孕中期高危孕妇外周血中胎儿游离DNA与高危产前诊断指征相关性分析
Zhongguo shiyan zhenduanxue, 2021 目的分析孕中期高危孕妇外周血中胎儿游离DNA(Cell-free fetal DNA,cffDNA)与高危产前诊断指征相关性。方法研究对象为2018年7月-2019年7月在遂宁市中心医院产前诊断中心接受外周血cffDNA筛查的3176例孕中期高危孕妇,记录高危产前诊断指征、cffDNA检测结果,分析不同高危产前诊断指征的孕中期高危孕妇外周血cffDNA筛查结果,以染色体核型检查结果为对照,分析孕中期高危孕妇外周血中cffDNA的筛查价值。结果3176例孕中期高危孕妇的产前诊断指征分别为高龄(年龄≥35岁)

Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa
Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.
