Objective : To study the prevalence of intrauterine adhesion [IUA] in women who underwent vacuum aspiration [VA] for treatment
of (cid:976)irst trimester abortion and associated factors that correlated with the occurrence of IUA.
Materials and Methods : This prospective study was performed in 81 women who were diagnosed with incomplete abortion,
inevitable abortion, embryonic death, blighted ovum, or death fetus in utero at Ramathibodi Hospital between May 2016 and April
2017. All patients underwent VA and of(cid:976)ice hysteroscopy was performed 12 weeks post-procedure to identify the occurrence of IUA.
Results : IUA were found in 14 women, which accounted for 17.3% of the participants. Most of the patients who had IUA were found
to be in stage I (9/14, 64.3%), followed by patients in stage II (3/14, 21.4%) and stage III (2/14, 14.3%). Abnormal menstrual
pattern after VA was found to be a statistically signi(cid:976)icant factor associated with IUA (odds ratio 6, 95% CI 2.95 to 12.55).
Conclusion : IUA occurred in women who underwent VA after (cid:976)irst trimester abortion and in those who had a history of abnormal
menstrual pattern after VA. Therefore, before performing VA for (cid:976)irst trimester abortion treatment, the patients should be informed
about the risks of developing IUA.
