Ultrasonographic features of seven patients with diaphragmatic rupture
due to blunt trauma were analyzed. The ruptures occurred at the left
hemidiaphragm in four patients and at the right in three. Direct ultra
sonographic findings were as follows: disrupted diaphragm in four pati
ents; nonvisualized diaphragm in three patients; floating diaphragm in
two patients; and herniation of the liver or bowel loops through the
diaphragmatic defect in three patients. Indirect sonographic findings
included pleural effusion or subphrenic fluid collection in five patie
nts and splenic laceration in one. Although the number of patients was
limited, ultrasonography was very useful for the diagnosis of diaphra
gmatic rupture.
