Amniotic band

Sarah M Holmen, Tiki Bakhshi, Maria M Molina, Larissa F Weir
BACKGROUND: Chorioamniotic membrane separation (CMS) is a rare finding that is commonly preceded by invasive fetal procedures. The presence of CMS can also be associated with uncommon maternal or fetal conditions as well as preterm delivery, amniotic band syndrome, umbilical cord complications, and fetal and neonatal death. It is classified as a high-risk antepartum condition due to the significant fetal morbidity and mortality that may ensue. CASE REPORT: A 40-year-old gravida 5 para 1212 at 35 weeks presented for antepartum fetal testing...

Congenital constriction of the limbs is usually due to amniotic band syndrome, which often causes damage to the skin and soft tissues. We report an unusual case in which a neonate had recent fractures of both leg bones with an amniotic band encircling the limb. Non-operative treatment was successful. Challenges to the management of neonatal limb constriction include the absence of a consensus about the best treatment and the high frequency of damage to vessels and nerves.

Prevalence rates of amnion rupture sequence, limb body wall defect, and body wall defects vary widely. Comparisons are difficult due to small case numbers and the lack of agreement of definition, classification, and pathogenesis. This study reports the prevalence of cases classified in five distinct categories. The Alberta Congenital Anomalies Surveillance System data on live births, stillbirths, and terminations of pregnancy (<20 weeks gestation) occurring between 1980 through 2012 with the ICD-10 Royal College of Paediatrics and Child Health Adaptation codes used for congenital constriction bands (Q79...

Body stalk anomaly (BSA) and amniotic band syndrome (ABS) are rare similar fetal sporadic polymalformative syndromes of unknown etiology, though there are certain differences between them. BSA is a combination of developmental abnormalities involving neural tube, body wall, and the limbs with persistent extra embryonic coelomic cavity. ABS is characterized by the presence of thin membrane-like strands attached to fetal body parts and causing constrictions and amputations. This is a cohort study involving 32,100 patients who were referred for routine antenatal ultrasound scan...

Malformations and deformations of the forefoot are a frequent reason for consultation. The most frequent malformations viewed at birth are syndactylies (second web space), clinodactylies (quintus varus, halllux), polydactylies (hallux, fifth toe). The macrodactylies, hypoplasia, amniotic bands are rare. The management of these defects requires knowledge of surgery adult foot, plastic surgery and especially collaboration with physiotherapists, podiatrists and orthotists. The fast growth of the foot the first year and the development of walking at one year require to start early the treatment of deformations and to anticipate the evolution of malformations...

Congenital limb deficiency defects (LDDs) are etiologically heterogeneous. Acquired causes include amniotic bands, teratogens exposure, and chorionic villus sampling before 10 weeks' gestation and intrinsic causes include single-gene disorders and chromosome abnormalities. However, a substantial number of cases, especially terminal transverse deficiency defects, occur without an obvious cause and are ascribed to vascular disruption events. Some studies have found an association between maternal thrombophilia and congenital LDDs...

INTRODUCTION: The incidence of facial cleft is rare and ranges between 1.43 and 4.85 per 100,000 births. To date, there have been few reports of detailed ophthalmologic examinations performed in cases of facial cleft. Here, we report a case of optic-nerve hypoplasia and anterior segment abnormality associated with facial cleft. CASE REPORT: A 9-day-old female infant was delivered by cesarian section at 34 weeks of gestational age (the second baby of twins) and weighed 2,276 g upon presentation...

BACKGROUND: While associations between secondhand smoke and a few birth defects (namely, oral clefts and neural tube defects) have been noted in the scientific literature, to our knowledge, there is no single or comprehensive source of population-based information on its associations with a range of birth defects among nonsmoking mothers. OBJECTIVE: We utilized data from the National Birth Defects Prevention Study, a large population-based multisite case-control study, to examine associations between maternal reports of periconceptional exposure to secondhand smoke in the household or workplace/school and major birth defects...

Amniotic membrane (AM) due to its anti-inflammatory, anti-scarring and anti-angiogenic properties is used as corneal and wound grafts. When developing AM tissue banks, cell viability, membrane morphology and genomic stability should be preserved following cryopreservation. To analyze the changes rendered to the AM during the process of cryopreservation by comparing different combinations of standard cryopreservation media; fetal bovine serum (FBS), dimethyl sulfoxide (DMSO), Dulbecco's modified eagle's medium (DMEM) and glycerol at -80 °C and at -196 °C for a period of 6 weeks and at 4 °C in 70 % alcohol for 6 weeks...

Turtle karyotypes are highly conserved compared to other vertebrates; yet, variation in diploid number (2n = 26-68) reflects profound genomic reorganization, which correlates with evolutionary turnovers in sex determination. We evaluate the published literature and newly collected comparative cytogenetic data (G- and C-banding, 18S-NOR, and telomere-FISH mapping) from 13 species spanning 2n = 28-68 to revisit turtle genome evolution and sex determination. Interstitial telomeric sites were detected in multiple lineages that underwent diploid number and sex determination turnovers, suggesting chromosomal rearrangements...

Introduction Fetoscopic release of amniotic bands has proved its life- and limb-saving potential. Rupture of the amnion and separation of chorion from the amnion and uterine wall can however preclude the standard fetoscopic approach to release the amniotic bands using a single port. Methods and Materials A 28-year-old G1P0 woman was referred to our unit at 19 weeks due to amniotic band syndrome involving the left ankle, the infrapatellar region of the right leg, and the umbilical cord. Of note, part of the fetus was seen outside the amniotic cavity by ultrasonography and the left ankle and foot were severely swollen...

We report a case of amniotic band syndrome diagnosed prenatally by serial sonographic examinations. Our initial sonographic image showed a large fetal nuchal translucency (NT) at 12 weeks' gestation. Repeated fetal ultrasound images revealed an amniotic band and right upper limb anomaly. Fetal MRI at 19 weeks' gestation revealed right forearm hypoplasia and pseudosyndactyly. The fetus was prenatally diagnosed with amniotic band syndrome and was suspected of having severe functional impairment of the deformed limb...

We present two cases of fetal acrania/exencephaly reconstructed employing the three- (3D) and four-dimensional (4D) HDlive rendering mode in early gestation. Two fetuses with acrania/exencephaly were studied with the 3D/4D HDlive rendering mode at 13 and 15 weeks, respectively. In Case 1, at 13 weeks' gestation, deformed and degenerated brain tissues were clearly shown using the 3D/4D HDlive rendering mode. In Case 2, at 15 weeks and 6 days of gestation, two amniotic bands and acrania/exencephaly were depicted with the 3D/4D HDlive rendering mode...

Amniotic band can cause a broad spectrum of anomalies ranging from simple band constrictions to major craniofacial and visceral defects. It can cause significant neonatal morbidity. Accurate diagnosis will help in the management of the present pregnancy and in counseling with regard to future pregnancies. Here we report three cases of amniotic band syndrome detected in the prenatal period.

The Tessier number 3 cleft is rare. In this paper, we report two extremely rare cases of simultaneous Tessier number 3 cleft, contralateral cleft lip, and signs of amniotic band syndrome. In the two cases, we confirmed that amniotic bands were the probable cause of the Tessier number 3 cleft, where swallowed fibrous strands of amniotic bands entangle a typical cleft lip and cause the more severe Tessier number 3 cleft. In this study, Z-plasty was performed for one case, and a straight-line method was used for the other...

OBJECTIVE: The objective of this study was to determine whether puncturing the uterine wall and the amnion causes uterine contractions that result in fetal abnormalities. MATERIALS AND METHODS: An experimental study was performed using four groups of three female rabbits. Group A received a puncture of the amniotic membranes of one of the uteri on day 15 of gestation followed by group B on day 16, group C on day 17, and group D on day 18. The duration and force of contractions and fetal abnormalities were determined...

Amniotic band syndrome is a rare congenital disorder. The authors report the first cases documented at Souro Sanou University Hospital in Bobo-Dioulasso (CHUSS) in 2 male new borns. The malformations found at birth, were worn only on limbs and were in the form of skin furrow necking with a major lymphedema downstream. In both cases, the constriction furrow at member pelvic was associated with a club foot and a pseudosyndactyly in one case. Surgical treatment consisted of a section of the constrictor ring and a Z-plasty...
