Abstract
This tool-assessment study was carried out to determine the predictive value of trans-abdominal ultrasonography in assessing integrity of lower uterine segment by measuring lower uterine segment scare thickness at term in patient with previous CS.
The mean age of the studied population was 26.7±2.9 years with 83.1% of them were below 30 years. The mean weight of the studied population was 81±4.97 kg with a range of 65-96 kg.About 12.4% of them had one or more previous abortions.
The mean duration from last CS of the studied population was 27.6±9.84 monthes with 43.8% of them had at least one previous CS. About 19.1% of the studied women had tender CS scar.
The mean gestational age was 38.5±0.59 weeks. The mean fetal weight was 3123.3±138.7 gram. The mean LUS scar thickness was 3.02±0.53 mm.
The mean fetal weight of the studied population was 3124.7±137.97 gram. The mean Apgar score of the newborns was 7.9±0.7. The mean LUS scar thickness measured by caliper was 2.5±0.48 mm.
The majority of them (84.4%) didn’t have any complications, while 15.6% had post-operative complications.
There was significantly lower sonographic LUS thickness in maternal age group ≥30 years than in maternal age group <30 years. There was significantly lower sonographic LUS thickness in the group with gestational age ≥38 weeks than in the group with gestational age <38 weeks.
There was significantly lower caliper LUS thickness in the group with gestational age ≥38 weeks than in the group with gestational age <38 weeks. There was significantly lower caliper LUS thickness in the group with birth weight >3000 gram than in the group with birth weight ≤3000 gram.
The potential factors associated with low LUS measurement in the studied women include maternal age ≥30 years (OR=11.8, p<0.0001), gestational age ≥38 weeks (OR=7.7, p=0.009), birth weight >3000 gram (OR=9.04, p=0.005).
The association between LUS scar thickness and significant variables in the studied women using multivariate regression analysis model include maternal age, gestational age, birth weight.
There is strong significant positive correlation between sonographic LUS thickness and caliper LUS thickness (r=0.95, p<0.0001).
