Brief Summary:
Stenting is an alternative to traditional surgery in the treatment of carotid stenosis.The intra and/or postprocedural cerebral embolization remains the most frequent complication. Thanks to the systematic use of cerebral protection systems, these complications have reduced.A debate concerning which cerebral protective device should be more effective is still ongoing.

Condition or disease Intervention/treatment Phase
Carotid Stenosis Device: carotid stenting with MOMA Device: Carotid stenting with filter wire EZ Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 53 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: Randomized Trial of Proximal-versus Distal Cerebral Protection on Micro Embolization During Carotid Artery Stenting in Patients With High Risk Lipid Palque
Study Start Date : February 2009
Actual Primary Completion Date : February 2010
Actual Study Completion Date : February 2010

Arm Intervention/treatment
Active Comparator: carotid stenting with MOMA Device: carotid stenting with MOMA
The MOMA system is an endovascular catheter for proximal protection during carotid stenting. The system allows a concomitant balloon occlusion of both external and common carotid arteries leading to blood flow reversal within the internal carotid artery.
Active Comparator: Carotid stenting with filter wire EZ Device: Carotid stenting with filter wire EZ
The filter wire EZ a distal protection system that is placed in he distal internal carotid artery before carotid stenting. The filter should entrap almost all the debries that are generated during endovascular procedure. At the end of the procedure the filter is retrieved throught a dedicated retrieval catheter.
Other Name: Filterwire EZ - Boston Scientific

Primary Outcome Measures :
  1. number of Microembolization signals (MES) detected with transcranal doppler [ Time Frame: 6 different phases of carotid stenting (lesion wiring; predilation; stent crossing of the lesion; stent deployment; stent post dilation; device tetruieval/deflation ]

Secondary Outcome Measures :
  1. Clinical success [ Time Frame: In hospital and 30 days ]
    Assesment of any clinical and neurological complication (death, any stroke, TIA; myocardial infarction).
