Özet

Objective: This is a retrospective study accomplished to determine the efficiency of the first trimester ultrasound examination especially when performed on elective conditions. Materials and Method: The records of patients who had undergone early first trimester transvaginal ultrasound in Obstetrics and Gynecology Department of Cerrahpasa School of Medicine, Istanbul University between from January 1999 to December 2000 were reviewed. The records of 426 patients were eligible for the analysis. The age, parity, gestational week that the ultrasound performed, the complaint on appliance, the features visible on the ultrasound were noted. The patients were divided into two groups: patients without any complaint (Group 1) and patients applied with any complaint (Group 2). The prognosis of the pregnancy was determined through the follow-up. On the statistical analysis, χ-square test, student-t test, Pearson correlaton analysis and multiple linear regression analysis were utilized. Results: In group 1, 79% of examinations were normal whereas the rate of normal ultrasound was 50% in group 2. The difference between the groups was statistically significant (p=0.000). On group 1, 7 subsequent abortions, 7 missed abortions and one case of mole hydatiform were identified (7.6%). When the patient applied with a complaint, ultrasound examination revealed abnormal findings that enabled to reach an accurate diagnosis in 29.9% of these patients. 50 abortions (inevitable or incomplete), 13 missed abortions, 3 ectopic pregnancies and 2 mole hydatiform were diagnosed. The difference between the two groups according to ability to reach a diagnosis on the initial ultrasound was statistically significant (p=0.000). Conclusion: The value of ultrasound examination before the 10th weeks of pregnancy is not validated when the patient has no complaint even if it appears as the most powerful mean to assess the accurate gestational age and observing fetal cardiac activity is the best prognostic variable for the outcome of the fetus.
