title: Left aortic arch and right descending aorta--interruption or severe coarctation of the aortic arch in the newborn.
abstract: Three consecutive neonates (aged 7, 14 and 30 days, body-weight 2980 g, 3000 g and 3400 g respectively) with interruption of the aorta (n = 2) and severe coarctation (n = 1) in the presence of left aortic arch and right descending aorta are reported. Associated lesions were an aortopulmonary window in the first case and an unrestrictive ventricular septal defect in the two others. Intractable heart failure and the complexity of the malformation led to the decision of a staged operation. A prosthetic graft was interposed between the ascending and descending aorta via a right thoracotomy in order to bridge the atretic or hypoplastic segment without using extracorporeal circulation. There was no intraoperative complication. One patient developed a thrombocytopenia within the frame of a sepsis syndrome and died on day 5 after operation, death being caused by a massive bleeding into the left thoracic cavity, although the operation was carried out via a right thoracotomy. Angiography 1 year after operation revealed a good flow through the grafts and no stenosis at the site of the anastomoses. The two surviving infants are clinically well without any medication. The reported operative technique provides an alternative palliative possibility to manage critically ill neonates without any obstacle to later definitive repair.
