Filter by:The purpose of this study is to compare the contrast agents and imaging techniques used for thoracoabdominal aortic imaging in CT. Imaging parameters and contrast volume are changed and adjusted based on the contrast agent, since contrast agents have varying iodine concentrations. If the contrast iodine concentration is higher, it may be possible to adjust the imaging parameters and lower the overall radiation dose to the patient.
The purpose of this study is to assess the clinical outcomes and radiation of the use of off-the-shelf and custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal, thoracoabdominal and arch aortic aneurysms in patients having appropriate anatomy. The study consists of three cohorts. The first 2 cohorts are the continuation of the current IDE study. The first cohort is aimed to assess the use of custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal and type IV thoracoabdominal aortic aneurysms in standard and high-risk patients having appropriate anatomy (Fenestrated-CMD cohort). The second cohort (Type I-III thoracoabdominal cohort) includes standard and high-risk patients with type I- III thoracoabdominal aneurysms that require the use of branched/fenestrated CMDs, or, in selected cases, the Zenith Thoracoabdominal Branch (Zenith® t-Branch™) device. Finally, the third cohort (the Arch cohort) will include 25 high-risk patients with aortic arch aneurysms treated by patient-specific stent-grafts with one to three inner branches or a scallop
This is a French Registry mandated by the French National Health Authority assessing long-term (5-years) safety of the GORE® TAG® Thoracic Endoprosthesis treating diseases of the thoracic aorta.
The primary objectives of the study are - to assess the contribution of alteration of each known gene on non-syndromic TAA. - to map and identify unknown gene involved in the non-syndromic TAA.
Effects of OctaplasLG® on endothelial integrity in patients undergoing emergency surgery for thoracic aortic dissections - a randomized, controlled, single-blinded investigator-initiated pilot trial
The primary objective of this study is to determine whether specific patterns of circulating micro-ribonucleic acids (miRNAs) are associated with aortic aneurysm and dissection in patients with hereditary aortopathy syndromes. The most common of these syndromes is Marfan Syndrome (MFS), but several other recognized aortopathy syndromes are well characterized. The investigators propose the use of a simple blood test, from which miRNA profiles can be measured in individuals with aortopathy syndromes to be compared with miRNAs observed in a control population that has no known predisposition for aortic disease. The investigators hypothesize that microRNA profiles in individuals with Marfan syndrome, and related disorders, will be distinct from those seen in a control group. The investigators predict that up- or down-regulation of certain miRNAs will correlate with the presence and severity of aortic aneurysm, responses to medical therapy, and ultimately could be used to determine when an individual may be at risk of dissection.
The objective of this prospective cohort study in patients with a known thoracic aortic aneurysm is to test the hypothesis that yearly aneurysm progression rate is higher in patients with obstructive sleep apnoea (OSA) compared to patients without OSA, and that the need for aortic operation or proven or presumed death from aortic rupture or dissection happens more often in patients with thoracic aortic aneurysm and OSA compared to patients without OSA.
This is a prospective, multicenter, single-arm study designed to collect clinical data to support the safety and effectiveness of BioFoam used as a surgical adjunct to anastomotic hemostasis following cardiovascular surgery. The overall objective of this clinical study is to collect clinical data supporting the safety and effectiveness of BioFoam used as a surgical adjunct to anastomotic hemostasis following cardiovascular surgery. This study is intended as a post-market surveillance (follow-up) study.
The purpose of this study is to assess the feasibility of the use of the GORE® TAG® Thoracic Branch Endoprosthesis to treat aneurysms involving the proximal Descending Thoracic Aorta (DTA)
This is a prospective observational cohort study that will collect data from the point of referral through to secondary care, aiming for 3 years median follow-up (range 1-5 years). The data collected will allow estimation of the success of any intervention (in terms of reducing rate of aneurysm growth, rupture or dissection) as well as estimation of the risks associated with the three procedures. Clinical outcomes in the three treatment groups will be described. Aims We aim to answer the following questions: 1. Without procedural intervention for chronic thoracic aortic aneurysm (CTAA), what is the risk of aneurysm growth, dissection, rupture, permanent neurological injury or death? What is the effect on quality of life (QoL)? 2. If a patient has endovascular stent grafting (ESG) or open surgical repair (OSR), what is the risk of growth, dissection, rupture, permanent neurological injury or death? 3. How does QoL change from pre- to post intervention? 4. Can aneurysm or patient related predictors of good/poor treatment outcomes be determined? 5. What is the most cost-effective strategy in: 1. Patients eligible for either ESG or OSR? 2. Patients eligible for either ESG or best medical therapy (BMT)? 3. Patients eligible for either watchful waiting (WW) or intervention (ESG/ OSR)? 6. What further research is required? What would be the most important research to pursue?
