The accordion phenomenon occurs because of mechanical distortion of a straightened vessel during coronary and vascular interventions. To date, however, this phenomenon has not been reported in vessels of the upper abdomen. We therefore describe the accordion phenomenon of the hepatic artery during transarterial chemoembolization seen while treating a liver tumor. As the accordion phenomenon is now known to involve hepatic arteries, it should be differentiated from vascular complications such as vasospasm or intimal injury.
手风琴现象是由于在冠状动脉和血管介入治疗期间,变直的血管发生机械性扭曲所致。然而,迄今为止,上腹部血管尚未报道过这种现象。因此,我们描述了在治疗肝肿瘤时经动脉化疗栓塞过程中肝动脉出现的手风琴现象。由于现在已知手风琴现象涉及肝动脉,所以应将其与血管痉挛或内膜损伤等血管并发症相鉴别。
