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...]

Tumors of Spine

TUMORS OF SPINE A spinal tumor is an abnormal mass of tissue within or surrounding the spinal cord and/or spinal column. These cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. Spinal tumors can be benign (non-cancerous) or malignant (cancerous). Primary tumors originate in the spine or spinal cord, and metastatic or secondary tumors result from cancer spreading from another site to the spine. Spinal tumors may be referred to by the region of the spine in which they occur. These basic areas are cervical, thoracic, lumbar and sacrum. Additionally, they also are classified [Read More...]

Spinal Stenosis

SPINAL STENOSIS Spinal stenosis is a narrowing of the spaces within your spine, which can put pressure on the nerves that travel through the spine. Spinal stenosis occurs most often in the lower back and the neck. Some people with spinal stenosis may not have symptoms. Others may experience pain, tingling, numbness and muscle weakness. Symptoms can worsen over time. Spinal stenosis is most commonly caused by wear-and-tear changes in the spine related to osteoarthritis. In severe cases of spinal stenosis, doctors may recommend surgery to create additional space for the spinal cord or nerves. Types of Spinal Stenosis [Read More...]

Cervical Disc Herniation

CERVICAL DISC HERNIATION A herniated disc occurs when the gel-like center of a spinal disc ruptures through a weak area in the tough outer wall, similar to the filling being squeezed out of a jelly doughnut. Neck or arm pain, numbness or tingling may result when the disc material touches or compresses a spinal nerve. Treatment with rest, pain medication, spinal injections, and physical therapy is the first step to recovery. Most people improve in 6 weeks and return to normal activity. If symptoms continue, surgery may be recommended. Symptoms of a herniated disc vary greatly depending on the [Read More...]

Lumbar Disc Herniation

LUMBAR DISC HERNIATIONA herniated disk is a condition that can occur anywhere along the spine, but most often occurs in the lower back. It is sometimes called a bulging, protruding, or ruptured disk. It is one of the most common causes of lower back pain, as well as leg pain or “sciatica.”Between 60% and 80% of people will experience low back pain at some point their lives. Some of these people will have low back pain and leg pain caused by a herniated disk.Although a herniated disk can be very painful, most people feel much better with just a [Read More...]

Algology

ALGOLOGYA brain tumor is a mass or growth of abnormal cells in your brain. Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant). Brain tumors can begin in your brain (primary brain tumors), or cancer can begin in other parts of your body and spread to your brain (secondary, or metastatic, brain tumors). How quickly a brain tumor grows can vary greatly. The growth rate as well as location of a brain tumor determines how it will affect the function of your nervous system. Brain tumor treatment options [Read More...]
