当院における外傷性副腎損傷の検討

Abstract

Traumatic adrenal injury is quite rare. From January 2008 to March 2018, out of 287 patients with genitourinary trauma, 23 patients (8%) were diagnosed with traumatic adrenal injury at Kobe City Medical Center General Hospital. We retrospectively reviewed the medical records and assessed the traumatic category, image findings and outcome. All 23 patients were bluntly injured. The causes of traumatic adrenal injury were motor vehicle accident (11 patients : 48%) and falls (9 patients : 39%). The majority of injuries occurred on the right side (18 patients : 78%). Associated injuries occurred in all 23 patients, most frequently in the liver (57%) and ribs (57%). Extravasation of contrast materials was identified on computed tomography (CT) in 4 patients (17%). Although 22 patients (96%) were conservatively managed, only 1 patient was treated by transcatherter arterial embolization because of hypotension. One patient died of intraabdominal bleeding. To our knowledge, the present study is the largest on traumatic adrenal injury in Japan.
