Pseudoamniotic band syndrome (PABS) is an iatrogenic complication that causes entanglement of fetal parts in a constrictive sheet of detached or ruptured amniotic membrane after an invasive procedure, namely amniocentesis, amnioreduction or septostomy in twins. The incidence and risk factors for PABS after fetoscopy-guided laser have not been documented [Winer et al.: Am J Obstet Gynecol 2008;1...

Amniotic band syndrome (ABS) is an uncommon congenital malformation characterized by clubfoot deformity, hand and finger anomalies, and cleft lip and palate. In this study, the literature about ABS—possible etiology, treatment protocols, and medical procedures—is discussed. The aim of this study was to evaluate efficiency of nasoalveolar molding therapy for a patient with cleft lip and palate a...

Objective Phocomelia is a rare congenital anomaly seen in 4 million births. Many factors play a role in the etiology of phocomelia such as environmental-genetic factors, teratogen exposure and amniotic band syndrome. Thalidomide, alcohol, cyclophosphamide and retinoic acid have also been implicated in the pathogenesis. Phocomelia may be isolated or accompanied by syndromes. We present a case of...

Amniotic band sequence (ABS) is the term applied to a wide range of congenital anomalies, most typically limb and digital amputations and constriction rings, that occur in association with fibrous bands (1). These alterations may be associated or not with cutaneous and visceral abnormalities. This work, which is a literature review, examines several studies that relate to cases of amniotic band...

Amniotic band syndrome or sequence (ABS) is a fetal congenital malformation, mainly affecting limbs and mostly characterized by digital amputations and constrictions rings due to fibrous amniotic bands (AB). It can also affect the craniofacial area and internal organs. Two main pathological mechanisms have been proposed amnion rupture (exogenous theory) leading to fibrous bands, which wrap up t...

The cause of Congenital Constriction Band Syndrome has been in debate over 300 years. There are two main theories as to what could be its true cause. The two main theories discussed are the intrinsic and extrinsic theories. This condition may cause inhibiting or life-threatening conditions as well as secondary deformities. To correct or help add function to these conditions there are surgical o...

abstract a 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. the cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. the most important physical finding which ...
