title: Clinical course of early fetal loss and its chromosomal characteristics.
abstract: The relationship between types of chromosomal abnormalities and fetal development documented by ultrasonography was discussed in early spontaneous abortions. The subjects were 113 patients who had vaginal ultrasonography at least twice between 6 and 8 weeks of pregnancy, among 167 abortuses with chromosome analyzed. The results were also compared against those for 303 normally developing fetuses. The results obtained in the present study suggested that each fetus with a chromosomal abnormality succumbed at or after a specific stage of fetal development and that the fetal death might be the results of severe fetal growth suppression.
