Introduction: Adrenal gland injuries (AGI) are seen increasingly frequently owing to advances in modern imaging techniques. This study describes a series of patients with blunt AGI, with the emphasis on AGI as a marker of injury severity, CT-radiographic classification of AGI and associated injury patterns.
Material and methods: A retrospective review of blunt trauma patients with AGI was performed. Variables examined included demographics, mechanism of injury, length of hospital and ICU stay, clinical status on admission, AGI characteristics, associated injuries, complications, procedures, mortality and discharge disposition.
Results: There were 29 AGI patients with a mean injury severity score of 25. The most common injury mechanisms were motor-vehicular collisions (15/29) and falls (5/29). Right-sided AGI (16/29) outnumbered left-sided (12/29) injuries. The most common CT-radiographic types of AGI were adrenal gland contusions and lacerations with limited "blush". While patterns of injuries differed between right and left-sided AGI, the mean number of injuries did not. The most common associated injuries included extremity (21/29), rib (20/29) and spinal fractures (18/29). Common procedures included orthopaedic fixation (10/29), vena cava filter (8/29) and tracheostomy (5/29). A median of two complications per patient was reported, including adrenal insufficiency in two patients. Mortality was 17%. The median hospital and ICU length of stay were 15 and 12 days, respectively.
Conclusions: Adrenal gland injury is associated with significant morbidity and mortality. With modern imaging modalities capable of reliably detecting adrenal injury, the presence of AGI should be considered a marker of overall injury severity. The authors provide a CT-radiographic classification of adrenal injuries.
