Minimally Invasive Spine Surgery for Lumbar Decompression or Disc Herniation.

Many people experience low back pain caused by degenerative disease of the lumbar spine; this includes spinal stenosis, spondylolisthesis, disc degeneration, and disc herniation. Conservative management of degenerative disease, which includes physical therapy, lifestyle modifications, and medications, is the initial approach. If this approach fails, a surgical procedure may be the next step.

Encephaloduroarteriosynangiosis Procedure: A Treatment Option for Patients With Moyamoya Disease.

Moyamoya disease is a progressive cerebrovascular disorder for which there is no cure. It is characterized by narrowing of and occlusions in the blood vessels that supply the brain, which causes a fine vascular network to develop to serve as collateral pathways. Moyamoya disease can lead to a reduction of blood flow to the brain and increase the risk of stroke.

Robotic-Assisted Lumbar Fusion: An Effective Technique for Pedicle Screw Placement.

Degenerative lumbar disease is a common condition in which progressive deterioration of the structures in the spine causes severely incapacitating pain and disability. Conservative management, including passive or active physical therapy, activity modification, and medications (eg, anti-inflammatory medications, oral and injectable steroids, opioids), may provide relief. However, when conservative management is unsuccessful or patients experience symptoms for an extended period of time, they may require spine surgery.

Care of the Patient Undergoing Robotic-Assisted Brain Biopsy With Stereotactic Navigation: An Overview.

Brain tumors can cause pressure, swelling, and functional changes to the surrounding tissue and lead to sensorimotor symptoms. Such tumors are either benign or malignant and their origin can be primary or metastatic. Although diagnostic studies (eg, computed tomography and magnetic resonance imaging) can reveal a mass and provide information on its location, size, and relationship to surrounding structures, the most definitive way to make a diagnosis requires a brain biopsy tissue sample.

Laparoscopic-Assisted Ventriculoperitoneal Shunt Placement: A Less Invasive Approach to Treating Hydrocephalus.

Hydrocephalus is caused by the disruption of the normal flow of cerebrospinal fluid (CSF), which results in a buildup of CSF. Hydrocephalus comprises two key categories: communicating and noncommunicating. Normal-pressure hydrocephalus, a type of communicating hydrocephalus, currently has no cure; the main treatment option is ventriculoperitoneal shunt (VPS) placement surgery.

Decompressive Hemicraniectomy for Middle Cerebral Artery Stroke: Indications and Perioperative Care.

Decompressive hemicraniectomy (DHC) is a procedure performed in the setting of malignant cerebral edema after a large middle cerebral artery stroke. The decision to proceed with surgical decompression is one that must be made judiciously and rapidly. Although this can be a life-saving surgery, it does not necessarily improve the patient's quality of life.
