Study on Ultrasonographic Parameters in Predicting Abortion in Patients between 6-12 Weeks of Pregnancy

Abstract

Background:The introduction of ultrasound into the obstetrical practice has been extremely useful in providing better understanding of the etiology of the first trimester spontaneous abortion and a basis for its clinical classification and management. The aims and objective of this study is to study the ultrasonographic parameters between 6 to 12 week of pregnancy in predicting early abortion, to assess the predictive value of ultrasonographic parameters in predicting early pregnancy and to study the associated maternal factor in present pregnancy in predicting early pregnancy loss. Subjects and Methods: The study included 120 patients attending OPD/emergency within 6-12 weeks of gestation, fulfilling the exclusion and inclusion criteria. Results: Out of 120 pregnancies, 24 pregnancies were non viable, out of which 41.66% were >30years of age. 62.5% of abortions occurred at 8-12 weeks of gestation. 17.5% females had abnormal gestation sac diameter, 6.60% females had abnormal crown rump length, 9.70 % females had abnormal yolk sac and 1 % had abnormal fetal heart rate. Conclusion: This study demonstrated that sonographic parameters, such as abnormal gestational sac diameter, small or large yolk sac diameter, abnormal Crown rump length and decreased fetal heart rate are associated with an increased likelihood of miscarriage. Combining these parameters may provide improved prediction of miscarriage.
