Diaphragmatic rupture: a frequently missed injury in blunt thoracoabdominal trauma patients

摘要

In the US and Western Europe, trauma is the fourth most common cause of death and the leading cause of death in the population less than 45 years of age [Mullinix and Foley, J Comput Assist Tomogr 28(Suppl 1):S20–S27, 2004]. Diaphragmatic injuries occur in 0.8 to 8% of patients after blunt trauma (Gray H, The muscles of the thorax. Anatomy of the human body. Lea & Febiger, Philadelphia, 1918) and may be a predictor of severity of injury in the blunt trauma patient [Worthy et al., Radiology 194(3):885–888, 1995]. The clinical diagnosis of diaphragmatic rupture (DR) is difficult and is missed in anywhere from 7 to 66% of patients [Cantwell, Radiology 238(2):752–753, 2006]. The accurate diagnosis and prognosis of this pathology depend on a complete knowledge of the clinical and radiological presentation. Computed tomography is the imaging modality of choice in the assessment of patients with clinical or radiographic findings suggestive of DR.
