Twin to Twin Transfusion Syndrome (TTTS) is a rare but life-threatening condition that affects 10 to 15 percent of identical twins that share a placenta (monochorionic twins). TTTS can also occur in triplet or higher order pregnancies with monochorionic twins.

TTTS can have serious consequences to the babies so you will need to be monitored very closely by your doctors.

This video explains TTTS and the treatment option called laser therapy.
