Eligible patients will be included as subjects in this study. Study subjects will receive an abdominal ultrasound (US) focused on the aorta. Detecting an AAA on abdominal US will result in the daily standard of care for AAA, including surveillance and possible treatment by medication, intervention or surgery.\n\nStudy sites This study will be conducted by the Department of Surgery in the main study location University Medical Center Leiden (LUMC) in collaboration with University Neurosurgical Center Holland (UNCH).

Inclusion stops when the targeted number of study subjects (N=233) is reached. The study duration is expected to be around 1.5 years and the study period will end when all 233 study subjects had an abdominal US, or were excluded from the study during the study period for particular reasons.","All aSAH patients from a large prospective cohort trial in the Netherlands will be screened for eligibility(12). The Study on Prognosis of Acutely RupTured Aneurysms (SPARTA) is an observational prospective cohort trial conducted in the Netherlands in several clinical centres. The aim of this study is to evaluate the long-term clinical outcome of aSAH patients who underwent neurosurgical- or endovascular treatment for their ruptured IA. The study has a population of around 900 patients. Because of the lethality of aSAH, a large proportion of this study population will be diseased or heavily incapacitated.",[24],{"label":25,"type":17,"description":22,"interventionNames":17},"Patients with aSAH from the SPARTA trial",[27],{"name":28,"affiliation":29,"role":30},"Jeroen Brouwers, MD, PhD","Leiden University Medical Centre","PRINCIPAL_INVESTIGATOR",[32],{"name":33,"role":34,"phone":35,"phoneExt":17,"email":36},"Alexander Hamming, MD","CONTACT","+31655322609","a.hamming@haaglandenmc.nl",[38],{"facility":39,"status":40,"city":41,"state":17,"zip":17,"country":42,"countryCode":43,"cosmosGeoPoint":44,"geoPoint":49,"contacts":17},"LUMC","RECRUITING","Leiden","Netherlands","NL",{"type":45,"coordinates":46},"Point",[47,48],4.49306,52.15833,{"lat":48,"lon":47},{"type":30,"investigatorFullName":51,"investigatorTitle":52,"investigatorAffiliation":5,"oldNameTitle":17,"oldOrganization":17},"Jeroen J.W.M.

In literature, concurrence of intracranial- and aortic aneurysms is described. Screening for aortic aneurysms (AA) in patients with intracranial aneurysms (IA) or aneurysmal subarachnoid haemorrhage (aSAH) could be cost-effective and of significant importance to decrease morbidity and mortality. The available literature on the association between the two types of aneurysms is sparse and in general of poor methodological quality. This protocol presents a study to more adequately evaluate the association between IA and AA.\n\nObjective: To investigate the occurrence of abdominal aortic aneurysms (AAA) in patients who experienced aSAH.\n\nStudy design: This single cohort prospective study will include patients who experienced aSAH. The study participants will receive an abdominal ultrasound of the aorta to detect an AAA.\n\nStudy population: aSAH patients from a prospective cohort trial in the Netherlands.\n\nMain study parameters\u002Fendpoints: The primary outcome, which will be investigated in the here above described study population, is the number of AAA detected on abdominal ultrasound.\n\nNature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients will not receive an intervention, but only a diagnostic imaging without radiation. The burden associated with this study are considered minimal and the risks negligible. An abdominal ultrasound is a non-invasive diagnostic method with no risks for the participant. The only possible existing burden to the participant is travel and appointment time with a risk of detecting an abdominal aortic aneurysm or other (occult) intra-abdominal pathologies. When an aneurysm, sub-aneurysm or other intra-abdominal pathology is detected, surveillance or treatment according to standard of care and guidelines will follow.",[69,70],"Aneurysm Abdominal","Cerebral Aneurysm Ruptured",[72,73,74,75,76],"abdominal aortic aneurysm","aneurysmal subarachnoid hemorrhage","ruptured intracranial aneurysm","prospective single cohort study","ultrasound","2026-08-24",{"date":79,"type":80},"2026-08-25","ACTUAL",{"date":82,"type":80},"2026-06-01",{"date":84,"type":65},"2026-12-01",{"name":5,"class":6},1]
