Arteriovenous Fistula (AVF)

AVF is an abnormal connection between arteries and veins.

Diagnosis and Symptoms:

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

Treatment:

• Some AVFs require treatment to prevent hemorrhagic stroke.
• Treatment options include endovascular embolization and surgical disconnection. 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.
