Fragments of hydrophilic polymer coating as an embolic material - rare complication and potential cause of death. / Fragmenty hydrofilowych powlok polimerowych jako material zatorowy ­ rzadkie powiklanie i potencjalna przyczyna zgonu.

The most common complications of percutaneous coronary interventions and other endovascular procedures include minor hemorrhage, hematoma, or infection at the insertion site [1]. Much more serious ones include damage to the vessel wall, dissection, shock from contrast administration, acute kidney injury, myocardial infarction [2] and ischemic stroke [3]. Ischemic complications can be caused by an embolic incident due to a thrombus formation or detachment of atherosclerotic plaque fragments [3]. A rarely diagnosed complication is ischemia caused by microembolisms from the material covering the equipment inserted into the vessel - hydrophilic polymer coating (HPC)[4]. We present an interesting case of HPC revealed in coronary vessels within myocardial preparations taken in forensic post-mortem examination conducted at the Department of Forensic Medicine in Bydgoszcz (L.dz. 676/19). This article raises the issue of clinical implications and forensic aspects.
