Abstract

The acardius occurs with an incidence of one in 35,000 births and is presumed to result hom vascular anastomosis between the arterial circulation of the hemodynamically larger ""pump"" twin and that of the recipient ""perfused"" twin. The perfused twin displays severe anomalies, typically referred to as acardia, that are incompatible with life. The pump twin, because of its expanded cardiac demand, may also deveolp cardiac failure, with a mortality risk of 50-70%. We experienced one case of acardiac-acephalus twin gestation diagnosed by antenatal ultrasonography, and presented this.
