Stroke Center Innovators Buy Time, Save Brain ~ Clearing the Clog Featuring Gary Duckwiler, MD

On April 20, the CBS show The Doctors featured Dr. Peter Lawrence, chief of vascular surgery, explaining a carotid artery ultrasound test to screen for stroke risk while UCLA technician Vicki Carter performed the noninvasive test on a volunteer. In addition, Dr. Reza Jahan, associate professor of interventional neuroradiology, demonstrated the MERCI Retriever, a device used to mechanically remove a clot from patients suffering an ischemic stroke. 

KCAL-Channel 9 aired March 2, 2009 reports about a new liquid glue used to treat brain aneurysms too giant to be treated by conventional methods. The stories featured Dr. Satoshi Tateshima, assistant professor of interventional neuroradiology, who performed the Ronald Reagan UCLA Medical Centers first case on a patient with a strawberry-sized aneurysm.

On November 28, 2008, NBC Nightly News featured UCLA’s Division of Interventional Neuroradiology’s Dr. Gary Duckwiler discussing new scans that target aneurysms.

The articles below, actual cases treated by physician specialists in interventional neuroradiology at UCLA Medical Center, demonstrate that timely intervention can dramatically reduce brain damage from stroke and aneurysm.

A stroke is an interruption of the blood supply to any part of the brain, in effect a brain attack. Brain cells die causing permanent damage, if blood flow is stopped for longer than a few seconds and the brain cannot get blood and oxygen. Other names for stroke are cerebrovascular disease; CVA; cerebral infarction and cerebral hemorrhage.

There are two types of stroke: Ischemic and hemorrhagic strokes. Ischemic stroke is when a blood vessel carrying blood to the brain is blocked by a blood clot; hemorrhagic stroke is when a blood vessel breaks open, causing blood to leak into the brain.

An aneurysm is an abnormal widening or ballooning of a portion of an artery which is related to weakness in the wall of the blood vessel. If the aneurysm is not treated in time and ruptures, there is a 70% likelihood that the patient will either die or suffer a severe stroke that would prevent them from independent living.

Interventional neuroradiology is the treatment that avoids general anethesia and allows brain monitoring during the procedure. The Clinical Neuroscience Program at UCLA has consistently been ranked in the top 10 in the nation.

We hope that you find these articles, news announcements and illustrations helpful in better understanding stroke and aneurysm, along with descriptions of the procedures and treatments available in interventional neuroradiology at UCLA Medical Center.
