[A catheter for imaging the persistent ductus arteriosus].
Nonsurgical techniques for patent ductus closure require precise knowledge of ductus diameter, length and shape. Angiographic visualization, especially in adults, may be difficult, due to the high flow and overlap of the aorta or the pulmonary artery. We have developed a new catheter for visualizing a patent ductus without intraarterial injection of contrast dye. A smooth latex balloon is mounted near the tip of this catheter and when it is filled with dye, the balloon fits the contours of the ductus. Ductus diameter may be established by measuring the diameter of the balloon. Furthermore, the hemodynamic consequences of ductus closure may be observed with the balloon occluding the ductus.
