Acquired Arteriovenous (AV) Fistula

An acquired arteriovenous fistula is a condition whereby there is an abnormal channel between an artery and a vein. Normally, blood flows from arteries into capillaries and then into veins. When blood flows directly from an artery into a vein, bypassing the capillaries, an acquired arteriovenous fistula is present.

Acquired Arteriovenous Fistula Symptoms

Symptoms of acquired arteriovenous fistula may include:

  • Bulging purplish veins that can be seen through the skin (similar to varicose veins),
  • Decreased blood pressure
  • Fatigue
  • Heart failure
  • Swelling in your legs or arms
