Dural arteriovenous fistula (DAVF) is a rare vascular condition where abnormal connections (fistulas) form between branches of arteries and veins in the dura mater, the brain's covering. The dural arteries deliver high-pressure, oxygen-rich blood to the brain, while the dural veins return deoxygenated, low-pressure blood to the heart. DAVF causes high-pressure arterial blood to flow into veins or sinuses meant for low-pressure blood, which can lead to ruptures, brain hemorrhages, and other neurological issues. Meet Dr. Aditya (Adi) Iyer, a board-certified, fellowship-trained neurosurgeon specializing in vascular diseases of the brain and spine at Pacific Neuroscience Institute®. As one of California’s few dual-trained neurosurgeons, Dr. Iyer offers both minimally invasive open surgical techniques and incisionless catheter-based procedures to treat strokes, aneurysms, AVMs, tumors, and pain.
