Introduction:
Stenosis of pulmonary arteries (PA) 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 PAs. Although, bilateral branch PA stenosis is known, it more commonly affects the left pulmonary artery (LPA). Surgical repair of branch PA stenosis especially the LPA, regardless of the technique employed, carries a significant incidence of recurrence due to the residual ductal tissue and highlights the importance of removing it from the branch PAs which can sometimes compromise their length. This also makes direct tension-free anastomosis difficult to accomplish. We describe a novel way of enlarging the LPA by employing native, autologous pulmonary arterial tissue while excluding all ductal tissue from the anastomotic stoma.
