This originates a fluctuant change of colour observed during the fetoscopy between purple and red in the arterial part of the A-V anastomosis that belongs to the small baby. The reason was a marked discrepancy in the growth of both twins Figure 1 and abnormal Dopplers in the small twin.

Therapeutic amniocentesis in twin-twin transfusion syndrome appearing in the second trimester of pregnancy. The explanation to this finding starts in the bad general condition of the small baby whose low central blood pressure, due to lack of oxygenation, produces a low vascular pressure in the placental branches of its umbilical arteries that is not high enough to overcome the pressure of the umbilical vein branches of the big baby at the level of the A-V anastomosis.

Recurrent twin-twin clasiticacion syndrome after selective fetoscopic laser photocoagulation: After the counselling, the patient accepted the surgery and signed the consent forms.
