A Dural Arteriovenous Fistula (dAVF) is a rare but potentially serious condition involving an abnormal connection between an artery and a vein within the dura mater, the protective covering of the brain and spinal cord. This direct connection bypasses the normal capillary system, causing high-pressure arterial blood to flow directly into veins, which can lead to increased pressure, vessel damage, and even life-threatening brain hemorrhages.
dAVFs can occur in anyone but are most commonly diagnosed in adults between the ages of 40 and 60. They may develop spontaneously or be triggered by:
This condition affects fewer than 1 in 100,000 people annually, making early diagnosis and expert care essential.
Symptoms vary depending on the location and severity of the fistula. Some patients may have no symptoms, while others may experience:
If a dAVF ruptures, it can cause a hemorrhagic stroke, which is a medical emergency.
Our neurosurgical team offers state-of-the-art treatment options tailored to the type and severity of the dAVF:
A minimally invasive procedure where a catheter is guided through blood vessels to the fistula. Coils or glue-like materials are used to block the abnormal connection.
In cases where embolization is not effective, open surgery may be performed to disconnect or remove the fistula.
Focused radiation is used to close off the abnormal vessels over time—ideal for smaller or less accessible fistulas.
For low-risk, asymptomatic dAVFs, regular monitoring with imaging may be recommended.
Our board-certified neurosurgeons specialize in complex cerebrovascular conditions like dAVF. We use advanced imaging, minimally invasive techniques, and a multidisciplinary approach to ensure the best possible outcomes for our patients.
