Celiac trunk stenosis can lead to hepatic ischemia and subsequent liver damage. We present the case of an 81-year-old patient with a history of hypertension, ischemic heart disease, hypothyroidism, and biliary lithiasis, who developed hypoxic hepatitis secondary to Dunbar syndrome and a stenosis of the superior mesenteric artery. The patient improved symptoms and liver function tests with conservative management, including intravenous fluids and supportive care. Long-term management involved continued antiplatelet therapy and statins, with consideration of further interventions for celiac trunk stenosis. This case underscores the importance of recognizing Dunbar syndrome as well as superior mesentery trunk stenosis as a potential cause of hypoxic hepatitis. It highlights the need for multidisciplinary management in such cases.展开更多
