Filter by:Prospective, randomized, multi-center study designed to evaluate the outcomes of commercially available contemporary EVAR in a real-world population. Patients will be randomized into two device cohorts and compared across the primary endpoints. Patients will be followed procedurally to discharge, at 1, 6, 12 months and annually through to 5 years (total follow-up commitment).
A retrospective cohort study of computed tomography scans of AAA patients considered for repair, in order to identify sex specific differences in abdominal aortic aneurysm (AAA) metrics and the association between anatomical differences/features of complexity and adverse patient outcome.
Thoracic aneurysm is a silent disease with a potential mid-term high risk of death or major complications. Few data are available on the real incidence of major complications in case of small and moderate thoracic aneurysm. Different factors are supposed to increase the risk of aortic enlargement as high blood pressure and sleep disorder breathing. The modality of imaging and clinical follow-up are well defined. In this prospective observational study, the aim to assess the incidence of of major complications during follow-up in a population of patients with a small or moderate thoracic aneurysm. The study will also try to identify systemic factors influencing aneurysm evolution.
The aorta is the principal arterial vessel arising from the left heart that transfers blood to the body. Certain genetic and familial disease processes are known to weaken the aortic wall resulting in dilation and potential rupture. These aortic complications carry high mortality (>25%) and current management is orientated towards early detection and preventive treatment. Aortic dilation can also result in aortic valve dysfunction leading to heart failure. The estimated UK incidence of aortic disease per year is around 10 per 100,000 individuals, with 2000 people per year dying from aortic complications. The 2017-2020 National Adult Cardiac Surgery Audit report identified the number of people receiving surgery for aortic dissection in Scotland is per population proportionately lower compared to England (4.6 per million per year in Scotland vs. 6.6 per million per year in England). The reasons for this are unclear but may relate to the prevalence of aortic disease or a large geographic distribution with compromised access to specialized centres. Currently surgery is recommended when the aortic diameter exceeds a certain threshold. There are several types of effective surgical procedures, but there is still limited information on their long-term outcomes and the advantage of one procedure over another. The aims of the project are firstly to determine the clinical outcomes of the surgical procedures that are currently employed in Scotland to treat proximal aortic disease and secondly to describe the prevalence and distribution of proximal aortic disease within the Scottish population. The project will be hosted by the Golden Jubilee Research Institute. Contemporary and retrospective data will be collected from all the Scottish Cardiothoracic Surgery units which are based in Glasgow, Edinburgh and Aberdeen. This will be the first study to analyse surgical outcomes for ascending aortic disease in Scotland, and the first to describe the epidemiology of aortic disease within the population. It is anticipated that the results will guide current surgical practise, and provide data to inform national service provision for the management of proximal aortic disease.
COIN trial is a a prospective, randomized, placebo-controlled, double-blind, multicenter clinical study. Approximately 230 patients with small abdominal aortic aneurysms (AAA) will be randomly allocated to low-dose colchicine group or placebo group. All study patients will be followed up in the outpatient clinic every 3 months and undergo CTA scans after 24 months from randomization. The primary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA diameter. The secondary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA volume, reduce the incidence of clinical outcomes associated with AAA, reduce the incidence of major adverse cardiovascular events and all-cause mortality.
A prospective observational cohort study to assess the eligibility, uptake, viability, acceptability, safety, and cost of a ShorT stay (23-hour) Aneurysm Repair (STAR) pathway. Outcomes will be collected for up to 1 year.
It is recognised that women are at greater risk of death, complications and longer hospital stay following intact abdominal aortic aneurysm (AAA) repair, and the reason for this is not yet established. This disparity in outcomes for women compared to men is also recognised in other forms of cardiovascular surgery, which raises the question of whether women and men are reacting differently to the stress of operative repair. This study aims to examine whether there are differences baseline stress markers and in the stress response to AAA repair between men and women. It will also examine whether markers of stress are associated with poor clinical outcomes and slower recovery (indicated by longer hospital stay). The study will take the form of an observational cohort study. It will not alter any of the treatment that men and women receive, but will monitor their stress levels using physiological markers (through ECG (electrocardiogram) monitoring using a non-invasive holter, biochemical markers using blood samples (which will be taken at the same time as routine testing, so as not to require further invasive procedures), and psychological testing, using short forms that the patient will be able to fill out independently at different stages of their recovery. Clinical data will be used to look for relevant factors (clinical history or medications) which may alter the stress markers we are observing, and to compare outcomes with markers of stress. Patients will be asked for their consent to share their data with the research team in order to participate in the study. It will be made clear that there will be no change in their clinical or operative management if they participate in the study and they will be able to withdraw consent for further participation at any time.
The strength of movement which are applied on the EVAR are not only cranio-caudal but also lateral. The movement of the EVAR's body within the aneurysm could be an instability's criteria of the EVAR. The investigators would like to show that this lateral movement is a risk factor of reintervention they should follow and suggest a reinforced medical follow-up to avoid complications.
Post-stent rupture of the abdominal aorta is a rare occurrence and with few publications: only 2 multicenter studies and one meta-analysis in 2017 listed this complication As well as a few cases reports This study, the first carried out in France, aims to describe the survival in patients with secondary rupture of the aneurysm despite initial treatment with EVAR.
Aortic dissection or aneurysm is unusual in young patients, and frequently associated with unusual presentations. However studies about this area is scarce. Besides, the treatment option is not clare. The prognosis of this cohort is also unclear. The goal of this study was to better understand the characters, treatment option and prognosis of young patient with aortic dissection or aneurysm.
