ICD-Code I77.0: Arteriovenous fistula, acquired
You have an abnormal connection between an artery and a vein.
Arteries are blood vessels that transport blood away from the heart. They supply all the tissue in the body with oxygen-rich blood. Veins are blood vessels that transport the blood back to the heart.
For instance, a connection between an artery and a vein can develop after surgery or an injury. With this type of connection, blood flows directly from the artery into the vein. This can cause affected blood vessels to widen. It is also possible that the affected area of the body does not receive enough oxygen-rich blood.

- G: Confirmed diagnosis
- V: Tentative diagnosis
- Z: Condition after
