-Summary
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.

+Arms and interventions
| Arm | Type | Interventions | Description |
|---|
| Study group | Experimental | Diagnostic Test: Near-infrared spectroscopy and intravascular ultrasound (NIRS-IVUS) | Subjects with carotid stent who consented to undergo near-infrared spectroscopy and intravascular ultrasound imaging. |
- Near-infrared spectroscopy and intravascular ultrasound (NIRS-IVUS) (Diagnostic test): Examination of the extracranial portion of the internal and common carotid artery with pre-existing stent with NIRS-IVUS.
+Outcome measures
Primary outcomes
- Temporal change of lipid core burden index (LCBI) [16 months]: Difference between LCBI (a dimensionless number) within the segment of the carotid artery with implanted stent in the time point of the carotid stenting (baseline LCBI) and in the time point of study intervention (follow-up LCBI). Data from NIRS.
Secondary outcomes
- Late lumen change [16 months]: Difference between luminal volume (mm3) within the segment of the carotid artery with implanted stent in the time point of the carotid stenting (baseline lumen volume) and in the time point of study intervention (follow-up lumen volume). Data from IVUS.
- Late stent expansion [16 months]: Difference between stent volume (mm3) within the segment of the carotid artery with implanted stent in the time point of the carotid stenting (baseline stent volume) and in the time point of study intervention (follow-up stent volume). Data from IVUS.
+Eligibility
Sex: All, ages: 18 Years to any
Inclusion Criteria:
* previous carotid stenting
* data from periprocedural NIRS-IVUS available
* written informed consent
Exclusion Criteria:
* occlusion of the carotid artery on the side of the implanted stent
