A Newly Developed Stent Thrombus Related to Optical Coherence Tomography

Abstract

Optical coherence tomography (OCT) is a useful coronary imaging tool for atherosclerotic plaque characterization and stent evaluation. However, proximal balloon inflation is required in order to reduce signal changes caused by red blood cells and to acquire a clear image. One rare acute complication related to proximal balloon occlusion is micro-thrombus formation. We report a case of multiple, acute micro-thrombi forming after an OCT procedure, despite the use of appropriate prevention for intracoronary thrombus formation.
