Abstract

Introduction

Morgagni congenital hernia is an intrathoracic protrusion of the abdominal contents by a congenital retrosternal diaphragmatic defect, caused by fusion disorders of the diaphragmatic transverse septum and chondrocostal arches (Larrey slot), triangular spaces located anteriorly between the diaphragmatic bundles [3,5,11].

There is some confusion about the name of this diaphragmatic hernia, with some authors using the term "Morgagni hernia" for the right hernia and "Larrey hernia" for the left hernia[22]. In the literature this type of congenital diaphragmatic defect can also be found under the name of: Morgagni-Larrey hernias, retro-costo-xiphoid, parasternal, retrochondrosteranal, retrosternal, substernal, etc.[5,22].

Morgagni's hernia is relatively rare, accounting for approximately 3-5% of all types of congenital diaphragmatic hernia. About 90% of this type of hernia occurs on the right, 2% on the left, and in 8% of cases bilateral forms are found. The herniated sac is present in over 95% of cases [7, 10, 25].

The incidence of abnormalities associated with Morgani hernia is about 64%, in 30-40% of patients with Down syndrome, and in 23-44% being found congenital heart malformations[4,7]. Other malformations associated with this type of diaphragmatic defect are: Cantrell's pentalogy, Noonan syndrome, Pradere Willi syndrome, Turner syndrome, intestinal malrotation, anorectal malformations, etc.[4,9,10].
