[Problems posed by the death of one fetus in a twin pregnancy]

Much recent works has highlighted the problems posed by the death of one fetus in utero during multiple pregnancy. This is a rare but serious accident which exposes the mother and the surviving fetus to the transfer of placentary and fetal thromboplastins or to the direct embolization of necrosed fragments of the placenta. Only fetal death occurring during the second and third terms of pregnancy is considered.
