arterial territories refer to the specific regions of the brain that are supplied with blood by a particular artery or group of arteries
understanding the arterial territories is important for accurate diagnosis, localizing, and management of stroke

Anatomy of cerebral arteries

This chapter provides a summary of the fundamental aspects of cerebral vascular anatomy that are essential for stroke physicians and neurosonologists in their clinical practice.

Arteria lusoria

Unfavorable vascular anatomy during endovascular treatment

Unfavorable vascular anatomy refers to features that pose challenges or difficulties during endovascualr procedures. These challenges include arterial tortuosity, stenosis, calcifications, or variations in vessel configuration.

Anatomy of cerebral veins and dural sinuses

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.

Spinal cord arteries

Blood Supply of the Spinal Cord

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)

Extracranial anastomoses in ICA occlusion. Reverse flow is seen in the right ACA.

Cerebral collateral circulation

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