副肝动脉瘤破裂出血临床罕见，通过CT血管造影检查（CTA）或多层面重建可为临床诊断提供可靠依据，介入手术是其主要治疗手段。本研究采用介入栓塞成功治疗1例副肝动脉瘤破裂出血病例。该病人副肝动脉变异属于Michels 4型，通过CTA与数字减影血管造影检查明确变异血管出血部位，经介入栓塞治疗后随访，其治疗效果良好。“,”Rupture and bleeding of accessory hepatic aneurysms is clinically rare. Computed tomography angiography (CTA) or multislice reconstruction can provide reliable basis for clinical diagnosis. Interventional surgery is the main treatment method. A successful case of interventional embolization of ruptured accessory hepatic aneurysm in our hospital was reported. The accessory hepatic artery variation of this patient belongs to Michels type 4. The bleeding site of the variant artery was identified by CTA and digital subtraction angiography. Satisfactory results were obtained after interventional embolization and follow-up.
