Aneurysm is an abnormal bulging along an artery or blood vessel wall. Aneurysms occur from blood pressure at places with deteriorated or thin vessel walls. Aneurysms appear like a balloon bulging out from the outer wall of the artery. Numerous genetic diseases, medical conditions or trauma may injure the artery walls making them feeble and thin.
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 carry oxygenated blood from the heart to different parts of the body. Veins carry de-oxygenated blood from the tissues back to the heart. 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, also known as cavernous malformation or cavernoma, is a tiny mass of extended blood vessels that appear like a berry. The disorder is more common in children and may be present at birth. These deformities are furnished with blood from small low-flow blood vessels of the brain. The pressure triggered by blood buildup around the distortion may cause symptoms such as weakness, dizziness, headaches and seizures.
This is an inadequately known disease of the main arteries at the base of the brain. Advanced contraction is seen in the large arteries and in reaction to this, a grid of fine vessels form in an effort to sustain 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.
