Perinatal Outcomes of Small for Gestational Age Infants in a Korean Tertiary Medical Center

PURPOSE: To examine the perinatal outcomes of small for gestational age (SGA) infants, compared with non-SGA infants and those born at 39 weeks, and to determine the optimal gestational age of delivery METHODS: We performed a retrospective cohort study (n=7,580) for births at a tertiary hospital. SGA was stratified into severe (below 5th percentile) and moderate (5~10th percentile) groups. Statistical comparison was performed using the χ2 test and multivariable logistic regression models. RESULTS: As compared to the non-SGA group at 38 weeks' births, the odds of sepsis were significantly increased in the moderate SGA group (OR 2.84, 95% CI, 1.12~7.20) and severe SGA group (OR 3.63, 95% CI, 1.14~11.58). In addition, the odds of respiratory distress syndrome at 41 weeks' births were significantly increased in moderate SGA (OR 15.32, 95% CI, 1.92~122.08) and severe SGA (OR 16.31, 95% CI, 1.18~226.14) groups, compared to it in the non-SGA group. The odds of other neonatal outcomes in the moderate SGA group were not significantly increased, as compared to the non-SGA group. However, the odds of neonatal intensive care unit admission and composite morbidity in the severe SGA group were significantly increased at 35, 36, 38, 39, 40, and 41 weeks' births, as compared to the non-SGA group. There was no significant difference in neonatal outcomes from 38 to 41 weeks in moderate SGA, and from 37 to 41 weeks in severe SGA. CONCLUSIONS: If there is no medical indication, delivery at 39 weeks can be considered in SGA pregnancies. However, delivery can be planned from 37 gestational weeks in severe SGA pregnancies,with a subjective finding of fetal compromise.

High-intensity focused ultrasound combined with hysteroscopic resection to treat retained placenta accreta

We present a case of retained placenta accreta treated by high-intensity focused ultrasound (HIFU) ablation followed by hysteroscopic resection. The patient was diagnosed as submucosal myoma based on ultrasonography in local clinic. Pathologic examination of several pieces of tumor mass from the hysteroscopic procedure revealed necrotic chorionic villi with calcification. HIFU was performed using an ultrasound-guided HIFU tumor therapeutic system. The ultrasound machine had been used for real-time monitoring of the HIFU procedure. After HIFU treatment, no additional vaginal bleeding or complications were observed. A hysteroscopic resection was performed to remove ablated placental tissue 7 days later. No abnormal vaginal bleeding or discharge was seen after the procedure. The patient was stable postoperatively. We proposed HIFU and applied additional hysteroscopic resection for a safe and effective method for treating retained placenta accreta to prevent complications from the remaining placental tissue and to improve fertility options.
