Prevalence of Carotid Artery Stenosis and Abdominal Aortic Aneurysms in Brussels: a Population-based Screening Study.

2019-09-26 05:42:38 | BioPortfolio


Both abdominal aortic aneurysm (AAA) and carotid artery stenosis (CAS) are frequent clinical entities, with major morbidity and mortality.

This project obtains robust data on the prevalence of AAA and CAS in the Brussels Capital Region. Using duplex ultrasound, a low invasive examination, we want to obtain information on a vast sample of men and women of the Brussels capital region, starting at the age of 60. With these data we can have a far better view on the Belgian situation of these two main vascular clinical entities. The data can provide insights on if, and how, Belgian public health policy can be improved concerning AAA and CAS.


A population-based screening study to determine the prevalence of carotid artery stenosis (CAS) and abdominal aortic aneurysms (AAA) in the Brussels Capital Region.

The study population is the 60+ inhabitants of the Brussels capital region; recruitment of 4680 subjects. Using duplex ultrasound, a low invasive examination, information is obtained on the abdominal aortic diameter and the degree of stenosis of the carotid bifurcation.

The objective is to determine not only the prevalence of, but also the risk factors associated with CAS and AAA among 60+ Brussels inhabitants. To collect these data, a questionnaire is made including demographic features, associated risk factors, but also previous treatment for AAA or CAS and the current medication of the subject.

Examination is done by one-time duplex ultrasound to perform a diameter measurement of the abdominal aorta and determine the degree of stenosis of the carotid arteries.

Data collection will be done in an electronic case report form, and statistical analysis will be done by a multi-variable logistic regression model.

Medical and Biotech [MESH] Definitions

Blood clot formation in any part of the CAROTID ARTERIES. This may produce CAROTID STENOSIS or occlusion of the vessel, leading to TRANSIENT ISCHEMIC ATTACK; CEREBRAL INFARCTION; or AMAUROSIS FUGAX.

Transient complete or partial monocular blindness due to retinal ischemia. This may be caused by emboli from the CAROTID ARTERY (usually in association with CAROTID STENOSIS) and other locations that enter the central RETINAL ARTERY. (From Adams et al., Principles of Neurology, 6th ed, p245)

Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION. (From Am J Forensic Med Pathol 1997, 18:251; J Trauma 1994, 37:473)

Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.

The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.
