Study Finds that Surgical Treatment of Arteriovenous Fistulas Is Safe and Effective
A spinal arteriovenous fistula is an abnormal tangle of blood vessels that develops near the base of a spinal nerve. These fistulas cause spinal tissue to be starved of normal amounts of oxygen, and therefore, cells begin to die. The fistula may rupture and cause a spinal hemorrhage. Symptoms vary greatly, but may include tingling, numbness or progressive weakness in lower extremities, burning pain and bladder problems. Spinal arteriovenous fistulas occur most often in men older than 40.
