Design: Prospective, multicenter, single-arm study with an extended follow-up period.

Sample Size: 204 participants (based on the final number of cases enrolled in the registration trial).

Endpoints:

Primary: Surgical success rate (residual stenosis \<30% after stenting). Secondary: Target lesion re-narrowing rate, target lesion revascularization rate, MAE rate, ipsilateral stroke rate, and MACCE rate at 3 and 6 months postoperatively.

Follow-Up: Participants will be followed up at 3 months ±15 days and 6 months ±30 days postoperatively.

Inclusion criteria:

All patients participating in this extended follow-up period are sourced from the registered clinical trial.
