RT Journal Article SR Electronic T1 Traumatic bruising of the hepatoduodenal ligament can conceal a catastrophic injury to the hepatic artery JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e230706 DO 10.1136/bcr-2019-230706 VO 12 IS 9 A1 Adam Daniel Gerrard A1 Raimundas Lunevicius A1 Nicholas Heavey YR 2019 UL http://casereports.bmj.com/content/12/9/e230706.abstract AB We present the case of a 22-year-old man transferred to the regional major trauma centre following a fall of ~15 m. He remained consistently haemodynamically stable for over 10 hours of observation until he deteriorated suddenly with major haemorrhagic shock requiring immediate trauma laparotomy. At laparotomy, 2 L of blood was drained from the abdomen but no source of active bleeding identified. 30 minutes after closure of the abdomen, 500 mL of fresh blood was noted in the drain so he was returned to the theatre where the bleeding source was found to be—after manual compression of a mildly bruised hepatoduodenal ligament—the proper hepatic artery (PHA). This case describes an unusual finding at relaparotomy and shows that even when there is no active bleeding from abdominal organs or classified vessels, it is possible to have isolated injury to PHA.
