The main treatment for dural arteriovenous fistulas is still surgery, but there are two types of surgery: the first is interventional, which is commonly known as minimally invasive; the second is open surgery, which is more classic. Nowadays, as technology advances, the interventional approach is more often chosen, that is, the patient lies flat on the surgical bed, a sheath is placed through the root of the thigh, and various guidewires and catheters are used to reach directly around the lesion, so that the corresponding imaging can show what kind of shape the arteriovenous fistula is in, so that specific guidewires, catheters, spring coils and special glue can be placed, so that The fistula can then be closed properly. In some cases, the fistulae are large enough to be embolized with a balloon, and multiple fistulas can be treated together with an adjuvant incision. Therefore, it is important to know what type of condition is present at the time to be able to clarify the treatment plan.
