Idiopathic True Aneurysm of the Radial Artery: A Rare Entity

Introduction

True aneurysms of the radial artery are extremely rare. Most cases of Radial artery aneurysm are the result of iatrogenic trauma, however other rare causes such as vascular tumours, connective tissue diseases and occupational injury have also been reported.

Case report

A 60-year-old man presented with a pulsating mass in the anatomical snuffbox of the left hand. He underwent distal radial artery ligation and excision of the aneurysm. Histopathology demonstrated this to be a true aneurysm in continuation with the vessel wall.

Discussion

There are only a few cases of true distal radial artery aneurysm described in the literature. Careful examination and pre-operative imaging will help determine the most appropriate surgical management, including the need for vascular reconstruction.
