Constriction Ring Syndrome, also known as Amniotic Band Syndrome (ABS), is a congenital condition that occurs when fibrous bands from the amniotic sac entangle parts of a developing fetus, typically the limbs or digits. These bands can restrict blood flow and impede normal development, leading to a range of deformities that vary in severity. The condition can result in anything from mild indentations on the skin to more severe complications, such as deep constrictions, amputations of fingers, toes, or limbs, and in some cases, craniofacial abnormalities.

It’s also known as amniotic band syndrome. More commonly the bands wrap around limb, fingers or toes, creating severe constrictions. It need early attention by ring / band excision and z plasty to restore venous and lymphatic drainage and limb growth.
