What is stereotactic radiosurgery (SRS)?

Stereotactic radiosurgery is a non-surgical method of treating tumors in the brain and spine. The technique requires a three-dimensional outline of the tumor to be generated using MRI and CT scans. Then, a highly concentrated dose of radiation is delivered to the exact affected area. The accuracy of the radiation spares healthy brain tissue from exposure, resulting in fewer side effects than seen in traditional radiation therapies.

Dr. Vasudevan, brain and spine surgeon in St. Louis, partners with an expert team to implement SRS treatment.

What are the benefits of SRS?

The stereotactic radiosurgery method is faster than other types of radiation therapy, with a majority of Dr. Vasudevan’s SRS patients being treated on an outpatient basis over a single day.

SRS is a precise procedure resulting in healthy brain tissue having minimal exposure to radiation. The accuracy offered by SRS also allows Dr. Vasudevan, brain and spine surgeon in St. Louis, access to the deepest recesses of the brain which were not previously accessible via conventional surgery.

Avoiding surgical risks is an additional benefit of SRS. Risks like hemorrhage, anesthesia complications, and wound infections are all avoided through stereotactic radiosurgery.

Treating tumors with SRS

SRS is commonly suggested for patients at our practice whose brain or spine tumors may not require or may not be candidates for surgical treatment. The following tumors may benefit from stereotactic radiosurgery treatment:

  • Meningiomas

  • Pituitary tumors

  • Metastatic tumors

  • Acoustic neuromas

There are additional uses for radiosurgery for patients in St. Louis beyond tumor removal, such as trigeminal neuralgia.
