Obsessive Comulsive Disorder (OCD)

Gamma Knife Radiosurgery for AVM

Arteriovenous malformations (AVMs) are the leading cause of stroke in young people. Formed during embryonic development, an AVM is a tangle of dilated blood vessels that disrupts normal blood flow in the brain by pooling blood within its dense center or nidus. These vessels may enlarge over time.
The goal of treatment is to reduce this risk of fatal or debilitating hemorrhagic stroke. Twenty years ago, many patients were told their AVM was inoperable because the risks of treatment were considered too high. Today, advanced open skull surgical techniques, radiosurgery and endovascular embolization make the treatment of AVMs safer and highly effective.

Trigeminal Neuralgia : New Treatment Option

Gamma Knife radiosurgery is a method for treating certain problems in the brain without making an incision. Two hundred-one beams of cobalt-60 radiation are focused precisely on a specific region in the brain. In the case of TN, the target area is the trigeminal nerve, just where it leaves the brain. The treatment does not require general anesthesia, and the patient stays in the hospital for less than ten hours.

Hydrocephalus comes from Greek words: hydro means water, cephalus means head. Hydrocephalus is an abnormal accumulation of fluid "Cerebrospinal fluid, or CSF ”within cavities called ventricles inside the brain. This condition may occur at any age. CSF is produced in the ventricles, circulates through the ventricular system in the brain and is absorbed into the bloodstream. CSF is in constant circulation and has many functions. It surrounds the brain and spinal cord and acts as a protective cushion against injury. CSF contains nutrients and proteins that are needed for the nourishment and normal function of the brain. It carries waste products away from surrounding tissues. Hydrocephalus occurs when there is an imbalance between the amount of CSF that is produced and the rate at which it is absorbed. As the CSF builds up, it causes the ventricles to enlarge and the pressure inside the head to increase

Gamma knife treatment

A Gamma knife is a device used to treat brain tumors with a high dose of radiation therapy in one day. The device was invented at the Karolinska Institute in 1967 by Lars Leksell , a Swedish Neurosurgeon.
The gamma knife device contains 201 cobaly-60 sources of approximately 30 curies (1.1 TBq) each, placed in a circular array in a heavilyshielded assembly. The device aims gamma radiation through a target point in the patient's brain. The patient wears a specialized helmet that is surgically fixed to their skull so that the brain tumor remains stationary at target point of the gamma rays. An ablative dose of radiation is thereby sent through the tumor in one treatment session, while surrounding brain tissues are relatively spared.
