Amniotic rupture sequence (ARS) is a disruption sequence presenting with fibrous bands, possibly emerging as a result of amniotic tear in the first trimester of gestation. Our comparative study aims to assess whether there is a difference in the clinical pattern of congenital limb and internal organ anomalies between ARS with body wall defect (ARS-BWD) and ARS without BWD (ARS-L).
Among 1,706,639 births recorded between 1998 and 2006, 50 infants with a diagnosis of ARS were reported to the Polish Registry of Congenital Malformations. The information on 3 infants was incomplete, thus only 47 cases were analyzed. These infants were classified into groups of ARS-L (38 infants) and ARS-BWD (9 infants).
The ARS-BWD cases were more frequently affected by various congenital defects (overall p < 0.0001), and in particular by urogenital malformations (p = 0.003). In both groups, limb reduction defects occurred in approximately 80% of cases; however, minor and distal limb defects (phalangeal or digital amputation, pseudosyndactyly, constriction rings) predominated in the ARS-L group (p = 0.0008). The ARS-L group also had a higher frequency of hand and upper limb involvement.
This observation suggests that amniotic band adhesion in ARS-L takes place at a later development stage. Although limited by a small sample size, our study contributes to the growing evidence that both ARS entities represent two nosologically distinct conditions.
羊膜破裂序列征(ARS)是一种以纤维束带为特征的破坏序列征,可能由于妊娠早期羊膜撕裂所致。我们的对比研究旨在评估合并体壁缺损的羊膜破裂序列征(ARS-BWD)与不合并体壁缺损的羊膜破裂序列征(ARS-L)在先天性肢体和内脏器官畸形临床模式上是否存在差异。
在1998年至2006年记录的1,706,639例出生病例中,有50例诊断为ARS的婴儿被报告至波兰先天性畸形登记处。3例婴儿的信息不完整,因此仅分析了47例病例。这些婴儿被分为ARS-L组(38例婴儿)和ARS-BWD组(9例婴儿)。
ARS-BWD病例更常受到各种先天性缺陷的影响(总体p<0.0001),尤其是泌尿生殖系统畸形(p = 0.003)。在两组中,约80%的病例出现肢体减少缺陷;然而,ARS-L组以轻微和远端肢体缺陷(指骨或手指截肢、假性并指、缩窄环)为主(p = 0.0008)。ARS-L组手部和上肢受累的频率也更高。
该观察结果表明,ARS-L中的羊膜带粘连发生在发育后期。尽管受样本量小的限制,但我们的研究有助于越来越多的证据表明这两种ARS实体代表两种不同的疾病状态。
