Stereotactic Brain Biopsy is a surgical procedure. The aim is to obtain a small specimen from the diseased part of the brain to make the diagnosis. If there is suspicion of a tumor, the biopsy procedure aims to identify whether it is benign or malignant. The procedure is performed to understand if the disease is originating from the brain or if it has spread to brain from another part of the body. This information helps selecting the suitable treatment method.
How Is Biopsy Performed?
The patients are asked to stay hungry on the day of biopsy. A device, called stereotactic frame, is attached to the patient’s head under local anesthesia. Next, MRI is scanned. The images are reviewed on the computer and the region to be biopsied is determined very precisely. Then, the patient is transferred to the operating theatre. Here, drugs required for the procedure are administered by the anesthesiologist. The biopsy procedure is performed under local anesthesia.
Pathologist either specifies the diagnosis or reports that the diagnosis can be made within a few days after necessary dye-based examinations are done. Generally, there are two options.
The biopsy needle is removed and a small suture is placed on the skin at the end of the procedure. The frame is detached and the patient is transferred to the room. Computerized tomography is scanned to check the condition. Generally, the time spent at the operating theatre is 45 minutes.
After The Biopsy
Experience of the physician is critical for stereotactic biopsy. Prof. Selçuk Paker, M.D., has carried out this procedure for more than 700 patients.
