Pseudoaneurysm: a late complication of the transradial approach after coronary angiography.

Percutaneous interventional procedures via the radial artery are now commonplace and associated with minimal risks. The favorable anatomic relations of the radial artery to the surrounding structures determine the safety of this approach. The absence of major nerves and veins in the vicinity of the radial artery makes the likelihood of arteriovenous fistulas extremely small. We report a case of pseudoaneurysm of the radial artery, which was only clinically recognized three months after coronary angiography.
