Fetal assessment in low risk pregnancy.
Síndrome de transfusión fetofetal
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. 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.
Dopplers in the big baby were normal.

Monochorionic diamniotic twin pregnancy with selective IUGR type 2: 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.

Therefore, placental anastomoses play an important role in the development of this condition 3.

As we mentioned before, the shared placental circulation between both babies produce complications inherent to this type of twinning. Cochrane Database Syst Rev. The role of Doppler velocimetry in the management of high risk pregnancies.
Fetal Medicine Foundation Conflict of interest: Enrique Gil Guevara gil doctors. A 23 year-old primigravida with a spontaneous monochorionic diamniotic twin pregnancy was referred to our Unit at 16 weeks of gestation.
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.
Renal injury from angiotensin II-mediated hypertension. 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 oligohidramniks.
A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in size between the foetuses. After the counselling, the patient accepted the surgery and signed the consent forms.

Chile Medwave Oct;8 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.
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.

Congenital malformations and intrauterine growth retardation: Jaypee Brothers Medical Publishers Ltd; 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 ed at the moment of the surgery and cervical length 7.
