Rev Colomb Obstet Ginecol [online]. ISSN Objective: To report a Pentalogy of Cantrell case associated with acrania, medial facial cleft and reduction of the right limbs as a result of amniotic bands; and to conduct a review of the literature on the pathogenesis of amniotic bands and the findings of the reported case. Materials and methods: Case report of a demised neonate with the above mentionated congenital malformations born to a 15 year-old primigravida in her 34 weeks of gestation who came to Hospital Universitario del Valle HUV , a level III and IV referral hospital for obstetrics belonging to the public network in south-western Colombia. The clinical record, photographs of the neonate and X-Ray images were used as the sources of information. A search in the literature was conducted using the terms "Pentalogy of Cantrell and amniotic band syndrome", "Limb body wall complex and amniotic band syndrome" through PubMed in the Medline databases in English and Spanish, with no time limitation; the search included case reports, topic reviews and case series.

ISSN The amniotic band syndrome ABS is characterized by accumulation of fibrous tissue bands or strings that adhere to the fetus and may produce compression in different sites.
Most cases present multiple congenital anomalies incompatible with life. A small group of fetuses have isolated constrictions of the limb that may cause severe limb dysfunction or limb amputation if not treated during pregnancy. This rare condition occurs in approximately to live births. The exact cause of ABS remains uncertain; however, theories of intrinsic, extrinsic and iatrogenic reasons have been proposed.
The evolution of the limb affected by ABS is characterized by progression of distal edema due to venous obstruction, and intrauterine amputation of the limb from vascular insufficiency. Fetoscopic release of the amniotic bands through minimally invasive surgery techniques may allow life preservation as well as limb function.

Amniotic bands sequence is a congenital disorder characterized by craniofacial, body wall, and limb anomalies that may be associated with fetalplacental fibrous bands. Its prevalence has been reported to range from 0. Different theories have attempted to explain the etiology of amniotic band sequence; however, none has individually been able to support each and every defect observed, so it has been considered to be a multifactorial condition. The pre- and post-natal identification of anomalies suggestive of amniotic band sequence is useful for the diagnostic approach and implementation of timely therapeutic interventions favoring the release of the amniotic bands using fetoscopy with recovery of the involved distal limb perfusion, or else the possibility of performing a post-natal surgical repair. It is also helpful to provide genetic counseling. This article offers an update on the epidemiological aspects, etiological theories, risk factors, clinical characteristics, diagnosis including antenatal diagnosis , genetic counseling, therapeutic approach, and prognosis of amniotic bands sequence.
