Reconstruction for Ulnar Artery Aneurysm at the Wrist

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.
