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.

Endoscopic laser surgery versus serial amnioreduction for severe twin-to-twin transfusion syndrome. Therefore, we considered necessary to burn this anastomo sis in order to protect the blood flow into the big baby and avoid any risk of mental handicap.

Colour Doppler energy insonation of placental vasculature in monochorionic twins: A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in size between the foetuses. Long-term neurodevelopmental outcome after intrauterine laser treatment for severe twin-twin transfusion syndrome.

Placental angioarchitecture in monochorionic twin pregnancies: The sIUGR can be diagnosed since the very first trimester by identifying in the ultrasound a marked discrepancy between the CRLs like in our case. Fetal and neonatal hypertension in twin-twin transfusion syndrome: The natural history of monochorionic twins and the role of prenatal ultrasound scan.

It is of paramount importance to consider the latter in one of the complications that arise from the monochorionicity: Doppler detection of arterio-arterial anastomoses in monochorionic twins: Cochrane Database Syst Rev.


Among these complications we have the twinto-twin transfusion syndrome, the selective fetal growth restriction, the twin anaemia polycythemia sequence, the twin reversed arterial perfusion sequence and the monoamniotic pregnancy 1. Am J Obstet Gynecol. We consider important to communicate this case because, in addition to the ultrasound findings of ominous prognosis, we found also a fetoscopic sign that worsens the prognosis for the restricted foetus reflecting its critical ill condition: Among the identified anastomoses, we clearly found one arterio-venous anastomosis from the restricted fetus towards the normal one that showed a fluctuant colour between red and purple which is unusual in this type of anastomoses unidirectionals.

Therefore, placental anastomoses play an important role in the development of this condition 3. clasifixacion

Hydrostatic and osmotic pressure gradients produce manifestations of fetofetal transfusion syndrome in a computerized model of monochorial twin pregnancy. One important point to consider is that since both babies are connected to each other through the placental anastomoses, the wellbeing of one of them critically depends on the wellbeing of the other. Her neurological development has been adequate 6 months of age.


Precoz antes de las 28 semanas. Fetal assessment in low risk pregnancy. The ultrasound findings that worsen the prognosis of a pregnancy complicated with sIUGR are the discrepancy in the EFW between the twins, Doppler of the umbilical artery and ductus venosus of the restricted foetus along with oligohydramnios, gestational age at the moment of the surgery and cervical length 7.

We report the case of a MCDA twin pregnancy complicated with selective IUGR, managed with fetoscopic surgery, in which we describe ultrasound criteria of severity and a fetoscopic sign of bad prognosis for the small twin: Abundant vascular anastomoses in monoamniotic versus diamniotic monochorionic placentas.
