Objective: Bleeding during the first trimester of pregnancy is common and can be a sign of complication that often necessitates obstetric ultrasound for the assessment of the haemorrhage, and of fetal well being. The aim of this study was to determine the causes of first trimester bleeding on obstetrical ultrasound in our area. Method: It was a cross-sectional descriptive study during a six-month period from May to October 2017. All women who referred to the Regional center of medical imaging of Ngaoundere who agreed to participate in the study with first trimester bleeding were evaluated with clinical history and ultrasonography (US). Ultrasonographic exam was done via transabdominal or endovaginal approaches using GE LOGIQ 7 scanner brand. Microsoft Office Excel 2010 and SPHINX V 4.0 were used for data analysis. Results: A total of 121 of pregnant women who presented vaginal bleeding during the first trimester were enrolled into the study. These Ultrasound examinations represented 37.93% of all obstetric ultrasounds in the first trimester. The patients in this study ranged in age from 16 to 47 years with an average of 30 years. 50 (41.32%) were pregnant for the first time and 24 (19.83%) were primiparous. Mean gestational age was 9 weeks with the extremes of 5 and 12 weeks. 97 (80.2%) reported spontaneous bleeding while in 24 (18.8%) bleeding was mostly caused by sexual intercourse 11 (45.8%). Pelvic pain 91 (75.2%) was the most associated sign. 36 (29.8%) patients were diagnosed as threatened abortions. 27 (22.3%) were diagnosed with incomplete abortions. 4 (3.3%) cases showed an ectopic gestation. 9 (7.4%) cases showed complete abortions. Concordance between clinical diagnosis and ultrasound results was 84%. Conclusions: Bleeding in the first trimester of pregnancy is common in our area. Ultrasonography occupies a prominent place in the etiological diagnosis of bleeding in the first trimester of pregnancy; it is easy to find in most cases a responsible abnormality of bleeding.
