Arteriovenous fistulas are abnormal connections between the high-pressure and high-resistance arterial system and the venous system with opposite features. Due to its lower resistance, the blood preferentially flows via the fistula rather than through the capillary bed. The amount of shunt flow depends on its size and proximity to the heart. Due to the increase in circulating volume, progressive dilation develops in the whole vascular system proximal to the shunt. Cardiomegaly and venous distention may return to normal after surgical repair of this vascular abnormality. Two cases are presented of heart failure due to traumatic arteriovenous fistula, one of which was between the right renal artery and inferior vena cava and the other between the left renal artery and renal vein.

UI MeSH Term Description Entries
D008297 Male Males
D012077 Renal Artery A branch of the abdominal aorta which supplies the kidneys, adrenal glands and ureters. Arteries, Renal,Artery, Renal,Renal Arteries
D012082 Renal Veins Short thick veins which return blood from the kidneys to the vena cava. Renal Vein,Vein, Renal,Veins, Renal
D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D001164 Arteriovenous Fistula An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
