Pseudoaneurysm of the Radial Artery After CMC Arthroplasty.

Pseudoaneurysm of the radial artery is an unusual condition. Most radial artery pseudoaneurysms occur as a result of catheterization; however, any traumatic event that damages the vessel can lead to a symptomatic pseudoaneurysm. This report presents a case of an unusual late presentation of clinical symptoms associated with a pseudoaneurysm of the radial artery after arthroplasty of the thumb carpometacarpal joint.
