Pentalogy of Cantrell

Pentalogy of Cantrell is a constellation of five congenital defects that pose a unique challenge for surgeons. Defects of the heart, pericardium, diaphragm, sternum, and anterior abdominal wall are pathognomonic. Although the incidence is low, it is critical to identify it in a timely fashion in order to adequately address all aspects. Early diagnosis, supportive care, and strategic surgical planning with a multidisciplinary team are all key components in managing patients with Pentalogy of Cantrell. In this text we sought to explore the evolution of both the understanding and treatment for this complex entity and provide current recommendations to today's pediatric caregivers.

Prenatal diagnosis and management of omphalocele

Omphalocele (exomphalos) is one of the most common abdominal wall defects. The size of the defect and the severity of the associated anomalies determine the overall morbidity and mortality. Routine prenatal screening and diagnosis of the abdominal wall defect and concurrent anomalies is important as it allows for effective prenatal counseling and optimal perinatal management. The purpose of this article is to discuss the approach to prenatal diagnosis and management of omphalocele.

Fetal MRI in the Identification of a Fetal Ventral Wall Defect Spectrum

Objective  To ascertain if useful criteria for prenatal diagnosis of fetal ventral body wall defects (VBWDs) exists by reviewing published literature on diagnosis of VBWD as compared with our own diagnostic experience. Study Design  A comprehensive literature review of diagnostic criteria of fetal VBWD including pentalogy of Cantrell (POC), omphalocele, exstrophy, imperforate anus, spina bifida (OEIS), cloacal exstrophy, limb-body wall complex (LBWC), and body stalk anomaly was performed followed by a retrospective review of all fetal magnetic resonance imaging (MRI) examinations from our medical center over a 2-year period. Results  Classically, OEIS is omphalocele, bladder exstrophy, imperforate anus, and spina bifida. POC is defects of the supraumbilical abdomen, sternum, diaphragm, pericardium, and heart. LBWC is two of the following: exencephaly or enencephaly with facial clefts, thoracoschisis or abdominoschisis, and limb defects. Twenty-four cases of VBWD on MRI over a 24-month period were identified with seven cases involving defects of additional organ systems. Six of these seven cases demonstrated findings from two or more of the traditional diagnoses POC, OEIS, and LBWC making diagnosis and counseling difficult. Conclusion  There is a lack of consensus on useful diagnostic criteria within the published literature which is reflected in our own diagnostic experience and poses a challenge for accurate prenatal counseling.

Pericardio-Amniotic Shunting for Incomplete Pentalogy of Cantrell

A 27-year-old woman, gravida 2, para 0, presented with an incomplete Pentalogy of Cantrell with an omphalocele, diaphragmatic hernia, and a pericardial defect at 32 weeks' gestation. A large pericardial effusion compressed the lungs and had led to a reduced lung growth with an observed-to-expected total lung volume of 28% as measured by MRI. The effusion disappeared completely after the insertion of a pericardio-amniotic shunt at 33 weeks. After birth, the newborn showed no signs of pulmonary hypoplasia and underwent a surgical correction of the defect. Protracted wound healing and a difficult withdrawal from opioids complicated the neonatal period. The child was discharged on postnatal day 105 in good condition. This case demonstrates that in case of Pentalogy of Cantrell with large pericardial effusion, the perinatal outcome might be improved by pericardio-amniotic shunting.
