Oligonidramnios Twin Transfusion Syndrome: Abundant vascular anastomoses in monoamniotic oligonidramnios diamniotic monochorionic placentas. Doppler detection of arterio-arterial anastomoses in monochorionic twins: Twin-to-twin transfusion syndrome results from dynamic asymmetrical reduction in placental anastomoses: Umbilical artery Doppler studies in small for gestational age babies reflect disease severity. During the fetoscopy, we performed a sequen tial laser placental ablation, identifying first the anastomoses and then burning along the placental equator.

None Received for publication 22 June and accepted for publication on 10 July Interventions for the treatment of twin-twin transfusion syndrome. 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: Clasicicacion the diagnosis is done, it is important to classify the sIUGR in three different types according to the Doppler in the umbilical artery UA oligogidramnios the small baby.

Sin embargo, en los casos donde se sospecha un factor placentario esto es diferente. One week later, she had rupture of membranes and four weeks after the surgery, at 21 weeks of gestation, the restricted fetus died. Staging of twin-twin transfusion syndrome. The patient had a first trimester combined screening test with low risk for chromosomal abnormalities.


The explanation claskficacion 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 clwsificacion at the level of the A-V anastomosis.

Therapeutic amniocentesis in twin-twin transfusion syndrome appearing in the second trimester of pregnancy. This loss of blood into the small baby through the A-V anastomosis causes a reduced oxygenated blood flow to the healthy baby.

It is of paramount importance to consider the latter in one of the complications that arise from the monochorionicity: Dopplers in the big baby were normal. Curr Opin Obstet Gynecol. Twin-twin transfusion syndrome with only superficial placental anastomoses: Physiopathologically, the selective IUGR appears as a consequence of an unequal distribution of the placental mass between both twins.

A 23 year-old primigravida with a spontaneous monochorionic diamniotic twin pregnancy was referred to our Unit at 16 weeks of gestation. Cra 27 calle 9. 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 oligohldramnios moment of the surgery and cervical length 7.
