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. And second, an effective ultrasound-fetoscopic correlation that let us assess the progression of the disease and decide the most appropriate moment to intervene considering the ultrasound and feto scopic findings already described and yet to be studied.

The diagnosis was consistent: The diagnosis is based on exhaustive echographic examination of both fetuses to make an early diagnosis and correct staging, since the prognosis depends very much on early action.

Received for publication 22 June and accepted for publication on 10 July The patient had a first trimester combined screening test with low risk for chromosomal abnormalities.

The cervix was long and closed, no funnelling, and measured 30 mm Figure 5. The patient was discharged the same day of the surgery after checking the cardiac activity in both babies. As we mentioned before, the shared placental circulation between both babies produce complications inherent to this type of twinning.

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.

After the counselling, the patient accepted the surgery and signed the consent forms. Posteriormente, Rodriguez y Palacios, enencontraron caracteristicas similares en la secuencia de deformacion por acinesia oligohidfamnios y la secuencia de oligoamnioscomo la artrogriposis, el cordon umbilical corto y la hipoplasia pulmonar 4.

Oligoamnios by Rolando Hernandez Cordova on Prezi

It is of paramount importance to consider the latter in one of the complications that arise from the monochorionicity: 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. Therefore we proceeded to burn oligohhidramnios in order to avoid any possible blood loss from the normal twin into the oligohidra,nios one.


Placental sharing, birthweight discordance, and vascular anastomoses in monochorionic diamniotic twin placentas. Estudio comparativo entre las concentraciones de cadmio y de plomo en placentas de embarazos normales y placentas de embarazos con oligoamnios idiopatico. Oligoamnios definition of oligoamnios by Medical dictionary https: Management of twin-twin transfusion syndrome in monochorionic twin gestations.

A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in olihohidramnios between the foetuses. 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. 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 treatment of choice is fetoscopic laser coagulation of vascular anastomoses between 18 and 26 weeks of gestation. Linfoma No Hodgkin y embarazo.


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.

The management is generally surgical since the prognosis without doing anything is poor: Case A 23 year-old primigravida with a spontaneous monochorionic diamniotic twin pregnancy was referred to our Unit at 16 weeks of gestation.

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.

Therefore, placental anastomoses play an important role in the development of this condition 3. The small baby, whose AC was still under the 5th centile, presented now oligohydramnios with a deepest vertical pool of 1 cm Figure 2. The vascular anastomoses in monochorionic twin pregnancies and their clinical consequences.

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. Rev Cubana Obstet Ginecol [online]. Reporte de tres casos.


A sample oligohidramniow amniotic fluid was obtained for karyotype that turned out to be normal. We considered this finding a consequence of the low central vascular pressure in the sick foetus and its placental umbilical arterial branches, not able to overcome the pressure of the umbilical venous branches of the normal foetus at the level of the placental anastomoses.

Monochorionic pregnancies pose a great challenge for the fetal medicine specialist in terms of prevention, diagnosis and management due to the shared placental circulation by both twins. Selective intrauterine growth restriction in monochorionic diamniotic twin pregnancies.

The presence of an insufficient amount of amniotic fluid less than mL at term. First, a thorough week scan that allow us to establish clearly the chorionicity and amnionicity of the pregnancy, as well as satisfactory CRL and NT measurements. 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 loss of blood into the small baby through the Oligohdiramnios anastomosis causes a reduced oxygenated blood flow to the healthy baby. Los Dopplers en el gemelo grande eran normales. Each of these types has different placental characteristics, management and prognosis 1.

Monochorionic diamniotic twin pregnancy with selective IUGR type 2: The oligohidtamnios was a marked discrepancy in the growth of both twins Figure 1 and abnormal Dopplers in ollgohidramnios small twin.

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 oligohisramnios 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.
