The primary objective of this study is to evaluate carotid artery stenting (CAS) with and without cerebral protection (CP) to determine if CP improves safety and effectiveness of CAS.
Condition | Intervention |
---|---|
Carotid Artery Stenosis |
Procedure: CAS with/without cerebral protection |
Study Type: | Interventional |
Study Design: | Treatment, Randomized, Open Label, Uncontrolled, Parallel Assignment, Safety/Efficacy Study |
Official Title: | A Randomized Trial of Carotid Artery Stenting With and Without Cerebral Protection |
Estimated Enrollment: | 100 |
Study Start Date: | October 2003 |
Estimated Study Completion Date: | January 2007 |
This study is a single center, prospective, randomized trial evaluating the safety and effectiveness of CAS with and without CP. The study population will be comprised of subjects with atherosclerotic, post endarterectomy restenotic or other obstructive lesions in native carotid arteries. Other carotid artery pathology not amenable to surgical repair (for example carotid artery dissection) will also be considered. Subjects at high risk for complications from standard CEA will be the target population for this study. High risk status will be confirmed by two physicians, one of whom is a vascular surgeon. Both symptomatic and asymptomatic subjects will be enrolled. This will ensure that the proportion of symptomatic subjects is the same in the two arms of the study. “Symptomatic” is defined in the exclusion criteria. The expected duration of this clinical trial is 3 years.
In this study there are there are two arms that a subject may be randomized to:
Group1: CAS with the use of the RX ACCUNET Group 2: CAS without the use of the RX ACCUNET
Ages Eligible for Study: | 18 Years and older |
Genders Eligible for Study: | Both |
Inclusion Criteria:
To participate in this study, the subject MUST have all of the following for inclusion in the study:
The subject should be considered a relatively high risk for carotid endarterectomy. This determination has to be made and documented by two physicians, at least one of who must be a vascular surgeon acting as an investigator on this trial. High risk considerations should include at least one of the following:
Subjects can be either clinically symptomatic or asymptomatic (less than 80 years of age). Symptomatic subjects will have experienced an event within the previous 120 days in the ipsilateral carotid artery distribution. The event will be classified as either 1) one or more TIAs, characterized by distinct focal neurologic dysfunction or monocular blindness with clearing of signs and symptoms within 24 hours, or 2) one or more completed strokes (as defined by this protocol) with persistence of symptoms or signs for more than 24 hours (the most recent event is used as the qualifying event).
Other non-invasive qualifying imaging modalities include:
Computed Tomographic Angiography (CTA) performed at UPMC Presbyterian or Shadyside hospitals.
Exclusion Criteria:
To participate in this study, the subject may NOT HAVE any of the following at enrollment to the study:
