Comparison of Eversion and Conventional Techniques in Carotid Endarterectomy

January 1, 2026 updated by: İsmail DAL, Kastamonu University

Comparison of Operative and Early Postoperative Outcomes Between Eversion and Conventional Techniques in Carotid Endarterectomy

Atherosclerotic carotid artery disease is responsible for approximately 20% of strokes worldwide, and its treatment options include medical therapy, surgery, and stenting.Surgical management is prioritized over medical and stent based approaches and can be performed using either the conventional methed closed primarily or with a patch or the eversion technique.The aim of this study was to compare the intraoperative and early postoperative outcomes of the eversion technique and the conventional method with primary closure.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Carotid endarterectomy was performed in patients with 50-99% stenosis who had experienced stroke or transient ischemic attack (TIA) within the last six months, as well as in asymptomatic patients with 70-99% stenosis. These patients were divided into two groups according to the surgical technique applied conventional or eversion carotid endarterectomy and intraoperative and early postoperative outcomes were compared between the groups.

Description

Inclusion Criteria:

-Patients undergoing isolated carotid endarterectomy, either emergently or electively

Exclusion Criteria:

  • Patients younger than 18 years of age
  • Patients scheduled for concomitant cardiac surgery
  • Reoperations

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Conventional endarterectomy
Who were performed conventional,primarily endarterectomy patients are included this group
Procedure: Carotid endarterectomy, conventional
In this study, patients were divided into two groups according to whether they underwent conventional or eversion endarterectomy. Although the eversion technique is the oldest method, the conventional approach is still widely performed due to its ease of application, despite not being recommended in current guidelines. Therefore, our aim is to contribute to the literature by comparing these two methods. The conventional method is performed with a longitudinal incision extending from the common carotid artery (CCA) to the internal carotid artery (ICA) up to the end of the plaque. The arteriotomy is then closed either primarily or with the use of a patch. In our study, we performed only the primary closure method..
Eversion
Who were performed eversion endarterectomy patients are included this group
Procedure: Carotid endarterectomy, eversion
In this study, patients were divided into two groups according to whether they underwent conventional or eversion endarterectomy. Although the eversion technique is the oldest method, the conventional approach is still widely performed due to its ease of application, despite not being recommended in current guidelines. Therefore, our aim is to contribute to the literature by comparing these two methods.The eversion method is performed by transecting the internal carotid artery (ICA) from the common carotid artery (CCA). The arteriotomy is then closed in an end to side fashion.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of participants with stroke and death
Time Frame: 30 days
All strokes and/or deaths occurring within 30 days after surgery
30 days
Number of participants with symptoms of occlusion
Time Frame: Postoperative 30 days
Early carotid restenosis or occlusion within 30 days after surgery
Postoperative 30 days

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 15, 2025

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
