Ohio State Neurosurgeon Uses Onyx to Help Slow Bleeding in the Brain

A neurosurgeon at the Ohio State University Medical Center has moved from using a crazy glue – like substance to something more like lava to prevent ruptures and strokes in patients with brain abnormalities.

Dr. Louis Caragine is director of vascular and endovascular neurosurgery. He says hemorrhaging in the brain which causes stroke is one of the leading causes of disability in the U.S. And it commonly hits people in the prime of their lives.

He says one brain abnormality is a tangle of vessels, called an artero-venous malformation or AVM. It is responsible for strokes, and it responds to the use of the black, lava-like substance known as Onyx.

Caragine uses a catheter to feed the Onyx through an artery into the brain into the tangled vessels. If the procedure is successful, it can slow the bleeding and make surgery possible. Or, it might eliminate the need for brain surgery.
