[Monozygotic multiple pregnancies with acardiac anomalies].
The acardiac fetus is a rare anomaly of about 1 percent of monozygotic pregnancies, occurring in approximately 1 in 35,000 pregnancies. The special hemodynamic circumstances of the normal heart having to pump an excessive amount of blood for a long period of time will influence the chance of survival of this fetus. In two case-report with many figures pathologic-anatomical problems and prospective management to improve the outcome of monozygotic multiple pregnancies complicated by acardiac malformation were presented. The pathogenesis of metabolic dysbalance in these pregnancies was discussed.
