Aneurysm, Cerebrovascular Disease and Stroke Prevention

Find a neurologist
Cerebrovascular disease, which includes aneurysms and other abnormal vein structures, can affect blood flow to the brain, increasing your stroke risk. Nuvance Health™ treats these complex conditions using leading techniques, some of which are not widely available.

You receive personalized care that lowers your stroke risk and preserves your well-being. The team includes experienced neurologists specializing in stroke care and prevention. For eligible patients, treatment may include minimally invasive procedures to implant devices that repair weakened blood vessels.

Cerebrovascular Diseases We Treat

Conditions we treat include:

  • Arteriovenous malformation (AVM): A rare condition typically present at birth in which blood vessels become tangled and affect blood flow to the brain.
  • Brain (cerebral) aneurysm: A weak section in a blood vessel wall that balloons outward and can burst (rupture), causing a hemorrhagic stroke.
  • Subdural hematoma: Bleeding as a result of a head injury that occurs between the brain’s surface and protective outer covering.

Stroke Prevention Services at Nuvance Health: Why Choose Us? 

Nuvance Health is among the few cerebrovascular disease program serving New York’s Hudson Valley and Western Connecticut. We deliver comprehensive care, including testing, treatments and ongoing monitoring, when necessary. Highlights of our program include:

  • Skilled team
    You receive care from doctors specializing in cerebrovascular disease. Fellowship-trained endovascular specialists deliver therapies using small incisions, advanced technologies. The team also includes nationally recognized neurosurgeons with years of cerebrovascular disease experience. 
  • Advanced therapies
    You have access to advanced endovascular treatment technologies that are not widely available. We use the innovative implantable devices that offer better protection against aneurysm rupture than traditional methods. We also use implantable devices that repair aneurysms by strengthening blood vessels.
  • Appropriate care
    Some cerebrovascular conditions progress slowly, posing little threat to the brain’s blood supply. These conditions do not require immediate treatment. Cerebrovascular specialists provide regular monitoring to detect the early signs of changes that may require treatment.

Who Is Cerebrovascular Disease Care For?

Early-stage cerebrovascular diseases typically do not cause symptoms, making it difficult to know when to seek help.


You may benefit from cerebrovascular disease care if you:

  • Show signs of cerebrovascular disease: Doctors typically uncover these problems in imaging scans for other conditions, like head injuries.
  • Are a stroke survivor: If you’ve experienced a stroke, you face a higher risk of new cerebrovascular problems after treatment.

If you or a loved one experiences stroke-like symptoms, including sudden numbness and difficulty talking or moving, dial 911. This is the quickest way to access emergency stroke care.

Cerebrovascular Disease Evaluation and Treatment

Your care starts with computed tomography (CT) angiography. This sophisticated imaging study produces 3D images enabling us to assess the fine details of the brain’s blood vessels. For complex cases, endovascular specialists and neurosurgeons work together to determine the best treatment for your needs.


We offer a broad range of cerebrovascular disease treatments, including:

  • AVM repair: We use surgical or endovascular techniques to repair abnormal vein structures, so they are less likely to rupture. Care may include inserting coils or a glue-like substance to seal the vessel. Your body naturally routes blood around these areas, delivering it to where it’s needed.
  • Embolization for uncontrollable nosebleeds: Frequent nosebleeds do not raise your stroke risk, but can be bothersome. If the bleeding doesn’t stop easily, you may need a procedure to disrupt blood flow to the vessel causing it. We thread a catheter from a small incision in your groin to the blood vessel and insert glue-like particles.
  • Middle meningeal artery embolization: This option stops brain bleeds due to subdural hematoma. We use endovascular techniques to access the bleeding blood vessel and apply tiny beads to stop it. This option provides lasting protection against continued or future bleeds in the same area.
  • The Pipeline™ Flex flow diversion device: Using endovascular techniques, we insert a long, braided device that reinforces blood vessel walls near an aneurysm. The device diverts blood flow through the vein instead of into the aneurysm. Over time, the blood vessel walls regain their natural shape, lowering the risk of future problems.
  • Woven EndoBridge® (WEB) device: We use endovascular techniques to implant a tiny mesh device that expands and directs blood away from the aneurysm. The device creates a better seal than traditional devices (coils) that sometimes leave room for blood to seep in.
