Stereotactic Biopsy

Stereotactic brain biopsy is a minimally invasive procedure used to obtain brain tissue samples for further diagnosis. Stereotactic neurosurgery involves the mapping of the brain in a three-dimensional coordinate system. With the help of imaging techniques such as MRI, CT scans, and 3D computer workstations, neurosurgeons can target any area of the brain.

Indications of a brain biopsy

If there is any suspicious growth or infection in the brain and your treating neurologist Neurosurgeon is not able to arrive at a diagnosis with non-invasive tests, you may be offered to undergo stereotactic brain tumor biopsy. It can be done for a variety of brain problems including

The procedure of brain biopsy

There are two types of this procedure which are
Frame based stereotactic brain biopsy- which involves fixing a frame in the head before undergoing CT/ MRI and is rarely performed now-a-days
Frameless stereotactic brain biopsy -Always imaging tests such as magnetic resonance imaging (MRI), computed tomography (CT)scans, and three-dimensional computer imaging is one prior to the surgery. These images are then fed into a software which will give virtual mapping of the patient’s brain or scanned area. We call it neuro navigation system. The patient is either put under general anesthesia or local anesthesia. Operative part is cleaned and a small incision is made. Then a small hole that is enough to pass a needle is made. Under the neuro navigation guidance, the target point is chosen and the needle is advanced to the target point to obtain biopsy of the lesion. Stereotactic brain biopsy usually takes ½- 1 hour.

Risks involved with Stereotactic brain biopsy

The risks associated with Stereotactic brain biopsy are minimal. The tissue sample obtained may be non-diagnostic which means the biopsy procedure needs to be repeated. Other risks involved are intracranial hemorrhage, seizure, and infection. 

For the majority of patients, the procedure is safe and useful and can provide some useful information.  

Recovery and follow-ups

After the surgery, bandages will be placed on the incision area which is removed the next day. The patient is required to be under observation overnight for precautionary measures and then free to go home the next day.
Generally, patients do not experience pain although a bit of tenderness around the incision area is normal and they can resume their normal activities from next day after the surgery.
Follow-up management will be based on the results of the stereotactic biopsy brain.

If you have been advised to undergo a brain biopsy, then get a second opinion now get a second opinion from an experienced Neurosurgeon in Dubai for brain biopsy to learn more before undergoing the surgery.
