Delayed surgical repair of truncus arteriosus with interrupted aortic arch following bilateral banding of branch pulmonary arteries: a case report

Abstract

Abstract Background Banding of the bilateral branch pulmonary arteries (PA) has evolved as a palliative method to limit the pulmonary blood flow in various complex congenital heart diseases. Although beneficial in small patients and in those with multiple co-morbidities, the duration of pulmonary artery banding along with growth and status of branch pulmonary arteries following de-banding are of concern in these patients. Case presentation We present a case of truncus arteriosus with interrupted aortic arch in whom bilateral PA banding was done in neonatal life. The corrective surgery was delayed by 13 months due to multiple infections and underlying co-morbid conditions. Although the surgery was delayed, the branch pulmonary arteries were of adequate size following the debanding procedure. Conclusion Branch PA augmentation may not always be necessary even in delayed corrective surgery following bilateral PA banding.
