Radial Artery Pseudoaneurysm Following Cardiac Catheterization: A Case Report.

The transradial approach is the most preferred method for cardiac catheterization. The radial route approach has many advantages, including fewer puncture site-related complications and early mobility and discharge. The vascular complications include radial artery spasms, occlusions, dissections, perforations, and compartment syndrome. Although pseudoaneurysms are a well-known complication of femoral access (0.2%-3%), pseudoaneurysms are very infrequent (0.05%) after radial artery access. Very few cases of radial pseudoaneurysms have been reported to date. We present a rare case of an 82-year-old man on dual antiplatelet and anticoagulant therapy who underwent coronary angiography via the radial route. The patient developed a pseudoaneurysm requiring surgical intervention.
