Laser Treatment of Twin-twin Transfusion Syndrome

IntroductIonThe treatment of twin-twin transfusion syndrome (TTTS) has evolved through the years and has included expectantmedical management, 1 sectio parva, 2 serial amniocentesis, [3][4][5] and the current treatment using laser photocoagulation of the placental vascular anastomoses.[6][7][8][9][10][11] The rationale for the use of laser photocoagulation in TTTS stems from the fact that:• Twin-twin transfusion syndrome (TTTS) occurs via placental vascular anastomoses, which are responsible for the net unbalanced sharing of blood volume between two (or more) monochorionic fetuses.
