Spontaneous closure of ductus arteriosus in interrupted aortic arch with ventricular septal defect.
A 2-month-old boy diagnosed with interrupted aortic arch type B was treated with a two-stage procedure. His ductus arteriosus had closed spontaneously. Collaterals via both vertebral arteries developed. A 15-mm stenotic segment existed between the left subclavian artery and the descending aorta. The direct anastomosis between the common carotid artery and the descending aorta was performed as a first palliation at the age of 3 months. The left subclavian artery was reconstructed by end-to-side anastomosis to the descending aorta. The postoperative course was uneventful. The closure of ventricular septal defect and pulmonary artery debanding were performed as a second operation 4 months after the first palliation. The patient is alive and well 7 months after the second operation.
