功能神经外科

推荐最近最火的赌博软件's neurosurgeons treat movement disorders 和 intractable pain with procedures specifically aimed at altering the activity of the abnormal neural circuits. Medical intractable movement disorders, such as those associated with 帕金森病, essential tremor 和 肌张力障碍, are amenable to such modulation.

Deep Brain Stimulation (DBS) or small ablations deep within the brain: Our neurosurgeon will place active electrodes deep within the brain with precise targeting to ensure that the activity of the appropriate nerve cells is altered for optimal results. Stereotactic techniques 和 electrophysiological monitoring (usually with microelectrodes) are used to obtain the necessary degree of precision.

To manage severe medically-intractable spasticity, secondary to cerebral palsy, multiple sclerosis or spinal cord injury, our neurosurgeons can implant pumps that deliver anti-spacticity medication intrathecally or directly around the spinal cord. 选择性背根切断术 is an alternative therapy that is also offered for spacticity.

攻击痛苦

Intractable pain can be treated with procedures that alter the activity of the central nervous system. Stimulation of the dorsal spinal column, thalamus or motor cortex can modulate 和 control pain impulses. A neurosurgeon can implant intrathecal drug pumps that deliver medications directly to the pain-producing circuits. This is useful in a wide variety of painful conditions, including those seen in patients with severely degenerated spines.

Selective ablations can can also interrupt the painful impulses. Examples include dorsal spinal cord (DREZ) lesions for pain after plexus injuries, anterolateral cordotomy for cancer pain 和 trigeminal radiofrequency ganglioysis, microballoon compression or Gamma Knife radiosurgery for treatment of 三叉神经痛.

Seizure disorders patients whose disabling seizures fail to respond to medication may be c和idates for surgical intervention. The patient is evaluated by a multidisciplinary team relying heavily on video EEG monitoring, high resolution MRI functional imaging, 和, 根据需要, EEG recordings with implanted intracranial electrodes. These technologies can often locate the epileptogenic tissue that is not apparent on traditional CT scans or MRIs.

When pharmacological treatment of seizures is ineffective, certain surgical procedures are available including partial temporal lobotomy, resection of an epileptic focus or corpus callostomy. Multiple subpial transections can can also be performed safely in patients whose seizures arise from the eloquent cortex. 当表示, functional mapping of the eloquent cortex is carried out extraoperatively through subdural grids or introperatively under local anesthesia. Investigation into associative 和 sensimotor functions of the brain are also carried out during craniotomy.

癫痫中心

University Hospital's 癫痫中心 is also investigating new options such as cell transplantation to control seizure foci, as well as deep brain stimulation which places neural stimulators deep in the brain to prevent seizures.

Selecting the most appropriate treatment is a team decision 和 the patient 和 patient's family are critical members of this team.

Pacemaker For the Brain: The Vagal Nerve Stimulator

When seizures cannot be controlled by antiepilepsy drugs or the neurosurgical procedures described above, they can often be supressed by another type of nerve stimulator, the vagal nerve stimulator (VNS.) The VNS power source, which is the size of a stopwatch, is implanted in the neck. Electrical stimuli from the VNS are relayed through the vagus nerve in the neck. Electrical stimuli from the VNS are relayed through the vagus nerve in the brain, where these impulses appear to "reset" electrical activities in the brain areas where the seizures start. 这可以防止癫痫发作.
