The altered balance between the proteinases and their tissue inhibitors (TIMPS) is one of the pathogenetical mechanism of the aneurysmatic connective tissue degeneration. The increasement of protease, collagenase and elastase activity results indeed in a dramatic drop of collagen and elastin tissue and serum levels.Matrix Metalloproteinases (MMPs) are a group of proteolytic enzymes that along with their specific and non-specific inhibitors modulate the extracellular matrix composition. Recent studies have suggested an interesting role of microRNAs (miRNAs) in the regulation mechanisms of inflammation. The aim of our study is to analyse the influence of statin treatment on aneurysmatic disease by monitoring MMPs and miRNAs in aneurysmatic wall tissue and MMps blood levels.
Use of endovascular techniques - implantation of a peripheral stent graft and a peripheral flexible stent to isolate the sac of the popliteal artery aneurysm from the circulation and subsequent topical application of a thrombolytic (rtPA) to restore patency of the lower leg blood stream - will lead to a comparable or better outcome in treatment of patients with the popliteal artery aneurysm and acute critical limb ischaemia, compared to currently prevailing use of surgical treatment.
To determine the safety and efficacy of the BMFM® kit in the use for the endovascular treatment of aortic aneurysms involving iliac arteries. The BMFM® kit is an adaptation of the aortic MFM® to the aortoiliac bifurcation morphology. It should be noted that the aortic MFM® has CE mark approval for the aortic aneurysm treatment.
This is a national registry study to determine genetic risk factor and serial biomarkers of thoracic aortic aneurysm/dissection
The pupilometer determines the alteration of the pupil diameter after a defined light stimulus. In this study data is collected from pupilometer measurements of patients with an acute cerebral disease. The measurements take place during daily neurological routine examinations. The values are compared to outcomes resulting from pupilometer measurements done on patients having not an acute cerebral disease (e.g. cerebral aneurysm without symptoms). The study aims to establish the not invasive method of pupillometry for detecting neurological degradations early.
The purpose of this study is to assess the safety and effectiveness of the Artisse™ Intrasaccular Device in the treatment of unruptured and ruptured wide-neck bifurcating intracranial aneurysms.
Rupture of abdominal aortic aneurysms(AAA) causes 12,000 deaths/year in the UK.1 Elective repair to prevent this carries a perioperative mortality of 4.5% for open surgery and 1% for endovascular repair. This risk is associated with poor cardiorespiratory fitness which can be measured using Cardiopulmonary Exercise Testing(CPET) with the CPET variables, peak oxygen uptake(peakVO2)<15ml/kg/min and anaerobic threshold(AT)<10.2ml/kg/min identifying patients at increased risk of early death after AAA repair.3 These variables can therefore be used as surrogate markers for cardiovascular fitness and risk of mortality and morbidity in AAA surgery; optimising these markers should improve fitness and decrease this risk. The optimal duration and type of exercise training for improving peak VO2 and AT in AAA patients is not known. AAA patients are unique as they are motivated to reduce the risk of impending surgery but are afforded the time to improve their fitness as repair may not be needed for months or even years. The investigators propose a pilot randomised controlled trial to explore the effectiveness of a 20-week community (either home or gym-based) exercise programme to achieve sustained improvements in peak VO2 and AT, as measured by CPET, in AAA patients. Changes in QoL, habitual activity levels and cardiovascular risk will also be assessed. The results will inform a definitive multicentre clinical trial on exercise to improve outcomes in elderly patients with cardiovascular disease and AAA.
Multicenter, single arm, open label, registry study with consecutive, eligible patient enrollment at each site. All subjects undergoing the Endovascular Aneurysm Sealing System (EVAS) with the Nellix®-System. Subjects will be followed procedurally to discharge, and as per institutional standard of care thereafter through to 5 years (total follow-up commitment)
Stroke and abdominal aortic aneurysms (AAAs) are common and highly lethal vascular diseases. Angiogenesis and infiltration of inflammatory cells such as macrophages may cause stroke and AAAs. The purpose of this study is to test PET/CT and PET/MRI imaging to specifically detect those diseases using a new developed agent (18F-FPPRGD2) that can target angiogenesis and macrophages.
