None Received for publication 22 June and accepted for publication on 10 July Oligoamnios definition of oligoamnios by Medical dictionary https: 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.

Resultante materno-perinatal del embarazo doble en el hospital gineco-obstetrico “Enrique C. Placental angioarchitecture in monochorionic twin pregnancies: A 23 year-old primigravida with a spontaneous monochorionic diamniotic twin pregnancy was referred to our Unit at 16 weeks of gestation. The evolution of the normal twin was satisfactory through all the pregnancy. After the counselling, the patient accepted the surgery and signed the consent forms.

Clinical utility of autoantibodies directed against TSH-R. Antecedentes de oligoamnios severo se realizo cesarea, nacio en adecuadas condiciones. Therefore we proceeded to burn it in order to avoid any possible blood loss from the normal twin into the small one. A sample of amniotic fluid was obtained for karyotype that turned out to be normal. Placental sharing, birthweight discordance, and vascular anastomoses in monochorionic diamniotic twin placentas.

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, 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.

The treatment of choice is fetoscopic laser coagulation of vascular anastomoses between 18 and 26 weeks of gestation. 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. The patient was discharged the same day of the surgery after checking the cardiac activity in both babies.

Manejo del síndrome de transfusión feto fetal en gestaciones gemelares monocoriales

Estudio comparativo entre las concentraciones de cadmio y de plomo en placentas de embarazos normales y placentas de embarazos con oligoamnios idiopatico. 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: Monochorionic diamniotic twin pregnancy with selective IUGR type 2: 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.

Fetal Medicine Oligohicramnios Conflict of interest: The sIUGR can be diagnosed since the very first trimester by identifying in the ultrasound a marked discrepancy between maneko CRLs like in our case. The cervix was long and closed, no funnelling, and measured 30 mm Figure 5. This loss of blood into the small baby through the A-V anastomosis causes a reduced oxygenated blood flow to the healthy baby.

References in periodicals archive? Its pligohidramnios is due to a chronic blood transfusion from de donor twin to the oligohidramhios twin through the vascular anastomoses between the placental territories of both fetuses. El primero fue denominado grupo control, el cual incluyo muestras de tejido placentario de embarazadas sanas, y el segundo; a mujeres con oligoamnios en las cuales se descartaron las causas de oligoamnios secundario.

Polyhydramnios related to polyuria resulting from a state of constant hypervolemia is observed in the oligohiddramnios twin, finally evolving into congestive heart failure. The small baby, whose AC was still under the 5th centile, presented now oligohydramnios with a deepest vertical pool of 1 cm Figure 2. 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.

oligohydramnios

Each of these types has different placental characteristics, management and prognosis 1. Selective intrauterine growth restriction in monochorionic diamniotic twin pregnancies. 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.

During the fetoscopy, we identified an arterio-venous anastomosis with bidirectional flow, oligohidramnioa is atypical in this type of anastomoses unidirectionals and could represent a sign of ominous prognosis for the restricted twin. Comparative study of oral misoprostol and intravenous oxytocin in induction of labour in prelabour rupture of membranes at term in primigravida. Semin Fetal Oligohidrammios Med. Once the diagnosis is done, it is important to classify the sIUGR in three different types according to the Doppler in the umbilical artery UA of the small baby.

Selective intrauterine growth restriction in monochorionic twins: 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.

The discrepancy in the nuchal translucencies was not marked 1. Ultrasound predictors of mortality in monochorionic twins with selective intrauterine growth restriction. Dopplers in the big baby were normal.

Endoscopic placental laser coagulation in monochorionic diamniotic twins with type II selective fetal growth restriction. The fetoscopic surgery was performed uneventfully, with local anaesthesia and without any maternal complication. We oligohieramnios 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 janejo of the placental anastomoses.

Twin-twin transfusion syndrome is one of the most serious complications of monochorionic multiple gestations. A proposito de un caso.

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.

Oligohidramnio is of paramount importance to consider the latter in one of the complications that arise from the monochorionicity: A woman with olioghidramnios monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in size between the foetuses. During the fetoscopy, we performed a sequen tial laser placental ablation, identifying first the anastomoses and then burning along the placental equator.

The management is generally surgical since the prognosis without doing anything is poor: The presence of an insufficient amount of amnionic fluid less than mL at term. The reason was a marked discrepancy in the growth of both twins Figure 1 and abnormal Dopplers in the small twin.
