Two cases of ulnar artery aneurysm, with concomitant ulnar nerve compression in the palm are presented. Both followed acute injury and presented with an increasingly painful, warm swelling within 2 weeks of injury. An initial diagnosis of infection was made by experienced clinicians in each case. Ulnar artery aneurysm may be wrongly diagnosed as acute infection. It is suggested that simple excision of the aneurysm and ligation of the ulnar artery is the treatment of choice. Angiography should be reserved for those cases where there is doubt about the diagnosis or adequacy of the collateral circulation. Ulnar nerve deficit may be a result of direct injury rather than a neuropraxia from compression by the aneurysm.
本文报告两例尺动脉动脉瘤病例，均伴有手掌部尺神经受压。两例均有急性损伤史，在损伤后2周内出现疼痛加剧、局部温热肿胀。每例均由经验丰富的临床医生初步诊断为感染。尺动脉动脉瘤可能被误诊为急性感染。建议首选治疗方法为单纯切除动脉瘤并行尺动脉结扎。对于诊断存疑或侧支循环情况不明的病例，应进行血管造影检查。尺神经功能障碍可能是直接损伤所致，而非动脉瘤压迫引起的神经失用。
