1/136. radius hypoplasia, radial palsy, and aplasia cutis due to amniotic band syndrome. amniotic band syndrome is one of the many causes of aplasia cutis congenita. It is usually seen as a constriction band surrounding a limb or as a membrane that adheres to some part of the body. This syndrome can be associated with various malformations. An infant with amniotic adhesions producing aplasia cutis, radial palsy, and hypoplasia of the radius is presented. Early treatment led to total functional recovery of the affected limb. ( info) |
2/136. Circumferential abdominal skin defect possibly due to umbilical cord encirclement. We report on a newborn black male twin with a distinctive circumferential abdominal skin defect who was identified through the Active Malformation Surveillance Program at the Brigham and women's Hospital. There were no other malformations, and amniotic disruption was not present. Although it cannot be proven, we believe that this skin defect may have been caused by in utero encirclement of the abdomen by an umbilical cord. ( info) |
3/136. An unusual presentation of constriction band syndrome. Congenital constriction band syndrome is a rare entity with a wide spectrum of associated congenital anomalies. review of the pathogenesis and an unusual case of constriction band syndrome in a newborn are presented. Surgical excision of the deformity and the band was performed within the first week of life. There were no vascular or neural structures within the excised tissue, and there were no other associated anomalies other than dextrocardia and an equinovarus deformity of the foot. The wound was closed primarily without the need for Z-plasties. This alternative method of treatment can be considered in such unusual locations of constriction band syndromes. ( info) |
| A case of amniotic band syndrome (ABS) presenting with acalvaria is reported. ABS includes a spectrum of non-genetic anomalies, varying from simple digital band constriction to major craniofacial and visceral defects, and even fetal death. Acalvaria is a rare congenital malformation characterised by the absence of the dome-like superior portion of the cranium comprising the frontal, parietal, and occipital bones and dura mater, in the presence of a normal skull base and facial bones with complete cranial contents. No two cases are the same. Acrania or absence of the flat skull bones with disorganised cerebral hemispheres have been reported in the presence of amniotic bands. ABS is an aetiological factor in acalvaria. Appropriate counselling for affected families needs to be given after prenatal diagnosis. ( info) |
| We present a case of amniotic band syndrome leading to encephalocele in one triplet. In this case, discordance in fetal growth was observed at 9 weeks' gestation, and the amniotic membrane was not recognized in the sac of the smallest fetus. Thus, significant first-trimester growth discordance in multifetal pregnancies suggests congenital anomalies, and examinations considering amniotic band syndrome should be performed. Absence of the amniotic membrane in the gestational sac may be a useful marker of amniotic band syndrome. ( info) |
6/136. Intrauterine sling: a complication of the stuck twin syndrome. Stuck twin syndrome usually presents with polyhydramnios in the recipient sac and severe oligohydramnios in the donor sac. The donor is displaced against the uterine wall and remains adherent in that position. We present a case in which the diagnosis was more complicated, owing to the suspension of the stuck twin by a sling within the sac of the recipient. A monochorionic diamnionic twin gestation was complicated by twin-twin transfusion syndrome at 18 weeks of gestation. In our example, the stuck twin was suspended by a sling from the placenta. The sling band represented the intertwin membrane that was folded upon itself. amniotic fluid from the recipient twin was present in three dimensions around the stuck twin, except for the sling band. The suspension of the stuck twin by a sling within the amniotic fluid of the recipient is an unusual manifestation of the stuck twin syndrome. ( info) |
| amniotic band syndrome (ABS) comprises fetal morphological abnormalities that may be associated with fibrous amniotic bands that damage developing fetal parts resulting in cutaneous scars, erosions and ulcerations, digital constricting bands, craniofacial and visceral anomalies. Multiple asymmetric encephaloceles and anencephaly are neural-tube-like defects previously reported with ABS. This is the first report of spinal dysraphism with dorsal spinal cord tethering associated with ABS. We examine the pathogenetic theories of ABS in light of this report. ( info) |
| At 16 weeks' gestation, ultrasonography demonstrated a band-like structure in the amniotic cavity of a 27-year-old woman. color Doppler imaging revealed blood flow in this band-like structure and a diagnosis of a placenta with succenturiate lobe rather than an amniotic band was made. ( info) |
9/136. Severe constricting ring syndrome: case report. This report presents a case of a male newborn with a severe circumferential amniotic band, treated by single-stage excision of the ring, and microvascular venous anastomosis between the proximal and distal parts of the affected site. No complications were encountered. A microsurgical approach to improve the circulation may be useful in some cases. ( info) |
10/136. constriction band of the arm following insertion of a pleuro-amniotic shunt. In a 23-week fetus with a large left-sided pleural effusion a double pigtail pleuro-amniotic shunt was inserted uneventfully. A healthy infant was delivered at 38 weeks' gestation. One end of the shunt was in the thoracic cavity but the other end was found wrapped around the upper arm resulting in a constriction band. There was no impairment of the vascular supply to the limb or in its motor or sensory function and by 6 months of age there was only a faint ring still apparent around the upper arm. ( info) |
