Abstract:
Objective To explore the use of the transabdominal ultrasound with different frequency scanning anterior lower segment uterine scar situation for maternal guidance .Methods Pregnant women had a history of cesarean section 323 cases, and were lower uterine segment transverse incision .Of which seven cases of cesarean section were 8 months to 12 months, 49 patients 13 months to 24 months, 89 patients 25 months to 36 months, and more than 169 cases of 37 months.High-frequency ultrasound was use for ab-dominal and dynamic monitoring of different-year anterior lower segment uterine scar thickness and healing .Pregnancy outcomes ob-served were compared with surgery .Results With the extension of cesarean time , grade I uterine scar was also increased to 25~36 months (2 years ) which was the most obvious , and grade II and III scars were reduced accordingly .When group 25~36 months was used as the control group , there was statistically significant difference relative to group 8 ~12 months and 13 ~24 months ( P <0.01), but was no significant difference relative to group >37 months ( P >0.05).Among 323 cases, seven cases had uterine rup-ture that was confirmed by surgery with a rupture rate of about 2.1%.The rupture rate was about 28.6%in group 8~12 months, a-bout 2%in group 13~24 months, about 1.0%in group 25~36 months, and about 1.2%in group >37 months.When group 25~36 months was used as the control group , there was statistically significant difference relative to groups 8~12 months and 13~24 months ( P <0.01 ) , and was no significant difference relative to group >37 months ( P >0.05 ) .Conclusions Abdominal ultra-sound with different frequency scanning can monitor the thickness and continuity of anterior lower segment uterine scar to estimate the scar healing situation , and guide uterine scar grading .Therefore, it is great significance in guiding clinical decision of motherhood ap-proach.
