Abstract

Background: Intrauterine growth restriction (IUGR) and its early detection were correlated with a high risk of perinatal mortality and morbidity and management are helpful in decreasing the neonatal risks. Transcerebellar diameter to abdominal circumference ratio becomes a gestational age independent parameter, which may be helpful for early detection of IUGR. Objectives: Study the accuracy of transcerebellar diameter/abdominal circumference ratio (TCD/AC ratio) for the evaluation of normal fetal development. Patients and methods: Our Prospective observatory research included 500 women with uncomplicated pregnancy attending the outpatient clinic of Al Azhar university hospitals for routine antenatal care. Routine ultrasound parameters were measured as well as transcerebellar diameter. In all patients, the TCD/AC ratio was also determined. Results: Our study concluded that difference in TCD/AC ratio between patients with IUGR vs. patients with no IUGR is statistically significant with p value 13 this cutoff value with 99.03 % sensitivity and 83.45 % specificity, 58.0 with a positive predictive value and 99.7 with a negative predictive value. Conclusions: TCD/AC ratio seems to become an age-independent constant parameter and a comparatively good IUGR indicator in gestational age groups of 18-34 weeks which may be helpful for early identification of fetal intrauterine growth retardation (IUGR).
