  Purpose

Carotid Endarterectomy (CEA), surgical removal of the blockage in the neck artery, is the accepted management of choice for significant blockage of the carotid artery. Previous studies showed improved perioperative outcomes and prevention of recurrent blockage by the use of the patch to close the surgical incision in the artery. The ideal patch reduces bleeding and prevents recurrent blockage.This is looking at long-term results toward improvement with the use Accuseal patch than Bovine Patch.


Condition Intervention
Coronary Stenosis
Procedure: Comparing Accuseal Vs. Bovine Pericardial in CEA

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Prospective Randomized Trial Comparison of Accuseal and Bovine Pericardial Patch During Endarterectomy

Further study details as provided by CAMC Health System:

Primary Outcome Measures:
  • The aim of this study is to evaluate the perioperative and long-term complications (thrombosis of the carotid artery, and the degree of restenosis of the patched artery as determined by duplex ultrasound evaluation). [ Time Frame: within 30 days of operation,6 month, 1 year, 2 year, 3 year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • We hypothesize that the Accuseal patch will have a longer hemostasis time but a lower associated stroke rate and a longer time to restenosis than the Bovine Pericardial patch. [ Time Frame: within 30 days of operation,6 month, 1 year, 2 year, 3 year ] [ Designated as safety issue: No ]

Estimated Enrollment: 400
Study Start Date: September 2009
Estimated Study Completion Date: July 2013
Estimated Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)

Accuseal patch Procedure: Comparing Accuseal Vs. Bovine Pericardial in CEA

Accuseal patch - The Goretex Company has since designed a new patch, "the Accuseal," which is marketed as decreasing the intra-operative time (i.e, having a short hemostasis time) without affecting the perioperative stroke rate.

Bovine Pericardial patch - The Bovine Pericardial patch has been used for nearly two decades, since the late 1990s. However, studies based on retrospective review of data in which patients received the Bovine Pericardial patch, reported the clinical outcomes post-operative stroke, death, time to hemostasis and recurrent restenosis.

Detailed Description:

This study will be a prospective, randomized, evaluation comparing the outcomes resulting from the use of two different patches (Accuseal vs Bovine Pericardial) used for CEA.Our proposed study will evaluate the perioperative (within 30 days of operation) and long-term (6 month, 1 year, 2 year, 3 year) complications associated with the Accuseal and Bovine Pericardial patches. This will include thrombosis of the carotid artery, and the degree of recurrent plaque formation of the patched artery as determined by duplex ultrasound evaluation in the perioperative and long-term periods.Patients will be blinded to the type of patch they received.Survival analysis (Kaplan-Meier) (used in this case for time to the event analysis) will be used for time to restenosis, time to stroke, and time to late death.

  Eligibility

Ages Eligible for Study:   18 Years to 90 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population

The population includes Carotid Endarterectomy (CEA), surgical removal of the blockage in the neck artery patients.

Criteria

Inclusion Criteria:

  • Symptomatic patients with >50% stenosis or Asymptomatic patients >60% stenosis: i.e.: patients experiencing a neurological event(s) such as a trans-ischemic attack, cerebrovascular accident, amaurosis fugax, and/or a preoperative duplex ultrasound, magnetic resonance angiogram, or Angiogram indicative of severe > 60% carotid artery stenosis.

Exclusion Criteria:

  • will be enforced for those less than 18 years of age, patients who for religious reasons can not accept a Bovine Pericardial patch and those with a combined procedure ie: coronary artery bypass graft (CABG) and CEA.
