Treatment

• Endovascular procedures. In an endovascular procedure, your doctor may insert a long, thin tube (catheter) into a blood vessel in your leg or groin and thread it through blood vessels to the dural arteriovenous fistula using X-ray imaging.

  Your doctor inserts the catheter into the blood vessel that leads to the dAVF and releases coils or a glue-like substance to block the abnormal connection in the blood vessels.

• Stereotactic radiosurgery. In stereotactic radiosurgery, your doctor uses precisely focused radiation to block the abnormal connection in the blood vessels.
• Surgery. Your surgeon may perform surgery to disconnect the dAVF.
