Congenital amputation is birth without a limb or limbs, or without a part of a limb or limbs.
This article includes a list of general references, but it lacks sufficient corresponding inline citations. (August 2014) |
It is known to be caused by blood clots forming in the fetus while in utero (vascular insult) and from amniotic band syndrome: fibrous bands of the amnion that constrict fetal limbs to such an extent that they fail to form or actually fall off due to missing blood supply. Congenital amputation can also occur due to maternal exposure to teratogens during pregnancy.
