Background: Per vaginal bleeding in the first trimester is a common obstetrical situation ranging from an insignificant episode to life threatening emergency. The major causes are abortion, ectopic and molar pregnancies. Objectives of study: Ultrasonography is playing an increasing role in diagnosis of causes of Per vaginal bleeding in the first. This study was taken up to evaluate the value and utility of ultrasonography in correlation to the clinical findings of Per vaginal bleeding in the first trimester (sonographic evaluation). Materials and Methods: In this prospective study all obstetric cases (with a history of per vaginal bleeding in the first trimester of pregnancy between April, 2015 to November, 2015 (of 8 months) were included. A complete general physical examination including pelvic examination was done to arrive at a clinical diagnosis. Patients were then subjected to ultrasound examination. Clinical and ultrasound findings were correlated. We attempted to indentify the causes of vaginal bleeding occurring in the first trimester by clinical and trans-abdominal sonography and to evaluate the outcomes after instituting appropriate obstetric management. Results: Fatytun of all obstetric cases (200) had the First trimester bleeding (incidence being 21%). The common causes were abortion (85.68%), molar (9.52%) and ectopic (4.80%) pregnancies. The bleeding cases were common in the younger age group 21 to 25years, more in the multigravida within 5 to 8(47%) weeks of gestational age. The commonest cause of bleeding was threatened abortion (28.57%). Early institution of treatment after proper diagnosis has decreased morbidity, at times mortality of women. Ultrasound had not only clinched the diagnosis but also helped in timely management of first trimester vaginal bleeding. Conclusion: Ultrasound is a simple, non-invasive diagnostic modality available in the current day practice to diagnose and to manage first trimester vaginal bleeding.

A two-dimensional ultrasonic B scanner is used to diagnose both single and multiple early pregnancy The contact scanning method is used. The patient is required to have a full bladder if she is under 14 weeks gestation. The uterus and the cervix are outlined. Then a search is made for the gestation sac or sacs within the uterine cavity if the cyesis is under 10 weeks. Serial longitudinal and transverse scans are carried out to outline the gestation sacs. The fetal echoes within the gestation sac are seen and the fetal heart rate can be detected using the time-position display (TP). The patients that are studied fall into the following groups: (1) patients who are clinically suspected to have multiple pregnancy; (2) patients who have been on ovulation induction therapy; (3) patients with family history of twins; (4) patients with threatened abortion. The diagnosis of multiple pregnancy during the 11th week is equivocal. After the 12th week gestation the diagnosis is made by visualising the fetal head and the maturity is then estimated by measuring the biparietal diameter. Thus fetal growth can be assessed by carrying out serial biparietal diameter estimations.
