). The superficial cortical veins are located in the pia matter on the surface of the cortex and drain the cerebral cortex and subcortical white matter.
