Radial artery pseudoaneurysm at the previous site of invasive monitoring

Abstract

This report presents a case of left radial artery pseudoaneurysm developing at the previous site of invasive monitoring. The patient had prosthetic mitral valve replacement one month earlier, and anti-coagulation therapy had started on the first post-operative day. The patient's radial artery aneurysm with a 4-centimeter diameter was resected and the radial artery was ligated.
