Abstract
Objective. This work aims to analyze the surgical timing and clinical efficacy of transvaginal cervical ring ligation based on the ultrasound image focus detection of patients with cervical insufficiency (CIC) under the ultrasound image theme generation model. Methods. 134 CIC patients who came to the hospital for ultrasound imaging diagnosis were collected. Observation group was treated with cervical cerclage (CC) and the pregnancy outcome was followed up. Control group was treated conservatively. Results. For patients in the control group, average gestational age was 21.12 ± 2.18 weeks, average cervical length (CL) was 15.54 ± 0.42 mm, and average uterine opening width was 3.06 ± 0.63 mm. In the observation group, average gestational age was 24.45 ± 4.12 weeks, average CL was 17.32 ± 4.09 mm, and average uterine opening width was 0.21 mm. There were significant differences between the two groups ( P < 0.05 ). There were also significant differences in the degree of uterine orifice dilation between the two groups ( P < 0.05 ). Pregnancy outcomes of the two groups were compared, and χ2 and P < 0.05 indicated significant differences. Conclusion. Convolution neural network (CNN) and long short-term memory model (LSTM) algorithm were used to classify patients' ultrasound images, which could effectively improve diagnosis and treatment efficiency. Surgical success rate, clinical outcomes, neonatal survival rate, and clinical effect of observation group were better than those of control group. Cervical ligation was best performed before 17 weeks of pregnancy in CIC.
Highlights
Patients with cervical insufficiency (CIC) is called intra-cervix relaxation, usually refers to the miscarriage or premature birth due to anatomy or defects in the uterus without obvious contractions
Fifty seven cases of neonates survived successfully, accounting for 85.1%. e survival rate of observation group was notably higher relative to controls (P < 0.05). e result was consistent with the results reported by McDermott et al [14] that CC for CIC was superior to vaginal progesterone in increasing the survival rate of newborns
Among the patients under investigation, in the observation group, 40 patients in group A were treated with CC before 17 weeks, 36 patients were successfully treated with a success rate of 89.6%, and 4 patients failed with a failure rate of 10.4%; in group B, 27 patients were treated with CC after 17 weeks, 19 patients were successfully treated with a success rate of 70.4%, and 8 patients failed with a failure rate of 29.6%. e observation group had a notably higher surgical success rate versus the control group, which indicated remarkable differences between the two groups (P < 0.05)
Summary
Patients with cervical insufficiency (CIC) is called intra-cervix relaxation, usually refers to the miscarriage or premature birth due to anatomy or defects in the uterus without obvious contractions. E recurrence rate of the disease is as high as 2%, which is about 3.3 times that of healthy women. Functional insufficiency usually refers to severe cervical damage caused by external effects, for example, the damage to the cervix during emergency labor, forceps, induced abortion, or curettage [3]. Cervical ring ligation is Scientific Programming currently an effective surgical method for the treatment of CIC, which can improve the perinatal outcome to a certain extent [7]
