Dural arteriovenous fistulas (DAVFs) are like tiny highways where blood flows too quickly from arteries to veins in the tough covering of the brain called the dura. This unusual connection can cause problems because it disrupts normal blood flow. DAVFs might not cause any symptoms at first, but they can lead to serious issues like headaches, vision problems, or even strokes if left untreated. Doctors use special tests like MRIs or angiograms to find DAVFs. Treatments like closing off the abnormal blood vessels can help prevent complications and restore normal blood flow, improving the patient's condition.
