Abstract:
We report a child with Truncus Arteriosus who developed bilateral proximal branch pulmonary stenosis, following total surgical repair of her condition with construction of the right ventricular outflow tract utilizing a Contegra conduit (Medtronic Inc., Minneapolis, Minn.). The obstruction was relieved completely utilizing bilateral percutaneous stent implantation. To the best of our knowledge, this is the first reported case of bilateral stent implantation to relieve branch pulmonary artery stenosis in Lebanon. This technique could be applied to similar cases of obstruction in the pulmonary tree.
