【摘要】 胎儿体蒂异常(body stalk anomaly,BSA)是一种先天性致死性畸形,其临床表现为前腹壁大部缺损、内脏外翻、脊柱侧凸等多个器官和系统畸形。BSA的病因及发病机制尚不明确,可能与胚胎发育早期胚胎折叠异常、体壁缺陷闭合有关。据报道,BSA无性别或者家族倾向,也无已知的复发风险。目前多胎妊娠胎儿患BSA的文献报道很少,而三胎妊娠中只有一个胎儿患BSA的报道也很少。现回顾性报道1例三胎妊娠其中一胎为BSA,并最终行子宫下段剖宫产术的病例,以增强孕妇围生期保健意识,提倡妊娠早期行全面系统的超声检查以筛查出此类罕见的致死性疾病,从而改善母婴不良结局。更多还原

【Abstract】 Fetal body stalk anomaly(BSA) is a kind of congenital fatal malformation, which is clinically manifested by many organ and system malformation such as anterior abdominal wall defect, visceral valgus, scoliosis and so on. The etiology and pathogenesis of fetal BSA are still unclear, which may be related to abnormal embryo folding and defective closure of body wall in early embryonic development. Fetal BSA has been reported without gender or familial predisposition, and there is no known risk of recurrence. There are few reports of fetal BSA in multiple pregnancies and only one fetus in three pregnancies.Now retrospectively report one case in which a child is a three pregnancies BSA, and finally line cases of lower uterine segment cesarean section, pregnant women to enhance perinatal health care consciousness, promote the early weeks of pregnancy line comprehensive system of ultrasound in screening out this kind of rare fatal disease, to improve maternal adverse outcome and has certain practical value for clinical diagnosis and treatment at the same time.更多还原
