The aorta is the main blood vessel that comes out of the heart and distributes blood to the whole body. In some people, the aorta becomes swollen (aneurysm) and bursts, especially as it passes through the abdomen. These 'abdominal aortic aneurysms' often occur without symptoms and can burst or rupture without warning. This usually leads to death and represents the thirteenth commonest cause of death in the United Kingdom. In this study, we are looking at a new technique that can look at the aortic aneurysm using magnetic resonance imaging; a technique that does not require x-rays or radiation. We have recently shown that, using magnetic resonance combined with a new imaging agent USPIO, we can detect 'hotspots' of activity in these aneurysms that seem to predict which aneurysms grow rapidly, and are therefore potentially at risk of rupture. We here propose to conduct a study in Edinburgh that will invite all patients who are under surveillance because of an aneurysm. We will image these patients using this novel technique and see if we can identify which patients burst their aneurysm, have an aneurysm that grows so large it needs to have surgery, or die. This will be important to establish as it will potentially lead to a new way of managing people that could ultimately save lives. This is particularly timely as national screening and surveillance programmes are currently being launched.
The purpose of this observational Post-Market Surveillance Registry is to gather post-market data on the performance of the CE marked Vascutek Anaconda™ Stent Graft System for the repair of Abdominal Aortic Aneurysms (AAA). The Study population consists of patients suitable for endovascular repair of AAA. Patients will be followed at 1, 3, 6, 12, 18, 24, 36, 48 and 60 months post-implantation.
The association between obesity and cardiovascular disease (CVD) has mostly been studied using broad endpoints or have focused on cause-specific mortality. The investigators aim to compare the effect of body mass index (BMI) on different types of initial presentation of CVD.
Major vascular surgery involves operations to repair swollen blood vessels, clear debris from blocked arteries or bypass blocked blood vessels. Patients with these problems are a high-risk surgical group as they have generalized blood vessel disease. These puts them at risk of major complications around the time of surgery such as heart attacks , strokes and death. The mortality following repair of a swollen main artery in the abdomen is about 1 in 20. This contrasts poorly with the 1 per 100 risk of death following a heart bypass. Simple and cost-effective methods are needed to reduce the risks of major vascular surgery. Remote ischaemic preconditioning (RIPC) may be such a technique. To induce RIPC, the blood supply to muscle in the patient's arm is interrupted for about 5 minutes. It is then restored for a further five minutes. This cycle is repeated three more times. The blood supply is interrupted simply by inflating a blood pressure cuff to maximum pressure. This repeated brief interruption of the muscular blood supply sends signals to critical organs such as the brain and heart, which are rendered temporarily resistant to damage from reduced blood supply. Several small randomized clinical trials in patients undergoing different types of major vascular surgery have demonstrated a potential benefit. This large, multi-centre trial aims to determine whether RIPC can reduce complications in routine practice.
The purpose of this study is to determine if telmisartan is effective in slowing the progression of abdominal aortic aneurysms and reducing circulating concentrations of Abdominal Aortic Aneurysms (AAA) biomarkers.
The management and delivery of intravenous fluids during surgical operations is one of the important duties for anesthesiologists. The goal of this study was to determine if goal directed fluid therapy, titrated using the FloTrac monitor's measurement of stroke volume variation results in a decrease in the length of stay of patients undergoing open abdominal aneurysm repair.
The purpose of this study is to determine the prevalence of abdominal aortic aneurysm (AAA) and abdominal aortic atheromatosis (AA-At) using a hand-held ultrasound by a general practitioner in Primary Health Care.
The purpose of this study is to evaluate the safety and effectiveness of InCraft® in subjects with abdominal aortic aneurysms requiring endovascular repair.
The Zenith® p-Branch™: Single-Center Study is a clinical trial approved by Swedish Regulatory Authority to study the safety and effectiveness of the Zenith® p-Branch™ in the treatment of abdominal aortic aneurysms.
