Ulnar artery aneurysm is very rare in infancy. Only a few reports have been done. We report an 8-month-old baby with true ulnar artery aneurysm on her hypothenar eminence. She had no specific past medical history, but an episode of falling. We resected the pulsating mass compressing the ulnar nerve, utilizing a surgical microscope. Reconstruction of the vascular deficit was not performed. She presented no functional deficit of the hand and no evidence of growth disturbance so far. As hypothenar eminence is a susceptible part for repetitive strikes, and as vein is fragile to the pressure, bypassing arterial route with vein graft is not recommended unless there is no other option.
尺动脉动脉瘤在婴儿期非常罕见。仅有少数病例报告。我们报告一例8个月大的婴儿，其小鱼际隆起处存在真性尺动脉动脉瘤。她既往无特殊病史，仅有一次摔倒经历。我们在手术显微镜下切除了压迫尺神经的搏动性肿块。未进行血管缺损重建。目前她手部无功能缺损，也没有生长发育障碍的迹象。由于小鱼际隆起是易受反复撞击的部位，且静脉对压力较为脆弱，除非别无选择，否则不建议使用静脉移植物绕过动脉路径。
