Arterial territories

Variants in the arrangement of cerebral vessels are quite common. They often have low clinical significance, but their knowledge and recognition are fundamental if surgical or endovascular treatment is considered.

Topical diagnosis in stroke refers to the localization of ischemia based on clinical signs and symptoms and advanced imaging modalities. Accurate topical diagnosis is essential for timely and targeted intervention and can help determine the etiology of stroke and initiate appropriate secondary stroke prevention.

The cerebral veins drain the brain parenchyma into the dural venous sinuses and from there into the internal jugular veins. They are characterized by thin walls lacking muscular tissue and valves.

The brain is supplied by the internal carotid arteries and vertebral arteries. They form, together with their branches, the circle of Willis.

The collateral cerebral circulation is a network of blood vessels that helps maintain stable blood flow in the brain when a main artery is stenosed or occluded.

The arterial blood supply of the spinal cord is secured via three longitudinal arteries - a single anterior spinal artery (ASA) and the two posterior spinal arteries (PSA)
