Arterial aneurysms of the upper limb most commonly involve the ulnar artery at the wrist. Hypothenar hammer syndrome is the usual cause of arterial trauma that forms the aneurysm. After excision of the aneurysm, vein or arterial conduits bridge the arterial gap. Digital ischemia is relieved by arterial reconstruction; however, many patients continue to experience cold-related symptoms.
上肢动脉瘤最常见于腕部的尺动脉。小鱼际锤状指综合征是形成动脉瘤的动脉创伤的常见原因。切除动脉瘤后，静脉或动脉导管桥接动脉间隙。通过动脉重建可缓解手指缺血；然而，许多患者仍会持续出现与寒冷相关的症状。
