First-Stage Operation: Blalock-Taussig Shunt (BT)
Because the Ductus Arteriosus
(which is like a natural God-made shunt) normally closes,
the Prostaglandin medication given to keep the Ductus open will
only work for about 2 weeks.
Doctors have to construct a similar
structure called a Shunt which is made from a synthetic material
called Gore-tex. They shape the Gore-tex into a tube like a straw.
They connect one end of that straw to the artery going to the
Right Arm and the other end to the artery going to the Right
Lung (Pulmonary artery).
