The Neurointerventional team at MedStar Georgetown University Hospital treats vascular diseases affecting blood vessels in the head and neck. Each of our interventional neuroradiologists is board certified and has undergone additional fellowship training in their areas of expertise.
Our specialized interventional neuroradiologists diagnose and treat patients with the full range of neurovascular diseases including:
- Stroke (poor blood flow to the brain resulting in cell death)
- Narrowing or hardening of the arteries, including carotid artery stenosis
- Brain aneurysm (enlarged blood vessel)
- Vascular malformations (abnormal clusters of blood vessels), including arteriovenous malformation, cavernous malformation, and vein of Galen malformation.
- Arteriovenous fistula (abnormal connection between an artery and vein)
- Cerebral venous sinus thrombosis (blood clot in the brain’s venous sinuses)
- Moyamoya disease (blocked arteries at the base of the brain)
Diagnosis and Treatment
Our Neurointerventional team uses high-resolution imaging technology, including ultrasound (sounds waves), CT scans (a series of X-ray images), magnetic resonance angiography (a powerful magnetic field and radio waves), and angiograms (an X-ray test) to diagnose complex neurovascular disorders.
Our interventional neuroradiologists work hand-in-hand with the world-class neurologists and neurosurgeons on staff to determine the best treatment strategy for you. These specialists use highly developed and innovative techniques, including endovascular procedures (inside the blood vessels). Procedures include:
- Acute stroke thrombectomy to remove blood clots in the brain through small tubes
- Brain aneurysm treatment that restores normal blood flow and prevents blood vessels from bursting through the use of coils, stents or flow-diverters (such as the pipeline embolization device, which causes a blood clot to slowly form in the aneurysm, further reducing the risk of aneurysm rupture)
- Carotid stenosis treatment through minimally invasive surgery or the use of micro-balloons and stents threaded up to the brain through an artery in the groin to remove fatty deposits in the carotid and restore normal blood flow
- Treatment of abnormal connections between the arteries in the brain using liquid agents to block blood flow (such as Onyx or n-BCA)
