Monochorionic, diamniotic twins with amniotic band syndrome at exactly the same site for each: A rare amniotic band syndrome presentation

Abstract
The aetiology of amniotic band syndrome (ABS) (Streeter's dysplasia, ADAM complex, amniotic deformities, adhesion, mutilation, amniotic band sequence, the amniotic disruption complex, annular grooves, congenital amputation, congenital constriction bands, transverse terminal defects of limb, aberrant tissue bands and amniochorionic mesoblastic fibrous strings amniotic bands) can present a wide range of clinical entities. The reported case concerns monochorionic, diamniotic twins with ABS at exactly the same site, which is extremely rare, raising questions about the aetiology of ABS. The twins had suffered from twin to twin transfusion syndrome (TTTS), where intra-uterine laser therapy had been performed at 20 weeks.
