Complete Pentalogy Of Cantrell: Case Report And Review Of Literature

Abstract

Introduction: Pentalogy of Cantrell (POC) is a rare congenital anomaly with two sub-categories: complete or partial. Complete has all five defects (anterior diaphragmatic defect, ventral abdominal wall defect, pericardial defect, intracardiac anomalies, and lower sternal defect). The first documented case was described by Cantrell et al. in 1958. Both sporadic and genetic causes have been proposed for POC, with a reported incidence of 5 - 10 cases per one million live births and various clinical presentations. The prognosis of POC depends on the severity of the defects and the associated cardiac anomalies. This case report seeks to increase awareness of this condition, emphasize the need for appropriate counselling in our environment, and review the literature on previous reported cases’ outcomes. Case Presentation: A 5-hour-old term female neonate was referred to our Children Emergency Center with multiple defects (ectopia cordis, sternal cleft, omphalocele, and limb abnormalities) with dysmorphic facies. A diagnosis of POC was made, and multidisciplinary management was instituted. The eviscerated heart and epigastric omphalocele were dressed and evaluated for palliative surgical care. However, she developed complications with sepsis and electrolyte derangements and died from multi-organ failure before any surgical intervention could be carried out. Conclusion: Though rare, the Pentalogy of Cantrell in its classical form does occur in our environment. The presence of extracardiac and limb deformities worsens the outcome. Based on poor outcomes, there is a need to emphasize appropriate antenatal and postnatal assessments to provide effective counselling on termination, neonatal palliative care, and surgical repairs as appropriate.
