True Radial Artery Aneurysm in the Anatomical Snuffbox

Abstract

True radial artery aneurysms are extremely uncommon and those of the distal radial artery are even rarer than those of the proximal radial artery. A review of the literature revealed one case of a true radial artery aneurysm in the anatomical snuffbox and another one distal to the anatomical snuffbox. Those described in literature are usually false aneurysms secondary to direct trauma or iatrogenic. Of a few radial artery aneurysms reported, for some an idiopathic etiology is described and others are atherosclerotic. Here we report an unusual case of a true radial artery aneurysm with idiopathic etiology.
