The window ductus: Circulatory arrest as an option for surgical repair

The window ductus represents a very rare anatomical anomaly. Only a few cases of successful surgical repair have been reported. We present a 12 year old boy in whom window ductus was diagnosed and successfully operated. The operation included closure of the large (2.5 cm×0.5 cm) connection between the main pulmonary artery and the aortic arch using cardiopulmonary bypass and hypothermia with circulatory arrest.
