Abstract

We report a rare case of a radial artery aneurysm associated with ulnar artery occlusion in an 80-year-old female. Preoperative imaging showed poor visualization of the palmar arch and absent ulnar flow, prompting aneurysmectomy and radial artery reconstruction using a vein graft. Intraoperative findings revealed good retrograde flow, suggesting preserved distal perfusion. This case highlights the importance of accurate preoperative assessment of hand arterial anatomy, particularly the palmar arch, in determining the need for revascularization in radial artery aneurysms with compromised collateral circulation.
