At the Swedish Neurovascular Center, our experts bring together a unique blend of cutting-edge treatments for the most complex neurovascular conditions.
Our Expert Team
The Swedish Neurovascular Center physicians are at the forefront of clinical research, working to progress innovative procedures and treatment options. Our team is well-respected throughout the nation and have served as leaders in national industry societies.
Our neurovascular surgeons and interventional radiologists work together, holding weekly case conferences to examine and thoroughly discuss each case. The physicians then work with each patient to create a treatment plan. Our neurovascular care coordinator then guides the patient throughout the process, helping to coordinate care throughout hospitalization and make the transition from inpatient care to outpatient services.
Our Advanced Facility
Our state-of-the-art 3-D angiography suite supports our interventional Neuroradiologists who are available 365/24/7. Swedish also is the only medical center in the region with a 3T MRI with functional mapping capability. In addition, our facility provides biplane angiography, an advanced, minimally invasive technology used to diagnose and treat neurological conditions including stroke, brain aneurysms, brain and neck tumors, intracranial hemorrhages and arteriovenous malformations (AVMs).
Areas of Expertise
Our team treats a full-range of neurovascular conditions, including:
- Ischemic Stroke
- Hemorrhagic Stroke
- Cerebral Aneurysms
- Carotid Disease, Stenosis
- Arterial venous malformations (AVMs)
- Other Conditions
A cerebral aneurysm occurs when the wall of a blood vessel in the brain becomes weakened and enlarges. This puts pressure on the nerves and brain tissue. If the blood vessel wall becomes so weak it bursts, a hemorrhagic stroke, brain damage, coma or death may occur.
Symptoms of Cerebral Aneurysms
The Swedish Neurovascular Center provides treatment for both unruptured and ruptured aneurysms. A large aneurysm that grows steadily might procedure symptoms such as:
- Single-side face paralysis
- Dilated pupil in the eye
- Vision Changes
- Numbness or weakness
- Pain above and behind the eye
Ruptured aneurysm symptoms include:
- A sudden and extremely significant headache
- Double vision
- Nausea or vomiting
- Stiffened neck
- Loss of consciousness
- Cardiac arrest
Diagnosing Cerebral Aneurysms
Cerebral aneurysms can be discovered with imaging such as computed tomography (CT), magnetic resonance imaging (MRI), cerebral angiography or cerebrospinal fluid (CSF) analysis.
Cerebral Aneurysms Treatments at The Swedish Neurovascular Center
Cerebral aneurysms can be treated with endovascular (minimally invasive) options or open surgical procedures. Our team of experts are skilled in the full range of treatments available. Surgery may include microvascular clipping (which cuts off blood flow to the aneurysm) or placement of a shunt (redirecting fluid to elsewhere in the body). Endovascular treatments are less invasive and are used whenever possible. They may include platinum coil embolization and flow diversion devices. Medication may also be used in conjunction with the treatment plan.
Carotid Artery Disease (Stenosis)
The carotid arteries are the blood vessels that bring blood to the brain and head. When one of these arteries becomes narrowed due to a buildup of plaque (atherosclerosis), carotid artery disease (also called carotid artery stenosis) occurs.
This disease can progress without symptoms but puts patients at a much increased risk for a stroke. A ‘warning sign’ may include a transient ischemic attack (TIA), which is a mini-stroke. Symptoms of TIA are the same as a stroke, and as such, immediate medical treatment is necessary.
Symptoms of Stroke
- Trouble speaking and understanding
- Paralysis or numbness in face, arm, leg
- Blurred or double vision
- Trouble walking
If you think someone is suffering from a stroke, think FAST and do the following:
- Face. Ask the person to smile. Does one side of the face droop?
- Arms. Ask the person to raise both arms. Does one arm drift downward? Or is one arm unable to rise up?
- Speech. Ask the person to repeat a simple phrase. Is his or her speech slurred or strange?
- Time. If you observe any of these signs, call 911 immediately.
Treatment of Carotid Artery Disease at The Swedish Neurovascular Center
The Swedish Neurovascular Center offers the latest treatments for carotid artery disease. This includes artery stenting, in which a self-expanding mesh tube is placed within the artery at the site of the narrowing to allow for better blood flow. These stents remain permanently in place. For patients who may not be eligible for stenting, traditional open surgery to remove the plaque and affected portion of the artery may be indicated.
Arterial Venous Malformations (AVMs)
Arterial venous malformation is a rare condition in which the blood vessels of the brain or spine are abnormally tangled. This can disrupt normal blood flow and may also lead to bleeding in the brain (hemorrhage).
Symptoms of AVM
Many people with AVMs do not experience any symptoms and are treated only after discovering the condition with an imaging scan for another brain issue or if the blood vessels rupture and cause bleeding in the brain.
Some patients experience seizure, headache, muscle weakness or numbness, confusion or inability to understand others, difficult speaking and vision loss.
Treatment of Arterial Venous Malformations (AVMs) at The Swedish Neurovascular Center
The Swedish Neurovacular Team reviews each patient’s case to determine the best course of treatment for the individual. Embolization is typically recommended. This minimally invasive procedure is used to block blood vessels that are a part of the abnormality. Other options may include radiation therapy and surgical removal.
Other Neurovascular Conditions
The Swedish Neurovascular Center team is highly experienced in treating all forms of neurovascular diseases and conditions, including the more rare conditions, such as cavernomas and Moya Moya.
Cavernomas (also called cavernous angiomas or cavernous malformations) are abnormal clusters of vessels filled with blood. Unlike AVMs, these malformations have little blood flow. However, since the walls are weak, blood can leak out and cause seizure, stroke symptoms and headaches. Our team thoughtfully reviews each case taking into account the amount of cavernomas, the location of them, the presence of other conditions and the amount of bleeding. Treatment is based upon these factors and may include mediations, observation or surgery.
Moyamoya is a rare, progressive vascular disorder. The name means “puff of smoke” in Japanese and is used to describe the look of the blood vessels that form to compensate for a blocked area at the base of the brain (basal ganglia). Symptoms of Moyamoya include headache, seizures, weakness and difficulty speaking or understanding others. While this condition is not curable, surgical treatment can be used to provide alternative blood flow to the brain. This helps to reduce the risk of stroke or other complications.
