Transcatheter successful palliation of a newborn with ductal-dependent pulmonary circulation
Ductal stenting a reliable and more physiologic alternative to surgical systemic to pulmonary shunt in neonates. But the lack of stent coverage of the entire ductus (especially in long and tortuous duct) results duct constriction and cyanosis of the patient and causes re-intervention in most cases. It is well known that passing a catheter through the stent is technically very difficult and increases the risk of thrombosis and hemodynamic destabilization when compared with the primary intervention. Therefore stent long must be enough to cover entire ductus. But in some cases a small segment of the duct may be left uncovered and necessitating use of second or third stent. The full-length stenting of the duct without leaving any ductal tissue is important.
