Carotid Endarterectomy

CAROTID ENDARTERECTOMY The carotid arteries are the main blood vessels that carry oxygen and blood to the brain. In carotid artery disease, these arteries become narrowed. This reduces blood flow to the brain and could cause a stroke. Carotid endarterectomy (CEA) is surgery to treat carotid artery disease. During a carotid endarterectomy, we can surgically remove plaque that builds up inside the carotid artery. This is usually because a blood clot forms and a piece breaks off and goes to the brain. If a narrowed carotid artery is untreated, blood flow to the brain may be affected. This can [Read More...]

Arteriovenous Malformation

ARTERIOVENOUS MALFORMATION An arteriovenous malformation (AVM) is an abnormal tangle of blood vessels connecting arteries and veins, which disrupts normal blood flow and oxygen circulation. Arteries are responsible for taking oxygen-rich blood from the heart to the brain. Veins carry the oxygen-depleted blood back to the lungs and heart. When an AVM disrupts this critical process, the surrounding tissues may not get enough oxygen, and the affected arteries and veins can weaken and rupture. If the AVM is in the brain and ruptures, it can cause bleeding in the brain (hemorrhage), stroke or brain damage. An arteriovenous malformation can [Read More...]

Brain Aneurysm

BRAIN ANEURYSM A brain aneurysm is a bulge or ballooning in a blood vessel in the brain. It often looks like a berry hanging on a stem. A brain aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke). Most often a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a subarachnoid hemorrhage. A ruptured aneurysm quickly becomes life-threatening and requires prompt medical treatment. Most brain aneurysms, however, don't rupture, create health problems or cause symptoms. Such aneurysms are often detected [Read More...]

Signs & Symptoms

SIGNS & SYMPTOMS The signs and symptoms of cerebrovascular disease or a cerebrovascular attack depend on where the blockage or damage occurs, and how much cerebral tissue is affected. Different events may have different effects, but common signs and symptoms include: - A severe and sudden headache - Paralysis of one side (hemiplegia) - Weakness on one side (hemiparesis) - Confusion - Difficulty communicating, including slurred speech - Loss of half of vision - Loss of balance - Loss of consciousness

Cerebrovascular Disease

CEREBROVASCULAR DISEASE The word cerebrovascular is made up of two parts – "cerebro" which refers to the large part of the brain, and "vascular" which means arteries and veins. Together, the word cerebrovascular refers to blood flow in the brain. The term cerebrovascular disease includes all disorders in which an area of the brain is temporarily or permanently affected by ischemia or bleeding and one or more of the cerebral blood vessels are involved in the pathological process. Cerebrovascular disease includes stroke, carotid stenosis, vertebral stenosis and intracranial stenosis, aneurysms, and vascular malformations. Restrictions in blood flow may occur [Read More...]
