Description détaillée
We intend to examinate 100 consecutive persons that have calcifications in the area of the carotid arteries with carotid duplex-ultrasound. The prevalence of carotid stenoses > 50% (According to the NASCET criteria) in this group is the primary result of interest, answering the most fundamental question - should persons with calcifications in the area of the carotid arteries seen on panorama be screened with ultrasound in order to find asymptomatic carotid stenoses? Since the publication of the ACST and the ACAS studies it is clear that some of these patients might have indications for surgery.
A second part of the study aims to more fully understand what it is that the panorama examination reveals. In this part will 100 patients that are going to undergo surgery to remove their carotid stenoses will be examined with panorama. The carotid plaque that is removed during the surgery will be examined radiologically.
Primary endpoint:
- Subpopulation prevalence of carotid stenoses > 50% in persons with calcifications in the area of the carotid arteries seen in a panoramic examination.
Secondary endpoints:
- Statistical data (sensitivity, specificity, accuracy, likelihood ratio and predictive values) for panorama to find carotid stenoses with ultrasound as gold standard.
- Qualitative description of the relationship between panoramic calcification images and the removed carotid plaques.
AMENDMENT JUNE 2011: The different arms of the study will be published seperately.

Intervention / Traitement |
---|---|
Expérimental: Panorama to Ultrasound
100 asymptotic patients that have findings of calcifications in the area of the carotid arteries when examined with panorama.
These persons are examined with carotid ultrasound.
|
Ultrasonographic examination of the carotid arteries to determine the grade of carotid stenosis.
|
Expérimental: Ultrasound to Panorama
100 patients with a known carotid stenosis seen on ultrasound will be examined with panorama before any intervention is made.
These patients must undergo surgery to be finally included.
|
Examination with the odontological radiological method "Panorama", including a frontal verification image
