[Amniotic band disruption complex: report of one case in twins]

Amniotic band disruption complex is a congenital disorder with the principal features vary from simple digital band constrictions to major craniofacial and visceral defects. Early amniotic rupture results in multiply affected infants who are frequently aborted or stillborn, whereas later rupture results primarily in limb involvement. Here we report a case of amniotic band disruption complex, a male infant (twin A) weighing 2350 gm with Apgar scores of 9 and 10 at one and five minutes. The second, third and fourth fingers on the left hand appeared to have ring constrictions, the distal part of the fourth finger had been amputated distally. There were amputations and ring constrictions of the distal parts of the second, third and fifth digits on the right hand, the fourth finger had only proximal third. All of the toes on the left foot had been amputated distally. The fifth toe on the right foot were absent, and the others had been partly amputated. Left cleft lip and palate were present with sunken left nasal flare. This baby underwent the cranial ultrasound examination, which demonstrated on structural anomalies, and both of the twins had the karyotype of 46XY. No other abnormalities was noted in the infant. The 890 gm placenta was delivered spontaneously. Two umbilical cords were present, each with normal vessels. The examination of the placenta revealed it to be dichorionic and diamniotic, and numerous fibrous strings extending form the fetal surface.
