SPECIALITY & SERVICES
General Neurosurgery: surgery for the diseases of the brain and spinal cord. This includes :
- Surgery for tumours of the brain and spinal cord.
- Surgery for disorders of the blood vessels of the brain like aneurysms,
- Surgery for all types of strokes including putaminal haematoma,
- Surgery for spinal problems like disc prolapse,
- Neurological problems in children like brain tumours, congenital defects like meningocoel and hydrocephalus
Functional neurosurgery is a new subspecialty which is concerned with the treatment of conditions where the function of the brain and spinal cord is affected but the anatomy (structure) may or may not be normal.
Functional Neurosurgery Includes :
Deep brain stimulation (DBS) for :
- Movement disorders like Parkinsonism, dystonias, essential tremor.
- Some psychiatric problems like depression, OCD, etc
- Chronic pain especially the central post stroke pain.
- Intractable epilepsy
- Intractable alcoholism
- Intractable obesity
- Some types of autism
Intrathecal Pumps :
Intrathecal morphine(ITM) pumps are very useful in:
- Cancer Pains.
- Failed back surgery syndromes.
- Other types of noxious pain.
Intrathecal baclofen (ITB) pumps are good in
- All types of spasticity (including cerebral palsy/ multiple sclerosis, traumatic paraplegics etc).
- Patients in persistent vegetative state.
Spinal cord stimulation (SCS) is very useful in :
- ischaemic heart disease not controlled with medicines, angioplasty or bypass surgery.
- Patients with failed back surgery syndrome.
- Patients with severe pain in the legs due to diabetes (painful diabetic neuropathy).
- Patients with brachial plexus (nerves going to the hands) injury pain.
Sacral nerve stimulation for sphincter disturbances (both bowel and bladder) and including incontinence, retention, constipation etc.
Epilepsy surgery including temporal lobectomy and vagal nerve stimulation.
