Delayed Presentation of a Traumatic Radial Artery Pseudoaneurysm

Introduction & Objective Radial artery pseudoaneurysms are rare and almost exclusively iatrogenic in origin. Post- traumatic radial artery pseudoaneurysms are even more uncommon, and relevant literature is limited to few case reports which mainly describe an acute presentation and management via external compression, thrombin injection, resection and bypass graft, or radial artery ligation. This case describes a rare diagnosis of traumatic radial artery pseudoaneurysm with a delayed presentation and successful resection with primary end-to-end anastomosis.

Radial artery pseudoaneurysms can carry significant morbidity including compartment syndrome, critical limb ischemia, and digital necrosis. Providers performing trans-radial procedures should maintain a high index of suspicion for this complication to avoid compromise of functional status and optimize patient outcomes.
