An embolization is a nonsurgical procedure performed to prevent blood flow to the brain in order to effectively shrink a tumor or block an aneurysm.
The Valley Hospital’s Neurointerventional team is expertly trained in the latest embolization procedures to treat many neurological conditions. Embolization procedures include:
Coil Embolization is a procedure used to treat cerebral aneurysms by blocking blood flow into the aneurysm, which helps to keep the aneurysm from bursting. Coil embolization in a nonsurgical neurointerventional procedure where a catheter is inserted into an artery in the groin, and x-ray-guided to the impacted artery in the brain.
A very small metal coil is then routed up through the catheter and placed in the affected area. The coil is then released, with its springs expanding to ensure it is accurately positioned within the blood vessel. A clot will then form on the coil to prevent the abnormal blood flow beyond the coil’s location.
The Valley Hospital’s team of neurointerventional experts utilizes Onyx embolization for the treatment of DAVF and AVM. For some patients surgery may lead to too much blood loss or brain tissue damage, depending on the severity of their condition. Onyx Liquid Embolization is a procedure by which a liquid agent known as Onyx is delivered through a micro-catheter to the affected area of the in the brain. Hardening of the Onyx begins immediately when it comes into contact with bodily fluids, such as blood. The Onyx embolization material is expected to stop or reduce blood flow in selected blood vessels in the AVM. It is anticipated that embolization of the AVM and surrounding blood vessels may help in correcting or lessening of some or all of your symptoms.
During the procedure, the patient lies down with a special X-ray and monitoring equipment that allows the physician to navigate catheters to the area of the brain requiring the embolization. A tiny catheter is placed into the arterial system and guided to the brain for embolization treatment. The tip of the catheter is placed at site, where Onyx is delivered.
The Valley Hospital’s team of neurointerventional experts utilizes tumor embolization for the treatment of head and neck cancers, intracranial tumors, and extracranial tumors. Tumor embolization is a minimally invasive procedure in which a catheter is navigated into the blood vessels supplying the tumor using x-ray guidance and embolic material is injected to stop blood flow.
