Repair of Morgagni hernia and ventricular septal defect through sternotomy

Area of Science:

• Pediatric Surgery
• Congenital Abnormalities
• Cardiothoracic Surgery

Background:

• Morgagni hernias are rare congenital diaphragmatic defects.
• Infants with Down syndrome have a higher incidence of congenital heart defects, including ventricular septal defects.

Observation:

• A male infant diagnosed with Down syndrome presented with a Morgagni hernia and a perimembranous ventricular septal defect.
• The Morgagni hernia occupied the anterior mediastinum and right hemithorax.

Findings:

• Surgical repair involved median sternotomy to address both anomalies.
• The diaphragmatic defect was closed with Prolene mesh, and the hernia sac reinforced the closure.
• The ventricular septal defect was repaired via right atriotomy with a polytetrafluoroethylene patch after cardiopulmonary bypass.

Implications:

• This case highlights the successful simultaneous surgical management of complex congenital anomalies in an infant with Down syndrome.
• It underscores the importance of a multidisciplinary approach in managing neonates with multiple congenital conditions.
• The described surgical technique offers a viable option for complex cases involving both diaphragmatic and cardiac defects.
