A simple technique of reflux aortography for demonstration of adominal aortic aneurysms is described. The technique combines the use of the Valsalva maneuver with retrograde pressure injection of contrast material through a unilateral percutaneous common femoral artery needle. It is particularly useful in the high-risk group of patients with abdominal aortic aneurysms, many of whom have extremely arteriosclerotic and tortuous iliac arteries which make passage of wire guides and catheters difficult and hazardous.
