STEREOTACTIC
RADIOSURGERY
- Now, a new advancement in Neurosurgery
The understanding and management
of brain tumours has improved tremendously in the last two decades. Discovery
of cell receptors, crucial enzymes and onco genes has made better understanding
of tumour biology. There have been relentless efforts to improve therapeutic
options for these tumours and thus resulting in improved surgical therapies,
newer drugs and improvements in radiotherapy.
Stereotactic Surgery is a special
field of neurosurgery designed to reach the tumour (focal point) in the brain
in a minimally invasive way through a keyhole through a safe trajectory with
precision. With advances in imaging calculations of X, Y and Z axis,reaching
the target has become much more precise.
Delivery of Radiotherapy to these
tumours has taken a significant leap forward by combining these two techniques.
This has opened a new era of noninvasive neurosurgery called “Stereotactic
Radiosurgery”. Here, in radiation beams are delivered through a stereotactic
method to the tumour (point of interest) without damaging the surrounding brain
or the vital structures. Once the diagnosis of a brain tumour is made with good
imaging with the assistance of software and computers, the whole treatment can
be planned beforehand like virtual reality - the area to be irradiated, the
dose of radiation, the number of beams, directions, size, shape and volume of
beams can be planned. Then the dose is calculated and divided between the areas
and the beams. The whole planning is done and reconfirmed to ensure safety by
the neurosurgeon and the radiotherapist. The patient is then shifted to the
TrueBeam STx machine, which delivers the total dose of radiation through a
rotating arc in just 3-4 minutes with absolute accuracy, speed and safety. The
TrueBeam STx is the world’s most advanced radio therapy machine and technology
commissioned for the first time in Asia-Pacific in Bangalore.
The patient is kept under
observation for a day and discharged. The patient requires a regular follow up
with the neurosurgeon for up to two years.
The indication for this
technology and its clinical applications for the brain and spine disorders are
rapidly expanding. Now It is the standard of treatment and of choice for
vascular malformations of the brain and benign tumours. This is completely
noninvasive, no incisions, no ICU stay and a limited hospital stay of 1-2 days
only. In addition tumours in critical areas and in complex locations like skull
base as well as residual tumours can be e treated effectively. Patients of all
age groups can undergo this procedure. It opens a new option for the elderly
people as well as those with medical complications who are otherwise not fit
for surgery.
BGS Global Hospitals is always
committed to provide state of the art care on par with the best international
standards at affordable prices by adopting such technology .The Global
Hospitals group is further expanding with such installations being made in
Chennai and Mumbai in the near future.
