True aneurysms of the digital artery are very rare. Only 13 cases, caused by chronic trauma from occupational or sports-related overuse, have been reported. We present the first case of a true aneurysm of the digital artery of the left ring finger caused by chronic repetitive trauma from a wedding ring. The patient was a 44-year-old teacher who presented with a 1.5-cm subcutaneous mass on the radial aspect of the proximal phalanx of the finger, just proximal to the proximal interphalangeal joint. Exploration of the mass revealed a 1-cm aneurysm continuous with the radial digital artery. The aneurysm was excised and the proximal and distal ends of the radial digital artery ligated. Microscopic examination of the excised specimen confirmed the diagnosis of a true aneurysm with the lumen filled with an organising thrombus. The patient had an uneventful recovery with good wound healing, intact sensation, and normal capillary return.
指动脉真性动脉瘤非常罕见。仅报道过13例，病因是职业或运动相关过度使用导致的慢性创伤。我们报告首例因婚戒慢性重复性创伤引起的左手环指指动脉真性动脉瘤病例。患者为一名44岁教师，在手指近节指骨桡侧、近端指间关节近端出现一个1.5厘米的皮下肿物。对肿物进行探查发现一个1厘米的动脉瘤，与桡侧指动脉相连。切除动脉瘤并结扎桡侧指动脉的近端和远端。对切除标本进行显微镜检查，证实为真性动脉瘤，管腔内充满机化血栓。患者恢复顺利，伤口愈合良好，感觉正常，毛细血管回流正常。
