Amniotic band constriction (also known as "amniotic band syndrome", "ADAM complex", "Amniotic band sequence", "Congenital constriction bands" and "Pseudoainhum") is a congenital disorder caused by entrapment of fetal parts (usually a limb or digits) in fibrous amniotic bands while in utero. ==Signs and symptoms== The constriction of appendages by amniotic bands may result in: # Constriction rings around the digits, arms and legs # Swelling of the extremities distal to the point of constriction (congenital lymphedema) # Amputation of digits, arms and legs (congenital amputation) A strong relationship between ABS and clubfoot (also called "talipes") exists. A 31.5% of associated clubfoot deformity and ABS can be correlated with 20% occurring bilaterally. Other abnormalities found with ABS include: clubhands, cleft lip, and/or cleft palate, and hemangioma. Decreased fetal movement could be a sign of a serious problem which may include ABS. It is rare but possible for the membrane to become wrapped around the placenta or the neck of the baby in the womb causing strangulation and death. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amniotic band constriction」の詳細全文を読む スポンサード リンク
