Percutaneous closure of congenital aortocaval fistula with a coexisting secundum atrial septal defect

Abstract

Congenital aortocaval fistula is a very rare anomaly. Clinically, it resembles conditions that cause left-to-right shunt of blood. We report a case of such anomaly in combination with a secundum atrial septal defect in a 13-month-old girl who presented with failure to thrive and exertional respiratory symptoms. The aortocaval fistula was occluded percutaneously using an Amplatzer® Duct Occluder.

Congenital aortocaval fistula between right aortic sinus of Valsalva and superior vena cava: A rare case report

“…An arteriovenous fistula describes an abnormal connection between an artery and vein, which results blood from a high‐resistance arterial system is shunted to a low‐resistance venous system . Aortocaval fistula is a rare cause of left to right shunt . The prevalence of congenital form is unclear.…”

“…3 Aortocaval fistula is a rare cause of left to right shunt. 4 The prevalence of congenital form is unclear. Majority of these fistula drain into RA, RV, and PA (pulmonary artery).…”

Transcaval TAVR—What the Radiologist Needs to Know

“…It contains polyester fabric inserts which help close the fistula and provide a scaffold for the growth of tissue. The offlabel use of occluder devices to close congenital and acquired aortocaval fistulas has been reported previously [9][10][11].…”

Endovascular repair of delayed traumatic aortocaval fistula

“…Less commonly, ACFs are caused by trauma or surgical injury or are the result of endovascular procedures. Rarely, ACF due to a congenital anomaly can be manifested in infancy 9 . Davis et al 10 reported an 11% incidence of iatrogenic ACF in a case series of 18 patients during 20 years.…”
