Clinical characteristics of adrenal gland trauma

Abstract

To explore the clinical characteristics of adrenal gland trauma. A retrospective review was performed for 17 patients presenting with adrenal gland injury diagnosed by computed tomography (CT). There were 11 males and 6 females with an average age of 14-60 (38 ± 12) years. The injuries occurred as the consequence of motor vehicle crash (n = 13) and secondarily to a fall (n = 4). The average time from accident to admission was 5.0 ± 4.1 hours and the average injury severity score (ISS) 31.5 ± 10.3. Among 9 patients with throat injuries, there were pulmonary contusion, hematopneumothrax and rib fracture, followed by extremity fracture (n = 8) and pelvis fracture (n = 7). Additionally, 3 patients had injuries to vertebral column and 4 suffered closed cranial injury. There were 3 patients with liver injury, including subcapsular hematoma (n = 2) and laceration (n = 1). The urinary related injuries included renal contusion and laceration (n = 5) and urethral injury (n = 1). Among them, 15 had injuries to right adrenal glands and 2 to left ones. The CT findings of adrenal trauma were adrenal contusion and focal hematoma. All patients received conservative treatment. No patient died. The complications of urinary tract infection (n = 6) , deep vein thrombosis (n = 3), pneumonia (n = 3) and gastrointestinal ulceration (n = 2) improved with conservative treatment.Vital signs were all stable after 1 week treatment except for 1 patient operated for intracranial hematoma. The average follow-up period was 2.0- 12.0 (5.5 ± 2.7) weeks for 11 patients. The re-examination of CT showed a absorption of hematoma. And 2 cases had a complete absorption. Adrenal gland injury is rare and there is a right-sided preponderance.It is associated with high injury severity.For a lack of obvious clinical manifestations, missed diagnosis is frequently made. CT scan is the first-choice diagnostic tool for adrenal gland injury. Conservative treatment is often satisfactory and hormonal supplement unnecessary.
