Vascular anomalies of the celiac trunk and its branches are rare but carry significant diagnostic and surgical implications. We report a case of a 24-year-old male presenting with acute abdominal pain and vomiting. Contrast-enhanced CT revealed a hypoplastic celiac trunk with aberrant hepatic and splenic arteries arising from the superior mesenteric artery (SMA), a configuration distinct from the more commonly described replaced right hepatic artery. Associated findings included dilated duodenum and jejunum with wall thickening and mesenteric inflammation, likely reflecting altered mesenteric hemodynamics. The patient was managed conservatively for an acute abdomen with suspected transient vascular congestion. This rare vascular variant highlights the importance of CT angiography in identifying atypical anatomy, which is crucial for preventing misdiagnosis and guiding safe surgical or interventional procedures.
腹腔干及其分支的血管异常罕见，但具有重要的诊断和手术意义。我们报告一例24岁男性，表现为急性腹痛和呕吐。增强CT显示腹腔干发育不全，肝动脉和脾动脉异常起源于肠系膜上动脉（SMA），这种构型不同于更常见的替代右肝动脉。相关表现包括十二指肠和空肠扩张，肠壁增厚和肠系膜炎症，可能反映了肠系膜血流动力学改变。该患者因怀疑短暂性血管充血导致的急腹症接受了保守治疗。这种罕见的血管变异突出了CT血管造影在识别非典型解剖结构方面的重要性，这对于防止误诊和指导安全的手术或介入操作至关重要。
