Ultrasonography was utilized for placental localization. Follow\u2010up revealed a fetal loss rate of 3.03 per cent with 1.96 per cent being spontaneous abortions. Patients with an anterior placenta had a fetal loss and spontaneous abortion rate of 4.06 per cent and 3\u00b705 per cent, respectively. No significant difference in the incidence of fetal loss (<jats:italic>p<\/jats:italic> &gt; 0\u00b71) or spontaneous abortion (<jats:italic>p<\/jats:italic> &gt; 0\u00b75) was found in patients having an anterior versus a posterior placenta.
