Abstract: Objective To report 1 case of fetal death induced by amniotic band syndrome ，explore the amniotic band syndrome associated malformations associated factors and diagnosis．Methods Results In this case, the amniotic band syndrome is expressed as the amniotic band attached to the root of the umbilical cord.Although not lead to deformity of the appearance of the fetus,but causing abnormal umbilical cord, umbilical cord occlusion resulting in fetal death in utero, it is rare.This example stay after successful induction delivery of the dead fetus, repeated inspection to exclude other fetal malformations. Placenta, umbilical cord careful examination, repeatedly asked in detail about the history, because the patient refused further chromosome examination, the amniotic membrane with causes of this syndrome is not clear.Results Amniotic band syndrome is a rare clinical disease. the amniotic membrane with causes of this syndrome is not clear. Conclusion Amniotic band syndrome is a rare clinical disease. Amniotic band syndrome mainly for outer surface of tissue and organ defects; involvement of tissue and organ because of its occurrence in the critical period，because of the amniotic sac and amniotic membrane rupture with adhesions interference and teratogenicity; the severity of the deformity and range depends on the amnion rupture time and site．we have to strengthen the understanding of this disease through rare clinical cases, and accumulated valuable experience.
