Neuroendovascular Program

Neuroendovascular therapy is a subspecialty within the fields of interventional radiology and neurosurgery that treats complex conditions of the brain such as stroke, aneurysm and arteriovenous malformations (AVMs). With the availability of this advanced capability in Portland, patients have 24/7 access to time sensitive treatments. Our team of fellowship-trained neuroendovascular specialists provides responsive, sophisticated care that consistently saves lives and dramatically minimizes disability.

Quality Outcomes

Carotid Endarterectomy

Carotid endarterectomy is a surgery to remove fatty deposits (plaque) that are narrowing the arteries in your neck. These are called the carotid arteries. They supply blood and oxygen to the front part of our brain. If plaque and other fatty materials block an artery, it slows or blocks the blood flow, and you could have a stroke.

Carotid Stenting

Our vascular specialists use a procedure called angioplasty to widen the carotid arteries and restore blood flow to the brain. A thin tube with a deflated balloon on the end is threaded through a blood vessel in your neck to the narrowed or blocked carotid artery. Once in place, the balloon is inflated to push the plaque outward against the wall of the artery. A stent (a small mesh tube) is then put in the artery to support the inner artery wall. The stent also helps prevent the artery from becoming narrowed our blocked again.

Brandon's Story

When Brandon suffered a stroke following a major automobile accident in Presque Isle, he was transported to MMC. The neurosurgical team performed a mechanical thrombectomy to remove a clot and saved Brandon’s life, enabling him to make a remarkable recovery.
