Comparative study of Ultrasonographic Evaluation of Vaginal Bleeding in Pregnancy with Clinical Examination

Abstract

Background:Vaginal bleeding is common in pregnancy. The causes for the vaginal bleeding cannot be evaluated by clinical and pelvic examination alone. Ultrasonography can has an important role in establishing the diagnosis. Materials and Methods:A prospective study was conducted in a tertiary care centre among 110 pregnant attending the OBG department with vaginal bleeding. The pregnant women with vaginal bleeding were evaluated both clinically and ultrasonographically.Results:Most of the women in this study belonged to 21 – 30 years of age. Abruptio placenta, Complete abortion, Incomplete abortion, ectopic gestation, intra uterine death, missed abortion, total placenta previa by clinical diagnosis were misdiagnosed as per ultrasonographic examination. The sensitivity of clinical diagnosis was 100%, specificity was 36.2%, PPV was 51.6% and NPV was 100% in comparison with the ultrasonography in the viable pregnancy. In non viable pregnancy, the sensitivity of clinical diagnosis was 92.9%, specificity was 25%, PPV was 46.4% and NPV was 83.3% in comparison to ultrasonography. Conclusion: Ultrasonography helps in establishing the diagnosis of vaginal bleeding during pregnancy.
