case_images: Cardiac catheterization prior to surgical repair showed bilateral confluent adequate size pulmonary arteries filling through multiple large APCs from the descending thoracic aorta (DTA) [Figure 1] and the child underwent gel foam/coil embolization of multiple APCs.
case_images: Postoperative digital substraction angiography (DSA) with 4F Cobra catheter in the ostium of APC shows persistent filling of bilateral pulmonary arteries from this vessel
