Brain Procedures


Tumor Resection

A brain tumor, whether malignant or benign, is a very serious condition that requires prompt and thorough treatment. Even benign tumors of the brain can grow, albeit slowly, and become life threatening. Primary tumors are those that grow in the brain, while secondary tumors start somewhere else in the body and have now spread or metastasized to the brain. Resection is performed mostly on primary brain tumors, but in some cases resection of secondary tumors are necessary as well.

Brain tumor resection removes part or all of a tumor with the goal of not damaging neurological functions. If complete resection cannot be completed, the tumor can recur and continue growing. Although there are risks involved with brain tumor resection, the dangers of an untreated tumor are worse. Resection may be followed by chemotherapy or radiation, especially if the tumor is not completely removed.

The CyberKnife® Robotic Radiosurgery System is a recent development in the treatment of both benign and malignant tumors. The CyberKnife treatment is the first non-invasive procedure for treating tumors anywhere in the body, including the brain. The system uses imaging software to determine the size, shape and location of the tumor, before delivering radiation specifically to the tumor without significantly affecting the surrounding tissue.

This procedure provides a pain-free and even comfortable setting for patients to receive radiation treatment. Sessions usually last 30-90 minutes and can be repeated if needed. Over 50,000 patients worldwide have been treated under the CyberKnife system.

Gamma Knife

Gamma Knife® surgery offers a non-invasive alternative treatment method to brain tumor patients who do not wish to undergo the traditional, risky open surgery methods. No surgical incision is made during this procedure. Instead, gamma radiation beams are targeted on the lesion, causing it to slowly dissolve. The beams do not harm surrounding tissue but still transmit a high dose of radiation to the treated tumor.

Gamma Knife surgery offers a safer and less expensive treatment alternative that also comes with a painless procedure and shorter recovery time. It can also often reach tumors that were considered inoperable with traditional surgery.

Shunts for Hydrocephalus

Hydrocephalus is a neurological condition that causes an enlargement of brain ventricles due to an accumulation of cerebrospinal fluid.

Hydrocephalus can usually be treated with the placement of a shunt, which is a device that is implanted to drain the cerebrospinal fluid away from the brain and empties in the abdomen where it is absorbed. The shunt can be a traditional fixed pressure or can be programmable to reach the correct pressure for effectiveness. The shunt is implanted during a relatively simple procedure under general anesthesia.
