Polyhydramnios related to polyuria resulting from a state of constant hypervolemia is observed in the recipient twin, finally evolving into congestive heart failure. 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.

The presence of an insufficient amount of amniotic fluid less than mL at term.

The evolution of the normal twin was satisfactory amnejo all the pregnancy. References in periodicals archive? We concluded that it was a olifohidramnios 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. Monochorionic diamniotic twin pregnancy with selective IUGR type 2: A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in size between the foetuses.

The small baby, whose AC was still under the 5th centile, presented now oligohydramnios with a deepest vertical pool of 1 cm Figure 2. During the fetoscopy, we performed a sequen tial laser placental ablation, identifying first the anastomoses and then burning along the placental equator. Physiopathologically, the selective IUGR appears as a consequence of an unequal distribution of the placental mass between both twins.

This loss of blood into the small baby through the A-V anastomosis causes a reduced oxygenated blood flow to the healthy baby. Reporte de tres casos. Her neurological development has been adequate 6 months of age. The reason was a marked discrepancy in the growth of both twins Figure 1 and abnormal Dopplers in the small twin.

Los efectos secundarios asociados a la quimioterapia son principalmente constitucionales maternos, sin embargo existe importante asociacion de esta con restriccion del crecimiento intrauterino, oligoamnios y alteraciones cardiacas por lo cual se requiere seguimiento continuo y periodico principalmente a traves de la ecografia, siendo el ecocardiograma fetal indispensable en estas pacientes como parte del manejo prenatal integral de alto riesgo.

The big baby remained with normal Dopplers. 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.

Its etiology is due to a chronic blood transfusion from de donor twin to the recipient twin through the vascular anastomoses between the placental territories of both fetuses. Estudio oligohicramnios entre las concentraciones de cadmio y de plomo en placentas de embarazos normales y placentas de embarazos con oligoamnios idiopatico. Serial transvaginal sonographic measurement of cervical dimensions after 20 weeks of gestation in South Indian women. 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.

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.

Resultante materno-perinatal del oligohidraminos doble en el hospital gineco-obstetrico “Enrique C. Fetal Medicine Foundation Conflict of interest: Among these complications we have the twinto-twin transfusion syndrome, the olibohidramnios fetal growth restriction, the twin anaemia polycythemia sequence, the twin reversed arterial perfusion sequence and the monoamniotic pregnancy 1.

Considering the deterioration of the small twin amniotic fluid and Dopplers and its high chance of intrauterine demise, we decided to perform the fetal surgery mainly to protect the wellbeing of the healthy baby thus avoiding the consequent exsanguination of this twin through the placen-tal anastomoses.

Received for publication 22 June and accepted oligohhidramnios publication on 10 July The vascular anastomoses in monochorionic twin pregnancies and their clinical consequences.
