Replaced right hepatic artery is a well-described normal anatomical variant, not previously associated with acute or chronic abdominal symptoms or long-term sequelae. We report a 15-year-old girl presenting with nearly a decade of symptoms secondary to external compression of the proximal duodenum by the ventral passage of a replaced right hepatic artery. Surgical bypass of the duodenal obstruction significantly improved her symptoms. Replaced right hepatic artery related duodenal compression should be considered in the differential diagnosis of proximal duodenal obstruction. The presence of the replaced right hepatic artery should be clearly communicated to allow optimal presurgical planning.
被替代的右肝动脉是一种描述明确的正常解剖变异，以前与急性或慢性腹部症状或长期后遗症无关。我们报告了一名 15 岁女孩，她因被替代的右肝动脉腹侧通过导致近端十二指肠受压，出现近十年的症状。手术旁路治疗十二指肠梗阻显著改善了她的症状。在诊断近端十二指肠梗阻时，应考虑被替代的右肝动脉相关的十二指肠压迫。应明确告知被替代的右肝动脉的存在，以实现最佳的术前规划。
