Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The 'Long-term Follow-up Near-infrared Spectroscopy and Intravascular Ultrasound Imaging of Internal Carotid Artery Stenosis Treated With Stenting' trial is an academic research project. It follows already published results of a research on carotid plaque composition in patients undergoing carotid stenting.

Patients who were treated with carotid stenting will be invited to participate on the trial. The written informed consent will be needed. The participants will undergo carotid angiography, intravascular near-infrared spectroscopy and intravascular ultrasound of the extracranial portion of the internal and common carotid artery with implanted stent.

The aim of the trial is to describe long-term change of the luminal and stent dimensions, vessel wall remodeling and plaque composition after carotid stenting. The findings will help to understand the long-term effect of carotid stenting on the carotid stenosis and mechanisms of plaque stabilization - sealing with stent.
