The Neurosurgery team at Mercy treats a variety of cases, both common and rare. Some of the services include: Acoustic Neuroma - a tumor, usually benign, which develops on the hearing and balance nerves and can cause gradual hearing loss, tinnitus, and dizziness. Arteriovenous malformations - are blood vessel malformations. An AVM occurs when brain or spinal cord arteries attach directly to veins without the blood passing through the capillary network. AVM's can cause bleeding within the nervous system (a kind of stroke), or progressive neurologic deficits, headaches or seizures. They occur in a variety of brain locations, sizes and shapes. Cerebral Aneurysms - cerebral or brain aneurysm is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. A common location of cerebral aneurysms is on the arteries at the base of the brain, known as the Circle of Willis. Aneurysms may result from congenital defects, preexisting conditions such as high blood pressure and atherosclerosis (the buildup of fatty deposits in the arteries), or head trauma. Cervical and Lumbar herniated disc Epilepsy - a disorder of the brain that results in recurrent, unprovoked seizures. Gliomas - cancers of the brain and spinal cord which arise from glial, or supportive cells. Meningioma - type of tumor that occurs in the meninges, the membranes that cover and protect the brain and spinal cord. Metastatic Bone Disease - characterized by low bone turnover and low amounts of circulating parathyroid hormone. Normal amounts of mineralization occur in this type of disease, though osteoblast and osteoclast numbers are reduced. Neuro-angioplasty - the use of a small balloon on the tip of a catheter inserted into a blood vessel to open up an area of blockage inside the vessel. Peripheral nerve disorders, e.g. carpal tunnel syndrome - a condition characterized by pain and numbing or tingling sensations in the hand, caused by a compression of a nerve in the carpal tunnel at the wrist. Subdural Hematoma - is a blood clot that occurs on the surface of the brain and just below the dura (covering of the brain). A subdural hematoma usually occurs from the tear of one of the veins that drain the blood from the brain. Subdural hematomas can be either acute (after a recent injury), or chronic (after an old and sometimes forgotten, even minor or trivial head injury). Chronic subdural hematomas can be managed with close observation or if the blood clot is sizable, with drainage via burr holes. Spondylosis cervical and Lumbar spine - is the portion of the spine, commonly referred to as the small of the back. The lumbar portion of the spine is located between the thorax (chest) and the pelvis. Spinal instrumentation and fusion - is a method of keeping the spine rigid after spinal fusion surgery by surgically attaching hooks, rods, and wire to the spine in a way that redistributes the stresses on the bones and keeps them in proper alignment with the bones of the spine fuse. Tumors of the brain, pituitary gland and spinal cord.
