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.
