GIL-GUEVARA, Enrique; DIAZ, Ramiro; SOSA, Cristian  and  BERMUDEZ, Carlos. Inter-twin placental anastomoses not crossing the dividing membrane: laser photocoagulation of communicating vessels in the twin-to-twin transfusion syndrome. Rev. peru. ginecol. obstet. [online]. 2017, vol.63, n.2, pp.247-252. ISSN 2304-5132.

Twin-to-twin transfusion syndrome (TTTS) is thought to result from an unbalanced exchange of blood through inter-twin vascular anastomoses. Laser photocoagulation of communicating vessels has been used to prevent the development of the syndrome. Some authors have proposed that vessels crossing the membrane are "suspicious" to participate in the development of the syndrome and the laser photocoagulation of these vessels would reverse the syndrome. We present two cases of TTTS where the communicating vessels did not cross the dividing membrane, which were successfully treated with laser.
