Case Reports[The diagnosis by a Doppler color echocardiographic method of an aortocaval fistula following the rupture of an aortic aneurysm into the inferior vena cava].
We describe a clinical case presenting 2 rare features. The first was a spontaneous aortocaval fistula which had developed from rupture of an atherosclerotic aortic aneurysm into the inferior vena cava. ⋯ In fact, using an echo-color Doppler flow imaging (HP 77020A ultrasound system) with a 2.5 MHz echocardiographic probe abdominal examination showed an aneurysm of the descending aorta that communicated to a dilated inferior vena cava. Furthermore, flow study with color Doppler showed a continuous turbulent, mixed (arterial and venous) blood flow into the inferior vena cava.
