# Ulnar Artery Aneurysm Presenting as Raynaud’s Phenomenon: A Case Report

## TL;DR

A hockey player's Raynaud’s-like symptoms were caused by an ulnar artery aneurysm, successfully treated with surgery.

## Contribution

This case report highlights UAA as a rare but treatable cause of Raynaud’s phenomenon in a professional athlete.

## Key findings

- Ulnar artery aneurysm can mimic Raynaud’s phenomenon clinically.
- Surgical excision and end-to-end repair resolved the patient's symptoms.
- Early diagnosis and treatment prevent complications like digital ischemia.

## Abstract

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.
