At the Department of Obstetrics and Gynecology of Catholic University in Rome 1257 pregnancies with vaginal bleeding in the first or second trimesters were ultrasonically observed. Pregnancy was found to be in normal development in 538 cases (42.80%); spontaneous abortion was reported in 688 cases (54.73%) and ectopic pregnancy, confirmed at surgery, in 31 cases (2.47%). The duration of bleeding appeared to have a significant effect on the prognosis of the pregnancy. Bleeding for 4 days or more predicted abortion almost significantly more often than a shorter bleeding episode. The spontaneous abortion rate increased with advancing maternal age and decreased with advancing gestational age. After detection of fetal life signs, the pregnancies ended in later abortion only in 9.29% of the cases. In this case there are no significant differences between normal or abnormal ultrasonic examinations. In our experience the ultrasound scanning, in patients with early pregnancy bleeding, is able to differentiate between live gestation or abortion but cannot predict the future.
在罗马天主教大学妇产科，对1257例孕早期或孕中期出现阴道出血的孕妇进行了超声观察。发现538例（42.80%）妊娠发育正常；688例（54.73%）报告为自然流产，31例（2.47%）经手术确诊为异位妊娠。出血持续时间似乎对妊娠预后有显著影响。出血4天或更长时间预测流产的可能性几乎明显高于出血时间较短的情况。自然流产率随孕妇年龄增长而升高，随孕周增加而降低。在检测到胎儿生命体征后，仅9.29%的病例妊娠最终以晚期流产告终。在这种情况下，正常或异常超声检查之间没有显著差异。根据我们的经验，对于孕早期出血的患者，超声扫描能够区分活胎妊娠或流产，但无法预测未来情况。
