Based on X-rays taken of your blood and lymph vessels (angiography), we can also create computer-generated 3-D models of your blood vessels to guide surgery. Our neurointerventional surgeons use these techniques to treat aneurysms, strokes, blocked arteries and blood clots in your brain and neck. With the assistance of our interventional neuroradiologists, Centura Health provides quick, expert action when you need it the most.
Some of the neurointerventional treatments we offer include:
- Administering tPA (tissue plasminogen activator) directly into a clot: tPA is a blood clot-dissolving drug. If a clot is blocking a large brain artery, a small catheter can be placed within the blockage to deliver tPA directly into the clot, restoring normal blood flow to your brain. In some cases, this can be effective up to six hours after the onset of stroke symptoms.
- Extracting blood clots: Many catheter-based approaches are available to physically extract a blood clot causing a blockage. In some cases, this can be effective up to eight hours after onset of stroke symptoms.
- Intracranial angioplasty: This procedure uses a balloon-tipped catheter to enlarge a narrowed artery in your brain. Angioplasty may be used to open your narrowed brain arteries, helping to prevent a stroke if medication has failed. During an angioplasty, when the balloon and catheter are threaded to the blockage in your brain artery, the balloon is inflated. As it expands, it forces the plaque against your artery wall, opening the vessel and restoring blood flow. In some cases, a stent is inserted to help keep your artery open.
- Patent foramen ovale (PFO) closures: A PFO is a small hole in the heart that can permit blood clots to cross through the heart and into the brain causing a stroke or a transient ischemic attack (TIA), known as a ministroke. With the help of interventional cardiologists, we can close the hole by placing a closure device guided by a catheter to help prevent future strokes.
- Stent insertion: A stent is a small mesh tube, made of either metal or fabric, inserted by a catheter to treat narrow or weak arteries, restoring your blood flow. A stent may be used during treatment for intracranial stenosis (narrowed blood vessels) or a brain aneurysm. This includes carotid stenting, which helps restore blood flow through arteries in your neck that supply blood to your brain. Narrowed arteries in your brain and neck can increase your risk of stroke.
