Sonographic Estimation of Gestational Age by using Transcerebellar Diameter in Second and Third Trimester of Pregnancy
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2015, Vol 3, Issue 9
Abstract
The accurate knowledge of gestational age is a keystone in an obstetrician's ability to successfully manage the antepartum care of a patient and is of critical importance in ante-natal tests and successful planning of appropriate therapy or intervention. Failure can result in iatrogenic prematurity which is associated with increased perinatal morbidity and mortality. Ultrasonography of fetal measurements is highly reliable in the first and second trimester of pregnancy but reliability of any ultrasound method greatly diminishes as gestation advances. The objective is to estimates GA by using transcerebellar diameter in second and third trimester. A descriptive analytical cross sectional study done in different Khartoum hospitals from February to September 2014. The data was collected, classified, analyzed by using SPSS, results shows that most women under study their ages groups between 20-30years and this forms incidence of about 49%, from central Sudan (32%), house wife (75%), para2-5 (51%), gravid less than 5 (54%), LMP the irgestation age was 25-29 (27%), BPD was 25-29 (28%)and by TCD their gestation age was 30-34 (28%). The accuracy of TCD in detection of GA is constant throughout the second and third trimesters of pregnancy. The study recommended that the transcerebellar diameter can be used as accurate nomogram in the second and third trimester. Keywords: Ultrasonography, fetal measurements, transcerebellar diameter
