High Tech “Glue” for Aneurysms

Until recently, endovascular specialists like Dr. Lopes at Rush University Medical Center, treated aneurysms exclusively with coils that were used to fill the aneurismal sac. The coils are designed to limit blood flow into the weakened blood vessels of the aneurysm and reduce the risk of rupture. Endovascular neurosurgeons, like Dr. Lopes, continue to investigate alternatives to the coiling method as the science and experience with treating aneurysms using a minimally-invasive approach expands.

In 2007, Dr. Lopes was among a select group of endovascular specialists that introduced a new liquid embolic material called Onyx HD as an alternative to fusion. It is the first “glue-like” substance to be available in the United States for the treatment of intracranial aneurysms. This new technique using Onyx HD allows for more complete aneurysm filling when compared to coiling and therefore a lower rate of recurrence for these challenging aneurysms.

The Onyx HD procedure is performed very similar to a coiling procedure. However, instead of placing coils in the aneurysm, the liquid Onyx HD is used. The Onyx HD is carefully injected directly into the aneurysm through a small, thin micro-catheter while the bottom or base of the aneurysm is temporarily sealed with a separate balloon tipped catheter. The entire procedure takes about three hours and patients usually stay in the hospital one or two days. Recovery time is very short and many people return to work within in a week or two.

Dr. Lopes at Rush University Medical Center is one of a select group of individuals in the Midwest with experiencing using this new technique to treat unruptured aneurysms. Please call 312-563-4000 or email Dr. Lopes at info@ChicagoStrokeMD.com for more information.
