The natural history of unrecognized diaphragmatic hernias after blunt trauma: A narrative review and presentation of three clinical cases

Abstract

A diaphragmatic hernia may be the consequence of a blunt traumatic diaphragm rupture, representing a frequently misunderstood post-traumatic complication. Although it is uncommon, it may be associated with high morbidity and mortality when diagnosed late. An extensive review was conducted using the PubMed/MEDLINE (National Library of Medicine, Bethesda, USA) database for articles published in the English language. Three very interesting clinical cases are presented to demonstrate the clinical aspects of the reviewed evidence. They can show how the misrecognition of a left diaphragmatic rupture after a closed trauma can cause serious complications. Tension viscerothorax associated with hemodynamic shock is an example, which represents both an extremely rare and life-threatening complication.
