wahid to avoid this the woman mustn't have two or more fetuses but this is impossible !! right 😉 but at least we can avoid the mortality of fetuses or physical and neurological damage during pregnancy there are a various treatments : *Adjustment of amniotic fluid Serial ( amniocentesis) * Adjustment of blood supply by laser therapy (endoscopic surgery using laser to interrupt the vessels that allow exchange of blood between fetuses under the assumption that the unequal sharing of blood through these vascular communications leads to unequal levels of amniotic fluid.)or Umbilical cord occlusion
