Case of resuscitation from cardiac failure by intrauterine transfusion after single fetal death in monochorionic twin pregnancy

Abstract In case of a single fetal death in monochorionic twin pregnancy, the surviving fetus is thought to become hypovolemic. However, there is no report of any evidence of fetal circulatory insufficiency in such cases. We present a case of a single fetal death in a monochorionic twin pregnancy with type III selective intrauterine growth restriction that involved low fractional shortening, high myocardial performance index, elevated pulsatility index in the middle cerebral artery and fetal ascites. After immediate intrauterine transfusion, each parameter improved promptly. The surviving baby grew up without cardiac and neurological complications. To the best of our knowledge, this is the first report on transient circulatory insufficiency and decreased cardiac function in the surviving fetus.
