Carotid Artery Stenting
Imaging & Clot RetrievalOur advanced imaging technology allows enhanced views of the brain and blood vessels. These images are used for a variety of minimally invasive approaches to treat neurological conditions. Interventional Neurology Services include:
Biplane 3-D imaging follows the path of blood flow, so the location of a neurological problem can be found quickly and precisely. If a life-threatening blockage is found, a catheter is inserted through a major artery in the leg or arm directly to the stroke site in the brain. Then, a clot-busting drug can be delivered in the case of an ischemic stroke (blockage). And for a hemorrhagic stroke (bleeding in, or around the brain), coils can be placed to stop the bleeding.
MERCI Clot Retriever
For stroke patients who are not candidates for the clot-busting drug t-PA , an interventional neuroradiologist can use biplane angiography to guide the MERCI (Mechanical Embolus Removal in Cerebral Ischemia) Clot Retriever — a tiny corkscrew-shaped device — inside a catheter through the blood vessel to the site of the blockage where it can be used to grab the clot for removal.
The Penumbra System is available for stroke patients who are not candidates for the clot-busting drug t-PA. Interventional neuroradiologists can use biplane angiography to guide the Penumbra to a blood clot in the brain. The system removes the blockage using a microcatheter and unique separator system to restore circulation within the brain.
