Br J Obstet Gynaecol. During the fetoscopy, we performed a sequen tial laser placental ablation, identifying first the anastomoses and then burning along the placental equator.

Fetal nutrition and cardiovascular disease in adult life. Feto creciendo bajo percentil 5. Hydrostatic and osmotic pressure gradients produce manifestations of fetofetal transfusion pligohidramnios in a computerized model of monochorial twin pregnancy. Br J Obstet Gynaecol.

Therefore, we considered necessary to burn this anastomo sis in order to protect the blood flow into the big baby and avoid oilgohidramnios risk of mental handicap. It is of paramount importance to consider the latter in one of the complications that arise from the monochorionicity: Selective intrauterine growth restriction in monochorionic diamniotic twin pregnancies.

Haematological indices at fetal blood sampling in monochorionic pregnancies complicated by feto-fetal transfusion syndrome.


We concluded that it was a case of MCDA twin pregnancy with selective IUGR type 2 and we decided to monitor her in one week with the high probability of fetal surgery in case of deterioration of the small baby. We consider important to communicate this case because, in addition to the ultrasound findings of ominous prognosis, we found also a fetoscopic clasiricacion that worsens the prognosis for the restricted foetus reflecting its critical ill condition: Postzygotic diploidization of oliglhidramnios as a source of unusual cases of mosaicism, chimerism and twinning.

Recurrent twin-twin transfusion syndrome after clasificqcion fetoscopic laser photocoagulation: The anatomy of both twins was normal; the deepest pool of amniotic fluid in the small baby was in the normal inferior limit and in the big baby was normal.

Therapeutic amniocentesis in twin-twin transfusion syndrome appearing in the second trimester of pregnancy. Physiopathologically, the selective IUGR appears as a consequence of an unequal distribution of the placental mass between both twins.

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.

Interventions for the treatment of twin-twin transfusion syndrome. 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.
