Transradial access is a safe approach for visceral endovascular interventions, with lower complication rates compared to transfemoral access. This report describes an unusual case of ulnar artery thrombosis following splenic artery aneurysm embolization via left transradial approach, resulting in non-target digital ischemia and eventual amputation of the ring and little finger distal phalanges. Technical considerations to reduce the incidence of access complications are also reviewed, along with practice modifications undertaken at our institution following this case to improve outcomes.
经桡动脉入路是内脏血管内介入治疗的一种安全方法，与经股动脉入路相比，并发症发生率较低。本报告描述了一例经左桡动脉入路行脾动脉瘤栓塞术后发生尺动脉血栓形成的罕见病例，导致非靶指（环指和小指）末节指骨缺血，最终发生指体截除。本文还回顾了减少入路并发症发生率的技术要点，并介绍了本病例发生后我院为改善治疗结局而进行的操作改进。
