Aneurysm of the Radial Artery in the Anatomical Snuff Box

Abstract

Aneurysms of the radial artery are uncommon; most of the recorded cases occurred after trauma. We report a case of true aneurysm of radial artery in the anatomical snuff box in a 63-year-old healthy non-smoking woman with no history of trauma. The Duplex scan and the MRA confirmed the presence of the aneurysm of the distal radial artery, approximately 1.1 by 1.0cm. We checked the patency of the palmar collateral circle by a preoperative and intraoperative Allen's test with a hand held Doppler. We ligated the radial artery and excised the aneurysm. The histopathologic study showed a non-specific aneurysm without specific alterations, excluding atherosclerotic or micotic nature.
