A case of acardiac twinning where the pump twin dies in utero due to massiv
e thrombotic occlusion of umbilical arteries at a site of umbilical cord st
ricture of the intact twin. In acardiac twinning the morbidity and mortalit
y of the pump twin can be reduced by some invasive or medical approaches. T
he authors believe that in this interesting case the death of the pump twin
could not be prevented by antenatal treatment. (C) 2000 Elsevier Science I
