Ulnar Artery Aneurysm Presenting as Raynaud's Phenomenon: A Case Report.

Ulnar artery aneurysm (UAA) is an uncommon cause of digital ischemia. It is most often encountered in patients with repetitive injuries to the hypothenar region. UAA can cause significant morbidity, such as pain, nerve compression, and even acute digital ischemia if it is not identified early and treated accordingly. We present a case of a professional hockey player who presented with signs of Raynaud's phenomenon in the right-side ring finger, which was treated with UAA excision and primary end-to-end repair. A brief literature review of the literature is furthermore discussed.
