Congenital amputation is a congenital disorder that can be caused by amniotic band syndrome fibrous bands of the amnion that constrict foetus foetal limbs to such an extent, that they fall off due to missing blood supply. The child is born without one or more limbs or without parts of limbs Amelia birth defect amelia . Causes Congenital amputations can result from a number of causes. One common cause is amniotic band syndrome, which occurs when the inner fetal membrane amnion ruptures without injury to the outer membrane chorion . Fibrous bands from the ruptured amnion float in the amniotic fluid and can get entangled with the fetus, thus reducing blood supply to the developing limbs to such an extent, that the limbs can become strangulated, the tissues die and are absorbed into the amniotic fluid. Amnion ruptures can be caused by teratogenesis teratogenic drugs e.g. thalidomide , which causes phocomelia , or environmental chemicals ionizing radiation atomic weapons , radioiodine , radiation therapy infections metabolic imbalance Physical trauma trauma Treatment In rare cases, if diagnosed in utero, fetal surgery may be considered to save a limb which is in danger of amputation .

It is the opposite of polyhydramnios . Diagnosis Diagnosis is made by ultrasound measurement of the amniotic fluid index AFI 5cm. Several different methods exist for calculating AFI, that produce different index numbers below which oligohydramnios is said to be present. Causes It is typically caused by fetal urinary tract abnormalities such as bilateral renal agenesis Potter s syndrome , fetal polycystic kidneys, or genitourinary obstruction. Uteroplacental insufficiency is another common cause. Most of these abnormalities can also be detected by obstetric ultrasound. It may also occur simply due to dehydration of the mother, maternal use of angiotensin converting enzyme inhibitors, or without a determinable cause idiopathic . Complications Complications may include cord compression, musculoskeletal abnormalities such as facial distortion and clubfoot, pulmonary hypoplasia and intrauterine growth restriction.
