Estimation of Gestation Age by Cerebellum Diameter Using Ultrasonography

Abstract

This a descriptive crossectional study which aimed to Estimate of Gestation age by Cerebellum Diameter using Ultrasonography carried out in Ribat Teaching hospital, Khartoum state - Sudan, from November 2016 to May 2017. There were 49 pregnant ladies selected conventionally scanned by Siemens ultrasound machine, all cases were normal pregnancy in second or third trimester, any female had pregnancy in first trimester or with fetal anomaly was excluded from this study. Transabdominal scaning was performed for all cases to evaluate transverse cerebellum diameter (TCD), biparietal diameter (BPD), femur length (FL), head circumference (HC), abdominal circumference(AC). Collected data was analyzed using statistical package for the social sciences ( SPSS). Study resulted that; mean value of the TCD was 35.102 ± 367mm, mean of BPD was 70.435mm ± 18.2mm, mean of FL52.949 mm+/- 18.2mm, mean of HC was 251.348 ± 73.2971mm and mean of AC 228.382mm ± 81.5224mm. Study showed that there was a direct linear correlation between gestational age and TCD, BPD, FL, AC and HC, in which gestational age increased by 0.5254 week /mm, 0.38 week/ mm, 0.3957 week/mm, 0.0784 week/ mm , 0.0813 week/mm respectively. Also study showed that there was significant strong positive correlation between TCD with BPD, FL, AC, HC 0.955, 0.948, 0.914,0.866 respectively at PV= 0.000. Study Recommended that pregnant women who in second or third trimester should be measured gestational age using Trans Cerebellum diameter as another parameter.
