dural Arteriovenous Fistula
Overview: A dural arteriovenous fistula (dAVF) is a type of abnormal connection between an artery and a vein in the dura mater, the outermost layer of the meninges that covers the brain and spinal cord. This abnormal connection can cause a large amount of blood to bypass the capillaries and drain directly into the veins, leading to serious health problems.
Symptoms
Symptoms of a dAVF can vary depending on the location and size of the fistula. Common symptoms include headache, neck pain, hearing loss, ringing in the ears (tinnitus), and vision changes.
Causes
The cause of dAVF is not well understood, but it may be related to genetic factors, trauma, or other underlying medical conditions.
