Los Dopplers en el gemelo grande eran normales. A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a oligoihdramnios in size between the foetuses. 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.

Comparative study of oral misoprostol and intravenous oxytocin in induction of labour in prelabour rupture of membranes at term in primigravida.

The absence of a pocket of fluid with a vertical diameter more than 2 cm is diagnostic of oligoamnios.


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. 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.

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

As we mentioned before, the shared placental circulation between both babies produce complications inherent to this type of twinning. The characteristic clinical presentation appears in both donor and recipient fetuses, as a direct consequence of altered volemia in each one. The patient had a first trimester combined screening test with low risk for chromosomal abnormalities. The prognosis is variable, depending on the availability of fetal therapy and the gestational age at diagnosis, being prognosis generally very poor without an effective treatment.

The patient was discharged the same day of the surgery after checking the cardiac activity in both babies. We report the case of a MCDA twin pregnancy complicated with selective Oligkhidramnios, managed with fetoscopic surgery, in which we describe ultrasound criteria of severity and a oligohidarmnios sign of bad prognosis for the small twin: Therefore, placental anastomoses play an important role in the development of this condition 3.

Oligohidramnioe transvaginal sonographic measurement of cervical dimensions after 20 weeks of gestation in South Indian women. The management is generally surgical since the prognosis without doing anything is poor: None Received for publication 22 June and accepted for publication on 10 July The discrepancy in the nuchal translucencies was not marked 1.

Posteriormente, Rodriguez y Palacios, enencontraron caracteristicas similares en la secuencia de deformacion por acinesia fetal y la secuencia de oligoamnioscomo la artrogriposis, el cordon umbilical corto y la hipoplasia pulmonar 4.

Mmanejo fetoscopic surgery was performed uneventfully, with local anaesthesia and without any maternal complication. Fetal Medicine Foundation Conflict of interest: Once the diagnosis is done, it is important to classify the sIUGR pligohidramnios three different types according to the Doppler in the umbilical artery UA of the small baby. During the fetoscopy, we identified an arterio-venous anastomosis with bidirectional flow, which is atypical in this type of anastomoses unidirectionals and could represent a sign of ominous prognosis for manjo restricted twin.
