Resumo:INTRODUCTION: Pseudoamniotic band syndrome (PABS) occurs iatrogenically after fetal surgery or amniocentesis due to chorioamniotic membrane separation. Separation of the amnion from the chorion can expand to form fibrous amniotic bands that can envelope fetal limbs or the umbilical cord, with consequences ranging from limb constriction to fetal demise. CASE REPORT: We report a case of bilateral fetal pleural effusions at 27 weeks' gestation treated by bilateral thoracoamniotic shunts. Following shunt placement, the hydrothorax resolved. However, chorioamniotic membrane separation developed resulting in PABS with subsequent umbilical cord strangulation and fetal demise at 32 weeks' gestation. CONCLUSION: PABS has been previously described in the literature following various fetal interventions. This is the first reported case of pseudoamniotic band syndrome after placement of fetal thoracoamniotic shunts. A high index of suspicion is required to diagnose PABS via postoperative ultrasound. Post intervention chorioamniotic membrane separation warrants close surveillance for sonographic evidence of PABS.

Resumo: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 (Q79.80) and body wall complex (Q89.7) were reviewed. During the 33-year-study period, there were 153 eligible cases ascertained from 1,411,652 live births and stillbirths, giving a prevalence of 1.08/10,000 total births. There were more males (52%) than females (45%) and 3% were of unknown sex. The average maternal age, birth weight, and gestation was 27 years, 2,701 g, and 35 weeks, respectively. Limb deficiencies occurred in 78% of cases. Amniotic bands with limb deficiency was the most common phenotype (48%). Digital limb deficiency was the most frequent type (56%); however, cases with body wall defects had more severe types of limb deficiencies. The upper limbs only were affected more times (44%), and there was no side preference. Most cases are sporadic but a number of familial occurrences have been reported although some have insufficient documentation and others misdiagnosed. A review of putative risk factors gives conflicting results. © 2016 Wiley Periodicals, Inc.

Resumo:BACKGROUND: A congenital adhesion band is a rare condition, but may induce a small bowel obstruction (SBO) at any age. However, only a few sporadic case reports exit. We aimed to identify the clinical characteristics of congenital adhesion band manifesting a SBO stratified by age group between pediatric and adult patients. METHODS: The medical records of all patients with a SBO between Jan 1, 2009 and Dec 31, 2015 were retrospectively reviewed. Cases associated with previous surgical procedure and cases of secondary obstruction due to inflammatory processes or tumor and other systemic diseases were excluded. The patients were divided into two groups according to age below or above 18 years: pediatric and adult. The basic clinical characteristics were analyzed and compared between groups. RESULTS: Of 251 patients with a SBO, 15 (5.9%) met the inclusion criteria; 10 cases in pediatric group (mean age 17.9 ± 38.7 months) and 5 cases in adult group (mean age 60.0 ± 19.7 years). The pediatric group (66.6%) included 3 neonates, 5 infants, and 2 school children. They usually presented with bilious vomiting (50.0%) and abdominal distention (60.0%), and demonstrated a high rate of early operation (80.0%) and bowel resection (70.0%). In contrast, the adult group (33.3%) presented with abdominal pain (100%) in all cases and underwent a relatively simple procedure of band release using a laparoscopic approach (60%). However, group differences did not reach statistical significance. In addition, two groups did not differ in the time interval to the operation or in the range of the operation (p = 0.089 vs. p = 0.329). No significant correlation was found between the time interval to the operation and the necessity of bowel resection (p = 0.136). There was no mortality in either group. CONCLUSIONS: Congenital adhesion band is a very rare condition with diverse clinical presentations across ages. Unlike adult patients, pediatric patients showed a high proportion of early operation and bowel resection. A good result can be expected with an early diagnosis and prompt management regardless of age.

Resumo: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.

Resumo: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.

Título:Congenital limb deficiencies with vascular etiology: Possible association with maternal thrombophilia.

Resumo: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. We investigated this association through a review of all prenatally identified LDDs at a major tertiary care center in Toronto, Canada over a 12-year period. Our results showed a higher prevalence of thrombophilias among women with a pregnancy affected with an LDD when compared to the general population [χ (3) = 54.63, P < 0.01]. Our research was strengthened by the inclusion of affected pregnancies regardless of outcome, and strict criteria to avoid including LDDs with a non-vascular etiology. Most LDDs were identified during the routine 18-20 week anatomy ultrasound, but some were discovered as early as 13 weeks' gestation. We found an excess of left-sided defects among terminal transverse but not longitudinal deficiencies; additionally, all diagnoses of maternal thrombophilia occurred in the terminal transverse group. Our results support thrombophilia screening in all women with a prenatally diagnosed fetal LDD as well as careful evaluation of the fetal extremities during prenatal ultrasounds in women with a known thrombophilia. © 2016 Wiley Periodicals, Inc.

Resumo:INTRODUCTION: The aims of this study were to evaluate the effects of rapid palatal expansion on the craniofacial skeleton of a patient with unilateral cleft lip and palate (UCLP) and to predict the points of force application for optimal expansion using a 3-dimensional finite element model. METHODS: A 3-dimensional finite element model of the craniofacial complex with UCLP was generated from spiral computed tomographic scans with imaging software (Mimics, version 13.1; Materialise, Leuven, Belgium). This model was imported into the finite element solver (version 12.0; ANSYS, Canonsburg, Pa) to evaluate transverse expansion forces from rapid palatal expansion. Finite element analysis was performed with transverse expansion to achieve 5 mm of anterolateral expansion of the collapsed minor segment to simulate correction of the anterior crossbite in a patient with UCLP. RESULTS: High-stress concentrations were observed at the body of the sphenoid, medial to the orbit, and at the inferior area of the zygomatic process of the maxilla. The craniofacial stress distribution was asymmetric, with higher stress levels on the cleft side. When forces were applied more anteriorly on the collapsed minor segment and more posteriorly on the major segment, there was greater expansion of the anterior region of the minor segment with minimal expansion of the major segment. CONCLUSIONS: The transverse expansion forces from rapid palatal expansion are distributed to the 3 maxillary buttresses. Finite element analysis is an appropriate tool to study and predict the points of force application for better controlled expansion in patients with UCLP.

Resumo:BACKGROUND: The purpose of this study was to determine the feasibility of single-stage resection for type II congenital constriction rings by means of histologic examination of resected specimens and imaging examination of affected extremities, and to evaluate the appearance and function of the extremities after single-stage surgery. METHODS: The features of the skin on the constriction rings and the subcutaneous tissues were identified through continuous sectioning, hematoxylin and eosin staining, and immunohistologic staining of specimens of type II constriction rings obtained by means of surgery. The relationship between the constriction rings and the deep main blood vessels was evaluated using magnetic resonance imaging. Single-stage resection of the constriction band, reduction of the fascial flap, and triangular flap-plasty were performed for 21 patients. The appearance, lymphedema, and movement of the extremities were compared before and after the operation. RESULTS: Type II constriction rings in the extremities had normal full-layer skin structures. Collagen was found deposited densely at the base of the grooves, but the normal subcutaneous tissue space remained, and the vital nerves and blood vessels were unaffected. Complete resection of the constriction rings was achieved in all 21 patients, and lymphedema subsided 2 months after the operation. No episode of recurrence was found, and limb function was not affected at 26-month follow-up. CONCLUSIONS: Type II congenital constriction rings in limbs possess normal subcutaneous tissue spaces. A single-stage operation, which includes complete resection of the rings, fascial flap reduction, and triangular flap-plasty, could achieve a satisfactory appearance and good function. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
