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.
