Although liver lacerations are relatively common following blunt trauma, hepatic artery injuries are rare, with only a few cases of hepatic artery dissection caused by blunt trauma reported to date. Due to its rarity, no standardized treatment protocol exists for managing such injuries. We report the case of a 22-year-old female patient referred with a suspected pancreatic injury and liver laceration following blunt trauma. Upon arrival, she presented severe abdominal pain, and a physical examination revealed significant epigastric tenderness. Emergency laparotomy confirmed pancreatic contusion and liver laceration, for which peritoneal irrigation and wide drainage were performed. On postoperative day 17, hepatic artery dissection was incidentally diagnosed with computed tomography, although the patient remained asymptomatic and laboratory tests were within normal limits. Conservative management with an antiplatelet agent was initiated. A follow-up computed tomography scan performed 4 months post trauma demonstrated complete resolution of hepatic artery dissection.
