Endovascular Neurosurgery

It is a type of brain surgery done from inside the blood vessels. Catheters are navigated through the blood vessels and micro instruments are passed through them to do the procedure. It is done through a small incision in the skin over the groin to access the main blood vessel in the thigh and catheters are navigated into the brain under X-ray control. Since the incision is for needle entry it is called Pinhole surgery. The procedure is entirely done under X-ray control in a special room called cath lab and utilizing a technique called digital subtraction angiography. Here the skull bones are subtracted and brain vasculature is well seen.

  •   Obstructive hydrocephalus, occurs when the flow of CSF is blocked or obstructed.
  •   A small hole is made in the skull.g
  •   An endoscope using small camera is guided into the brain through this hole to identify ventricular surface.
  •   When ventricular surface is identified, a tiny perforation is made in the floor of third ventricle.
  •   This will create a pathway for CSF and allow it to flow from the blocked ventricles into the cavities in the brain.
  •   ETV restores the flow of cerebrospinal fluid in the brain.
  •   After all the steps are performed, the wound will be closed with thorough care.
The main advantages of ETV are;
  •   It does not leave or implant any mechanical device inside your brain
  •   Risk of infection is comparatively less than shunt surgery.
  •   Usually ETV is not performed in patients below 2 years old as its success rate in infants is less.

At the same time, this surgery may not be effective in all other patients with obstructive hydrocephalus.

Complications of ETV
  •   Inability of brain to re-absorb CSF
  •   Hole closure
  •   Chance of infection, but lesser
  •   Bleeding inside your brain
  •   Vision problems
  •   Weakness down one side of the body
