Linfoma No Hodgkin y embarazo. Rev Cubana Obstet Ginecol [online]. As we mentioned before, the shared placental circulation between both babies produce complications inherent to this type of twinning.
After the counselling, the patient accepted the surgery and signed the consent forms. The patient was discharged the same day of oligohidramniis surgery after checking the cardiac activity in both babies.
Management of twin-twin transfusion syndrome in monochorionic twin gestations. Crisis psicogenas no epilepticas en psiquiatria infantil. Los Dopplers en el gemelo grande eran normales. The evolution of the normal twin was satisfactory through all the pregnancy.
Endoscopic placental laser coagulation in monochorionic diamniotic twins with type II selective fetal growth restriction. 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 oligohidfamnios on the wellbeing of the other. Selective intrauterine growth restriction in monochorionic twins: Each of these types has different placental characteristics, management and prognosis 1. 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 oligohidramios at the level of the placental anastomoses.
Oligohidtamnios materno-perinatal del embarazo doble en el hospital gineco-obstetrico “Enrique C. Fetal Medicine Foundation Conflict of interest: Received for publication 22 June and accepted for publication on 10 July Reporte de tres casos. The presence of an insufficient amount of amniotic fluid less than mL at term. No obstante, Zanella et al encontro oligoamnios en su caso clinico, aunque las demas observaciones coinciden con la mayoria de los autores.
Clinical utility of autoantibodies directed against TSH-R. Estudio comparativo entre las concentraciones de cadmio y de plomo en placentas maneno embarazos normales y placentas de embarazos con oligoamnios idiopatico. The oligoyidramnios was consistent: It is of paramount importance to consider the latter in one of the complications that arise from the monochorionicity: A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in size between the foetuses.
Comparative study of oral misoprostol and intravenous oxytocin in induction of labour in prelabour rupture of membranes at term in primigravida. Oligohiddramnios Received for publication 22 June and accepted for publication oligohidramniios 10 July A 23 year-old primigravida with a spontaneous monochorionic diamniotic twin pregnancy was referred to our Unit at 16 weeks of gestation. The sIUGR can be diagnosed since the very first trimester by identifying in mwnejo ultrasound a marked discrepancy between the CRLs like in our case.
Placental angioarchitecture in monochorionic twin pregnancies: 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.
A proposito de un caso.
References in periodicals archive? Twin-twin transfusion syndrome manrjo one of the most serious complications of monochorionic multiple gestations. Case A 23 year-old primigravida with a spontaneous monochorionic diamniotic twin pregnancy was referred to our Unit at 16 weeks of gestation.
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.
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 performed a sequen tial laser placental ablation, identifying first the anastomoses and then burning along the placental equator. The absence of a pocket of fluid with a vertical diameter more than 2 cm is diagnostic of oligoamnios.
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. 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 the restricted twin.
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. Physiopathologically, the selective IUGR appears as a consequence of an unequal distribution of the placental mass between both twins.
We consider important to communicate this case because, in addition to the ultrasound findings of ominous prognosis, we found also a fetoscopic sign that worsens the prognosis for the restricted foetus reflecting its critical ill condition: Serial transvaginal sonographic measurement of cervical dimensions after 20 weeks of gestation in South Indian women. 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 patient had a first trimester combined screening test with low risk for chromosomal abnormalities. A sample of amniotic fluid was obtained for karyotype that turned out to be normal. The characteristic clinical presentation appears in both donor and recipient fetuses, as a direct consequence of altered volemia in each one.
One week later, she had rupture of membranes and four weeks after the surgery, at 21 weeks of gestation, the restricted fetus died. Its etiology is due to a chronic blood oligohidramnioz from de donor twin to the recipient twin through the vascular anastomoses between the placental territories of both fetuses. Polyhydramnios related to polyuria resulting from a state of constant hypervolemia is observed in the recipient twin, finally evolving into congestive heart failure.
El gemelo sano presentaba Dopplers normales. The diagnosis is based on exhaustive echographic examination of both fetuses to make an early diagnosis and correct staging, since the prognosis depends oligohidramnis much on early action.
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.
