    Classification by percentage of diameter reduction (DR) of carotid stent stenosis at 1 month, and 1 year, maximum diameter reduction during surveillance, and diameter reduction at the time of last follow-up, including intervention for >75% DR. CAS, carotid angioplasty and stenting.

  • Image Result
    Freedom from carotid stent stenosis of >50% (triangles) or >75% (squares) diameter reduction (DR) based on duplex ultrasound surveillance using life-table analysis.
