Pseudoaneurysm: a rare complication of distal transradial access in the anatomical snuffbox

Abstract

Background: This report presents a case of distal radial artery pseudoaneurysm following cardiac catheterization and its successful endovascular management. Due to its novelty as a catheterization site, few to no reports exist regarding the complications associated with distal radial access. Case presentation: A patient presented to the emergency department with severe wrist and hand swelling 48 h after successful cardiac catheterization via distal radial artery access. Angiography revealed a pseudoaneurysm which was embolized with Onyx™. Post intervention angiogram showed exclusion of the pseudoaneurysm and preservation of the left palmar arch vasculature. Conclusion: The case presented herein demonstrates a rare complication of distal radial access at the anatomical snuffbox.
