| Popis: | Increased filling of aortopulmonary collateral arteries occurs when the descending aorta is obstructed distal to their origin. We used this fact to develop a simple, safe technique for improving angiographic visualization of these arteries. The abdominal aorta is manually compressed against the spine during injection of contrast medium. A slight reflex bradycardia resulted, which probably also enhanced filling of the collateral arteries. In eight infants and children with either pulmonary atresia and a ventricular septal defect or truncus arteriosus communis, excellent visualization was consistently achieved without complication. |
