Blood Vessel Conditions

Aneurysm

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.

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.

Microvascular Decompression for Trigeminal Neuralgia

Trigeminal Neuralgia is a disorder of the trigeminal nerve which at times causes intense pain in the face. This procedure involves having a small cut made behind the ear on the same side as the pain. A small amount of bone will be removed from the skull. A microscope is then used to identify the trigeminal nerve and the blood vessels compressing the nerve. Once this is done the surgeon will place some protective cushioning (usually Teflon) between the vessel and the nerve to ensure separation. The removed bone will be replaced with metallic plates and screws. The skin will be closed with sutures.
