Specific Therapy in Severe Fetal Intrauterine Growth Retardation: Failure of Prostacyclin

Two case histories of severe, early onset intrauterine growth retardation are presented. Intravenous prostacyclin was administered in an attempt to promote fetal growth and thus prolong the pregnancy, but was unsuccessful and resulted in intrauterine death in each case.
