Unlike veins, which return deoxygenated blood to the heart, arteries transport oxygen-rich blood to the body's tissues. and a veinA vein is a blood vessel that returns blood to the heart. Veins transport deoxygenated blood from the body back to the heart, with the exception of the pulmonary veins, which transport oxygenated blood from the lungs to the heart., leading to a direct, unimpeded blood circulation between these two vessels, bypassing the capillary passage.

The most important facts at a glance

In dogs, an arteriovenousArteriovenous means pertaining to the arteries and veins or refers to the connection or relationship between an artery and a vein. Arteriovenous malformations are examples of pathological connections that can lead to circulatory problems. fistulaA fistula is an unnatural channel or connection between two organs, or between an organ and the body's surface, that can arise from disease, injury, or surgical procedures. In dogs and cats, fistulas can be a cause for concern and may require treatment. can represent a direct connection between an arteryAn artery is a blood vessel that carries blood away from the heart. Unlike veins, which return deoxygenated blood to the heart, arteries transport oxygen-rich blood to the body's tissues. and a veinA vein is a blood vessel that returns blood to the heart. Veins transport deoxygenated blood from the body back to the heart, with the exception of the pulmonary veins, which transport oxygenated blood from the lungs to the heart., where the blood bypasses the capillary network. This leads to altered blood flow dynamics and can strain the heart. Causes include congenitalCongenital means "present from birth" and refers to characteristics or conditions that are already present at birth. This can include genetic disorders, developmental anomalies, or infections transmitted by the mother. anomalies or injuries such as bite wounds. Symptoms may include Swelling, edemaAn edema is a buildup of fluid in the body's tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition., and bluish discoloration of the skin. DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is made by clinical examinations and imaging techniques such as Doppler ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear.

Causes

In a dog’s normal circulatory system, blood flows from the arteries through the capillariesCapillaries are the smallest blood vessels in the body, connecting arteries and veins. They facilitate the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste products between blood and tissues. to the veins.
