Abstract
Background and ObjectiveInformation on the incidence of adrenal trauma and its association with other injuries is limited. Our objective was to study the incidence of adrenal haemorrhage, its association with other injuries, clinical parameters, and long‐term outcomes.Patients and MeasurementsAll patients treated for severe abdominal trauma (Level 1) at Karolinska University Hospital, Solna, between January 1, 2013 and December 31, 2018 were included. Patients with a radiological picture of adrenal haematoma were selected. The injury severity score (ISS) was analysed in the entire cohort. Data were collected from the electronic medical files.ResultsIn total, 1.7% (n = 29/1743) was affected by adrenal trauma. Right adrenal trauma (n = 20/29;69%) was more common than left (n = 6/29;21%, p < 0.01), and 10% were bilateral (n = 3/29). There was no difference in volume in right versus left adrenal trauma [(median 13 (interquartile range (IQR) (7–15) versus 8 (5–13)] ml, p = 0.30). ISS was 23.4 (17–43) in adrenal haematoma patients, higher compared with other trauma patients 16 (8–27) (n = 1714)(p < 0.001).Rib fractures, pneumothorax, and liver lacerations were the three most common findings in association with adrenal trauma. The underlying cause in 48% of the cases was falling from height (≥3 m). Biochemical data demonstrated normal sodium and potassium levels while the lowest haemoglobin level was 72 g/l. At follow‐up, 4 (2–6) years after the trauma, except for three patients who died as in‐patients, all other persons were still living. None seemed to have adrenal insufficiency.ConclusionsAdrenal trauma is rare and does not seem to be associated with clinical features of adrenal insufficiency, even if the bleeding is bilateral.
