Cerebral arteriovenous malformation locations may stop the circulation of the cerebrospinal fluid, causing accumulation of the fluid within the skull and giving rise to a clinical condition called hydrocephalus. A stiff neck can occur as the result of increased pressure within the skull and irritation of the meninges. AVMs are an abnormal connection between the arteries and veins in the human brain. Arteriovenous malformations are most commonly of prenatal origin. In a normal brain oxygen enriched blood from the heart travels in sequence through smaller blood vessels going from arteries, to arterioles and then capillaries. Oxygen is removed in the latter vessel to
Anterior spinal veins dural fistulas can experience venous hypertension caused by thrombosis of these veins. The anterior spinal cord, which makes up 2/3 of the entire spinal cord, gets its blood supply from the anterior spinal artery. This artery in turn receives its blood from the different radiculospinal branches, which are formed from the aorta and vertebral arteries. As the largest of the radiculospinal artery branches, the Artery of Adamkiewicz provides a large amount of blood to the anterior spinal artery, thereby also supplying a good amount to the anterior spinal cord. There is a very limited availability to research the spinal venous
