Introduction:
Stenosis or disconnection of the left pulmonary artery (LPA) is a well-known anomaly associated with other congenital heart defects. It is presumed to occur due to extension of ductal tissue into the wall of the LPA. Although, bilateral branch pulmonary artery (PA) disconnection is known, it most commonly occurs unilaterally. Non-confluent PAs are supplied by 3 different sources viz. patent ductus arteriosus from aortic arch system, collateral or bronchial arteries from descending aorta or from a variation of persistent truncus arteriosus1. Surgical repair of LPA stenosis / disconnection, regardless of the technique employed, carries a significant incidence of recurrent stenosis due to the presence of ductal tissue and highlights the importance of removing all possible ductal tissue from the LPA which sometimes compromises the length of LPA. This also makes tension-free anastomosis impossible. In order to circumvent these problems, we describe a novel way of restoring the confluence of right pulmonary artery (RPA) with LPA by employing the native, autologous pulmonary arterial tissue itself after removing all ductal tissue to the best extent possible.
