目的 建立胎儿左、右肺面积及肺头比的正常参考值范围。方法 对501例正常单胎妊娠12～40周胎儿在标准四腔心切面应用手工描绘法分别描迹左肺、右肺面积,分别除以头围获得左、右肺头比。结果 获得正常妊娠胎儿左、右肺面积及肺头比各孕周参考值范围。胎儿左、右肺面积及肺头比均随孕周的增长而增大。结论 正常妊娠胎儿左、右肺面积及肺头比与孕周呈正相关。不同孕周LHR参考值的建立有利于临床评价膈疝及其他胸腔占位性疾病的预后。

Objective To establish reference intervals for fetal left and right lung areas and lung area to head circumference ratio (LHR). Methods In 501 cases of normal singleton pregnancy between 12 to 40 weeks, the left and right lung areas were measured respectively by ultrasound in the standard four chamber view, using manual tracing of the limits of the lungs. The left and right LHR were calculated when head circumferences were divided by the left and right lung area. Results Normal fetal reference intervals of left and right lung areas and LHR with gestational age were obtained. Fetal left and right lung areas and LHR increased with gestational age. Conclusion Fetal left and right lung areas and LHR values positively correlated with gestational age in normal pregnancy. Normal reference intervals of fetal LHR for every gestational age are valuable for evaluation of prognosis of fetal diaphragmatic hernia and other pulmonary peripheral space-occupying lesions.

       目的   比较宫腔镜病灶切除术与超声监测下吸宫术治疗剖宫产瘢痕部位妊娠（CSP）的有效性。方法   回顾性分析2021年7月—2023年10月在南宁市妇幼保健院确诊为I、Ⅱ型CSP并接受治疗的129例患者，停经时间在38～83 d，中位停经时间48 d。其中42例患者接受了宫腔镜病灶切除术治疗（A组），87例患者接受超声监测下吸宫术治疗（B组），比较两组患者术后1、3、7、14 d的人绒毛膜促性腺激素水平以及手术出血量、手术时间、住院时间、住院花费。结果   两组患者在术后1 d，血清HCG水平下降，下降幅度均超过50%，且A组患者术后1 d血清HCG的下降幅度及下降速率大于B组患者（P＜0.05）；术后3、7、14 d，两组血清HCG水平仍持续下降。另外，A组患者手术出血量、手术时间、住院时间、住院花费分别为（15.35±14.53）mL、（60.73±53.05）min、（4.33±1.90）d、（6 689.23±2 216.19）元；B组患者手术出血量、手术时间、住院时间、住院费用分别为（26.09±29.24）mL、（51.59±54.46）min、（4.82±1.83）d、（6 270.34±2 547.85）元。A组患者术中出血量低于B组、住院时间短于B组（P＜0.05），手术时间及住院费用与B组比较差异无统计学意义（P均＞0.05）。结论   宫腔镜病灶切除术与超声监测下吸宫术均能有效治疗CSP，但宫腔镜病灶切除术在术后血清HCG的下降幅度及下降速率、术中出血量、住院时间等方面优于超声监测下吸宫术，而且手术时间和住院费用并没有显著增加。
