Renal injury from angiotensin II-mediated hypertension. And second, an effective ultrasound-fetoscopic correlation that let us assess oligohodramnios 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.


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. Precoz antes de las 28 semanas.

Considering the deterioration of the small twin amniotic fluid and Dopplers and its high chance olgiohidramnios 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. 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.

We clasificwcion 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: A sample of amniotic fluid was obtained for karyotype claskficacion turned out to be normal.

This loss of blood into the small baby through the A-V anastomosis causes a reduced oxygenated blood flow to the healthy baby. The fetoscopic surgery was performed uneventfully, with local anaesthesia and without any maternal complication.

The role of Doppler velocimetry in the management of high risk pregnancies. 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.
