Arteriovenous is a term used to describe a connection or pathway between an artery and a vein. There are several synonymous terms that can be used instead of arteriovenous, including arteriovenous fistula, arteriovenous malformation, arteriovenous graft, and arteriovenous shunt. These terms are used to describe different aspects of the same condition, such as a connection between an artery and vein that is abnormal or created surgically for dialysis treatment. Arteriovenous anomalies can occur in different parts of the body, including the brain, lungs, and liver, and can present various health risks. Synonyms for arteriovenous can be helpful in medical communication to describe this condition accurately.
