1/7. spinal cord tethering associated with amniotic band syndrome.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.- - - - - - - - - - ranking = 1keywords = anencephaly (Clic here for more details about this article) |
2/7. Open thoracic meningocele associated with amniotic band syndrome.We present a case of an infant born with an open thoracic meningocele secondary to an amniotic band. Although there have been several case reports of encephalocele, anencephaly, closed meningocele and a case of tethered cord associated with amniotic band syndrome (ABS), there has yet to be a report of an open meningocele associated with ABS. The patient remained neurologically intact after the repair of his meningocele. His postoperative course was complicated by meningitis with subsequent hydrocephalus necessitating ventriculoperitoneal shunt placement.- - - - - - - - - - ranking = 1keywords = anencephaly (Clic here for more details about this article) |
3/7. prenatal diagnosis of acrania associated with amniotic band syndrome.BACKGROUND: The amniotic band syndrome is a collection of fetal malformations associated with fibrous bands that appear to entrap or entangle various fetal parts in utero and can affect any organ or system and cause a single or multiple anomalies. The anomaly, acrania, is characterized by partial or complete absence of the calvarium with abnormal brain tissue development. literature reports association of amniotic band syndrome and acrania postnatally, but not diagnosed prenatally by ultrasound. CASE: A young woman, gravida 1, para 0, presented for an initial prenatal visit at 35 weeks' gestation and had a first ultrasound that showed a single intrauterine pregnancy at 36 weeks' gestation. This ultrasound also showed polyhydramnios, absence of or a very small cerebrum with either anencephaly or acrania. A targeted ultrasound scan was performed on the following day, which confirmed acrania in view of the fact that we did see an absence of the flat bones of the skull with a substantial amount of abnormal brain tissue present surrounded by a fetal membrane. The patient was counseled, and labor induction was scheduled with a male infant delivered weighing 1763 g after a spontaneous vaginal delivery. The infant was diagnosed with acrania, given supportive care, and died 11 hours later. CONCLUSION: Diagnosis of cranial bone defects can be established by ultrasound in the first trimester of pregnancy. The prenatal diagnosis of acrania associated with amniotic bands by transvaginal ultrasound was visualized in the third trimester in this case; therefore, appropriate counseling and treatment options were offered.- - - - - - - - - - ranking = 1keywords = anencephaly (Clic here for more details about this article) |
4/7. A counseling dilemma involving anencephaly, acrania and amniotic bands.A suggested fetal anencephaly on routine office ultrasound examination resulted in a diagnosis of fetal acrania when targeted ultrasonography was performed by a consultant. Following pregnancy termination, examination of the abortus revealed partial cranial destruction secondary to an amniotic band. It is often difficult to distinguish between anencephaly, acrania, and amniotic band sequence prenatally, but postnatal differentiation is imperative for accurate risk assessment in genetic counseling.- - - - - - - - - - ranking = 6keywords = anencephaly (Clic here for more details about this article) |
5/7. The amniotic band syndrome as a cause of anencephaly. Report of a case.The gross and microscopic features of a 28-week-old stillborn female infant with severe cranial, facial, and cerebral malformations due to amniotic bands are described. The structure of the cerebral remnant is similar to that found in dysraphic anencephaly, but collateral evidence of amniotic band can usually be found. It is important to differentiate between the two conditions, since unlike neural tube defects, anencephaly due to amniotic band does not imply a risk of recurrence in subsequent pregnancies.- - - - - - - - - - ranking = 6keywords = anencephaly (Clic here for more details about this article) |
6/7. Amniotic band disruption syndrome associated with elevated amniotic AFP and normal acetylcholinesterase gel test.ultrasonography in an 18 week pregnancy selected for detailed scanning because of a single elevated maternal serum AFP result suggested the presence of anencephaly. amniocentesis at 19 weeks yielded a clear AF with an elevated AFP result (5.4 MOM) and no evidence of an acetylcholinesterase band of neural origin on PAG electrophoresis. At termination, the fetus had cephalo-amniotic fusion and multiple abnormalities including bilateral cleft lip and palate and digital amputations characteristic of the amniotic band syndrome. The cranial defect was completely sealed by attachment of the amniotic surface of the placenta to the skull.- - - - - - - - - - ranking = 1keywords = anencephaly (Clic here for more details about this article) |
7/7. amniotic band syndrome causing fetal head deformity.amniotic band syndrome is a rare cause of fetal head deformity. We report a case in which antenatal ultrasound in the first half of pregnancy indicated the presence of a fetal cranial deformity, reported as either anencephaly or encephalocele. At assessment autopsy, disruption of the fetal skull was associated with amniotic band formation. Appropriate genetic counselling can be offered to such patients only when detailed pathological examination of the aborted fetus is made. The recurrence rate of amniotic band syndrome does not warrant amniocentesis in a subsequent pregnancy.- - - - - - - - - - ranking = 1keywords = anencephaly (Clic here for more details about this article) |
