The CLEAR-ROAD study: evaluation of a new dual layer micromesh stent system for the carotid artery.


To evaluate the 30-day clinical outcome of Roadsaver carotid stent in non-consecutive subjects at high risk for carotid endarterectomy requiring revascularisation

Study group

  • CLEAR-ROAD is a prospective, multinational, single-arm, IIT
  • 100 non-consecutive patients in 9 centres  (BE, IT and GE) 
  • 31% symptomatic patients


  • Technical success: 100%
  • The 30-day MAE: 2.1% (1 MI -> death / 1 minor stroke - AF)
  • Symptomatic vs Asymptomatic patients – no difference
  • EPD vs no-EPD use – no difference
  • No ISR (>50% DS)

​​Procedural characteristics
​Mean procedural time
​38.7±12.3 min (range 18-72)
​Mean fluoroscopy time
​​9.3±5.0  min (range 0.3-38)
​​Pre-procedural DS
​​85.3±8.0 % (range 55-99)
​​Post-procedural residual stenosis 
​5.2±7.4 % (range 0-40)


The 30-day outcome shows that the Roadsaver stent is a safe and effective device for treatment of subjects at high risk for CEA and can be a valid alternative in both symptomatic and asymptomatic patients.
