摘要

Purpose

This study aimed to assess the endothelialization of drug-eluting stents (DES) 3 months after implantation for the treatment of symptomatic vertebral artery stenosis using endovascular optical coherence tomography (OCT).

Methods

Between March and May 2024, OCT was performed on patients 3 months (90 ± 7 days) after undergoing surgery for stent implantation at the vertebral artery ostium in our center.

Results

Nine DES were implanted in nine patients. The mean follow-up period was 95.6 ± 12.6 days. OCT findings showed the vertebral artery lumen with fully endothelialized stent struts covered by neointima in all nine patients 3 months after implantation, indicating complete endothelialization.

Conclusions

Complete endothelialization of vertebral artery DES occurred 3 months after implantation, providing a theoretical basis for potentially reducing the duration of DAPT 3 months. Further clinical studies are essential to validate these findings.
