Intracranial Arterial Diseases
| Definition: |
Conditions which affect the arteries of the brain, meninges, and intracranial portions of the cranial nerves. Relatively common disease processes in this category include: ATHEROSCLEROSIS; emboli; thrombosis (INTRACRANIAL EMBOLISM AND THROMBOSIS); VASCULITIS, CENTRAL NERVOUS SYSTEM; CEREBROVASCULAR TRAUMA; vasospasm (VASOSPASM, INTRACRANIAL); INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; and infections. |

Intracranial Arterial Diseases Categories.
 |
Cerebral Arterial Diseases - Diseases of intracranial arteries which supply the cerebrum of the brain, including the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY. Included in this category are atherosclerotic, congenital, traumatic, infectious, inflammatory, and other conditions. |
|
Intracranial Arteriovenous Malformations - Congenital vascular anomalies of the brain characterized by tangles of thin walled arteries which communicate directly with veins without intervening capillaries. The malformations vary greatly in size and location, and produce symptoms through rupture (see also INTRACRANIAL HEMORRHAGES), mass effect, and vascular steal effect. Clinical presentation is often delayed until the fourth or fifth decade when affected individuals may develop headaches, seizures, and focal neurologic deficits. Large hemorrhages may result in coma or death. (From Adams et al., Principles of Neurology, 6th ed, p848) |
