Aneurysm is a bulge developed on the artery or blood vessel that supplies oxygenated blood to various organs. Aneurysms develop when because of the blood pressure at the sites of weakened and thin vessel walls. Aneurysms give an appearance of a balloon attached on the artery. Various genetic diseases, medical conditions or trauma may damage the artery walls making them weak and thin.

Arteriovenous Malformation (AVM)

Arteriovenous malformation (AVM) is an abnormal condition where the arteries and veins are tangled in a particular site resulting in impaired blood flow to the brain tissues around the AVM. Arteries and veins are interconnected to each other by several capillaries. These capillaries retard the flow of blood and helps in nourishing the cells and tissues with food, oxygen and other nutrients to the surrounding tissues.

Cavernous Angioma

Cavernous angioma also called cavernous malformation or cavernoma is a small mass of expanded blood vessels that appears like a berry. The condition is more common in children and may be present at birth. These malformations are supplied with blood from small low-flow blood vessels of the brain. The pressure caused by blood accumulation around the malformation may cause symptoms such as weakness, dizziness, headaches and seizures.

Moya Moya

This is a poorly understood disease of the major arteries at the base of the brain. Progressive narrowing is seen in the large arteries and in response to this, a network of fine vessels form in an attempt to maintain blood supply to the starved brain.
