Официальное название
Screening for Intracranial Unruptured Aneurysms in First-Degree Relatives of Patients With Aneurysmal Subarachnoid Hemorrhage
Обзор
The purpose of this study is to screen first-degree relatives of patients with aneurysmal subarachnoid hemorrhage using magnetic resonance angiography to detect unruptured intracranial aneurysms. This study aims to identify individuals who are at increased risk and determine the effect of environmental factors for development of unruptured intracranial aneurysms.
Подробное описание
The prevalence of intracranial aneurysms is 3-5% according to studies, while the annual incidence of complications in the form of bleeding from an intracranial aneurysm is 8-10 per 100 000 people. Subarachnoid hemorrhage is an urgent condition characterized by the extravasation of blood into the space surrounding the central nervous system, which is filled with cerebrospinal fluid. The leading cause of non-traumatic subarachnoid hemorrhage is the rupture of an intracranial aneurysm, accounting for approximately 80-85% of cases, and it is associated with a high rate of complications and mortality. Therefore, early detection of patients at elevated risk, monitoring, and management of unruptured intracranial aneurysms is of paramount importance.
Data suggest that first-degree relatives of a family member affected have higher risk for developing intracranial aneurysm. Screening in Relatives with Elevated Risk for Unruptured Intracranial Aneurysms is research effort of neurosurgeons and neuroradiologists to identify environmental factors in study population of Vojvodina (Serbia), that contribute to development of intracranial aneurysms. This study will involve at least 150 siblings (first-degree relatives) of patients who suffered aneurysmal stroke, and determine effect of demographics, environmental factors including, smoking, medical comorbidities and hypertension, caffeinated drink consumption, and hard physical work on the development of unruptured intracranial aneurysms (UIAs). This study of affected families and individuals, known as Screening in Relatives with Elevated Risk for Unruptured Intracranial Aneurysms (SIREN) study, is sponsored by Provincial Secretariat of Health of the Autonomous Province of Vojvodina (Special Screening Program).
This study will also involve at least 150 individuals with no past family history of aneurysmal stroke or UIAs. SIREN study will take part in Autonomous Province in Vojvodina only.
In order to be eligible for the study, individuals with affected family member that was admitted to study center for aneurysmal stroke, had to be older than 30 years of age, and first-degree relatives (father, mother, sister, brother, daughter, or son).
Participants will be asked to complete informed consent and questionnaire with past medical and family history. After completing questionnaires, their arterial blood pressure will be measured. Participants will receive no monetary compensation for participation.
Identification of demographic and environmental risk factors contributing to development of UIAs in families of affected individuals may result in early detection of ones at risk and potentially prevent formation of UIAs or complications including aneurysmal stroke.
