Simultaneous repair of Morgagni hernia and ventricular septal defect

Simultaneous repair of diaphragmatic hernia and ventricular septal defect with postoperative complication in a Down syndrome child

Morgagni hernia (MH) is a rare form of congenital diaphragmatic hernia, typically occurring predominantly on the right side and exhibiting a higher prevalence in females. Usually diagnosed incidentally, MH may coexist with congenital heart defects, chest wall abnormalities and certain genetic syndromes such as Down syndrome. A 4-year-old boy with Down syndrome underwent simultaneous repair of MH and closure of a ventricular septal defect (VSD). A vertical midline sternotomy was performed, and the VSD was repaired using the right atrium approach. Subsequently, MH repair was conducted. Three weeks after the surgery, this patient developed a complete heart block, which lead to the implantation of a VVI pacemaker.

Approach to a large rare diaphragmatic hernia in a patient undergoing cardiac surgery

Hernia of Morgagni is an unusual congenital defect of the sternal portion of the diaphragm. Its concurrence with cardiac surgical pathology is rarely described in the literature. Notwithstanding, huge hernia of Morgagni have been noted to cause serious peri-operative impediment and complications. We report the case of a 50-year-old gentleman with a massive Morgagni hernia that threatened strangulation during cardiopulmonary bypass. We describe the combined surgical approach undertaken to repair this hernia, with an accompanying review of the literature relating to misadventure and management of similar large hernia coinciding with cardiac surgery.
