Abstract
In neonates, the management of ductus dependent pulmonary circulation is challenging.
There have been three palliative therapies for this lesion: the modified Blalock-Taussig
shunt, ductal stenting and prostaglandin E infusions, for maintaining the ductal patency
before definite operations. Debates remain with regard to the indications and disadvantages
of three palliative therapies. The aim of this article is to give a brief review of
these three palliative therapies.
