Arteriovenous Malformations (AVMs)

AVMs are an abnormal tangle of blood vessels disrupting the normal connections between arteries and veins.

Diagnosis and Symptoms:

• AVMs may rupture and cause brain bleeding (see hemorrhagic stroke).
• Symptoms can include headaches and tinnitus (whooshing sounds).
• Diagnosis is done through blood vessel imaging such as MRA, CTA, and diagnostic cerebral angiography.

Treatment:

• Some AVMs require treatment to prevent hemorrhagic stroke.
• Treatment modalities include endovascular embolization (catheter-based), surgical disconnection, and radiotherapy. Your physician will discuss treatment options.
• Lifestyle Modifications: Maintaining normal blood pressure, avoiding smoking, practicing good sleep hygiene, following a healthy diet, and regular exercise can reduce the risk of bleeding.
