Bleeding Per Vaginum in First Trimester of Pregnancy-Role of USG Its Correlation with Clinical Assessment

Objective: Study was done to know the role of USG in first trimester bleeding per vaginum and to correlates the findings with clinical assessment.Material of Method: A hospital based cross sectional study was conducted over a period of 1 year between 1st July 2011 to June 2012 in the Department of Radio-diagnosis.Approved was obtained from the Institutional ethics review committees, AMCH.After clinical correlation patients are subjected to ultrasonography abdomen with full bladder for transabdominal examination.In required cases transvaginal examination in empty bladder was performed.Diagnosis was made by trans abdominal and transvaginal USG by using 3.5 Mhz, and 7.5 Mhz sector transducer respectively.Result: Ultrasound can diagnose viable and nonviable pregnancies accurately four weeks onwards.In our study intact pregnancy was found in 46%, incomplete abortion 24%, missed abortion in 7%, blighted ovum in 9%, complete abortion 2%, molar pregnancy 3%, ectopic pregnancy in 6% cases.Thus incomplete abortion was the commonest cause of vaginal bleeding among non viable pregnancies.Conclusion: In our study ultrasound proved to be more accurate than clinical diagnosis with sensitivity and specificity of 100%.Thus USG has opened new dimension in early pregnancy complication so that specific management can be immediately instituted.
