A Case of Acute Superior Mesenteric Artery Embolism with Severe Ischemic Liver Injury Successfully Treated by Endovascular Treatment

We describe an interesting clinical course of a patient who developed severe ischemic liver injury due to acute embolism of the superior mesenteric artery (SMA) and celiac artery. A 70-year-old man was hospitalized for abdominal pain and diarrhea. Abdominal computed tomography demonstrated a variant common hepatic artery arising from the SMA and multiple thromboembolic occlusions of visceral arteries, including the SMA and celiac artery. Laboratory data showed markedly elevated hepatic enzymes, which increased after admission despite the initiation of systemic anticoagulant and thrombolytic therapy. The patient was successfully treated by endovascular recanalization of the SMA occlusion via transcatheter embolus aspiration, thrombolysis, balloon angioplasty, and stent placement. Severe ischemic liver injury may occur in the setting of synchronous embolism of the SMA and celiac artery, and these phenomena may have a critical impact on the choice of treatment strategies and prognosis. Endovascular treatment appears to an effective treatment option.
