Amniotic constriction band, first described in 1832 by Montgomery1, is one term used to describe a wide range of associated congenital anomalies, including anular constrictions of multiple extremities, oligodactyly, acrosyndactyly, talipes equinovarus, cleft lip and cleft palate, and hemangiomas. Additional, less common clinical manifestations include complete absence of the limb, short umbilical cord, craniofacial disruptions, neural tube defects, cranial defects, scoliosis, and body-wall defects, such as gastroschisis and extrathoracic heart. Some of these manifestations are uncommonly noted at birth because they result in spontaneous abortion2-5.
The prevalence of amniotic constriction band is approximately one in 1200 to one in 15,000 live births6,7. The prevalence rate for male infants has been reported to be 0.91 and, for female infants, 1.44. These defects are reported to occur 1.76 times more frequently among African-Americans as compared with Caucasians6. Evidence of familial involvement is extremely rare. Although temporal and . . .
