Amniotic Band Syndrome Face Defects, Cyclopia and Conjoined Twins
Amniotic band syndrome is a congenital condition in which bands of tissue can produce constriction grooves, limb loss and other abnormalities, including facial clefts. Its cause is unknown. A leading theory is that the amnion separates from the chorion early in pregnancy, leaving free bands. Reported frequency ranges from 1 in 1,200 to 1 in 15,000 live births. Associated abnormalities can include anencephaly and encephalocele, and reconstructive treatment can be complex. Cyclopia is the most severe form of holoprosencephaly, in which the brain fails to divide normally. It can involve one central eye and a tubular nose above it; the most severe cases die before or soon after birth. Conjoined twins occur in approximately 1.47 per 100,000 births. |

Re: Amniotic Band Syndrome Face Defects, Cyclopia and Conjoined Twins
These are excellent and most of them are properly identified. The two babies labeled as having anencephaly actually have a similar condition called exancephaly... the difference is that in anencephaly there is no covering over what's left of the brain. The baby in picture 5 is NOT a drug baby. It is probably a victim of amniotic band syndrome. The happens when the amniotic sac partially ruptures and pieces of it get stuck to or wrapped around the baby. If the baby swallows some, it can pull their whole face into horrible shapes and cause a misshapen head. Drug babies aren't horrific... they're just miserable and possibly brain-damaged, but other than being underweight they usually look normal. Good post! |

Re: Amniotic Band Syndrome Face Defects, Cyclopia and Conjoined Twins
Yeah, very good post and very good pictures. The problem is that a lot of pictures on the internet come with the wrong information, which is not your fault! |
