Navigation-guided Brain Surgery

Navigation-guided brain surgery treatment in Yeshwanthpur, Bangalore

The ability to do real-time intra-operative guiding during the brain and spinal surgery is known as neuro-navigation or frameless stereotactic surgery. This skill improves neurosurgical precision and safety, and such technology is quickly becoming the norm in neurosurgical procedures.

Navigation-guided brain surgery is a stereotactic brain surgery to do real-time intra-operative guiding during brain surgery. This gives real-time information about the position of the instruments within the brain and circumvents damage to vital structures.

When would a patient require navigation-guided Brain surgery?

A patient would require navigation-guided brain surgery when there are structural abnormalities in the brain. Doctors might advise a navigation-guided brain surgery in some of the following cases:

  • Congenital brain problems include blood vessel malformation, which occurs when veins and arteries converge in the brain.

  • Internal bleeding in the brain caused by an aneurysm, a weakening and rupture of an artery wall.

  • Brain surgery is used to treat blood clots and bleeding in the brain to avoid major harm to the brain tissue that covers the problem region.

  • Hematomas and other epidural or subdural abnormalities.

  • The accumulation of fluid surrounding the brain causes swelling, persistent headaches, and pressure on the brain.

  • Navigation-guided brain surgery is used to remove brain tumours, especially if they are cancerous.

  • Doctors may recommend brain surgery in some cases of epilepsy caused by a structural defect in the brain or pressure on a nerve.

  • Neuropathic pain can arise when a nerve between the brain and the spine is injured, resulting from a stroke, tumour, or accident, among other things.

  • Navigation-guided brain surgery may assist when the neural impulses needed to manage motor function are too weak or aberrant.

Procedure

Step 1: The radiology technician performs an MRI scan on the patient.

A radiology technician often performs the first critical stage — an MRI scan of the patient's anatomy — the evening or day before the procedure. The MRI captures a crisp image of soft tissue and is more commonly used for brain surgery. To understand more about the procedure visit the Navigation-guided brain surgery hospital in Yeshwanthpur, Bangalore.

Step 2: On the computer, the surgeon creates a 3D model.

The surgeon enters the imaging data from the anatomy scan into the system. The information is used by the surgeon to create a three-dimensional representation of the patient's unique anatomy, which is then shown on a monitor during brain surgery.

Step 3: The surgeon matches the computer model to the patient's anatomy. 

After anaesthesia is administered, the surgeon connects the anatomy to the 3D model of the acquired data. This is called registration. The surgeon starts by using an image-guided pointer or probe to touch a landmark on the patient. The surgeon uses the instrument to tap that location on the screen. The camera in the image-guided surgical system sends a signal from the probe to the computer to record the precise place touched. The surgeon creates a link between the body and the screen picture, point by point, on the patient's body and then on the monitor. The surgeon sees the tooltip's position in the body while he operates by comparing the scan to the actual anatomy during the operation.

Step 4 - During surgery, the surgeon employs an image-guided system. 

During surgery, the tip of the surgical tools will be presented as cross-hairs on the monitor in all three anatomical perspectives. The perspectives change when the surgeon adjusts the devices to illustrate their new position. This also allows the surgeon to see how adjacent the tools are to the vital structures of the brain.
The surgery takes a 2-3 day stay at the hospital. Some patients might face other problems such as weakness,  seizures, or coordination problems that need time as per the doctor's advice. Follow-up visits to discuss postoperative assessments are suggested even after recovery.
