Abstract
Two patients (aged 10 and 16 months) underwent right pneumonectomy: onefor an oesophageal bronchus, the other for a hypoplastic right lung withsequestration. Both patients subsequently developed severe stridor. Theheart rotated to the right and the aortic arch compressed the trachea. Thisunusual vascular compression was treated by a bypass graft between theascending and descending aorta and division of the aortic arch between theleft carotid and left subclavian artery at the age of 5 years and 4 months,and 20 months respectively. The postoperative recovery was uneventful inthe first patient. The second patient required 7 weeks of ventilatorysupport. Both patients are well (14 and 7 years after surgery). Cardiaccatheterisation and angiography in the first patient and Dopplerechocardiography in the second demonstrated unrestricted flow through thegraft into the descending aorta. Pulmonary function studies showed arestrictive defect with some obstruction in both children. Despite thisfinding, both patients enjoy a normal life with some sporting activities.The long-term results suggest the effectiveness of this procedure in thetreatment of this rare but severe complication of pneumonectomy ininfancy.
