Filter by: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 prospective study is to compare point-of-care focused cardiac ultrasound (FOCUS) to thoracic computed tomographic angiography (CTA) in the measurement of ascending aortic dimensions. We hypothesize that FOCUS will demonstrate good agreement with CTA in the measurement of ascending aortic dimensions and accurately detect dilation and aneurysmal disease.
The purpose of this study is to investigate how dexmedetomidine affects static and dynamic autoregulation, intracranial pressure (ICP) and cerebral oxygenation in aneurysmal subarachnoid haemorrhage (SAH) patients.
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.
Surgery on the aorta can be associated with significant blood loss. Most commonly this is due to bleeding at the site of aortic anastomosis. Surgical bleeding is associated with significant morbidity. One way to prevent bleeding is to use a special glue (sealant) after performing large connections on the aorta. The goal of this study is to compare the different methods surgeons use to stop/prevent bleeding. The study team will collect medical information about patients before, during, and after surgery on their aortas, including the methods used to prevent bleeding. This information may help doctors improve the way that they care for these patients.
The Zenith® p-Branch® and Zenith® Fenestrated AAA Endovascular Graft Single-Center Study is a clinical trial approved by US FDA to study the safety and effectiveness of the Zenith® p-Branch® and Zenith® Fenestrated AAA Endovascular Graft in the treatment of abdominal aortic aneurysms.
Screening studies for Abdominal Aortic Aneurysms (AAA) in 65 to 79 years aged men, have shown a significant reduction in AAA related mortality. In addition, the cost-effectiveness of screening for AAA in men in the Netherlands has been demonstrated by using a Markov model. Screening might be even more (cost-) effective if targeted on high risk groups, such as patients with a particular cardiovascular disease with a known increased risk of having an AAA. Project SCAN (Screening CardioVascular patients for Aortic aNeurysms) is a project focused on targeted AAA screening to proactively diagnose patients at high risk of having an aneurysm that eventually may rupture. This pilot project aims to study the value of a screening protocol in daily practice to detect AAA's in high risk patients.
To assess the safety and effectiveness of the Penumbra Liberty Stent System as adjunctive treatment to embolic coils for wide-neck, saccular, intracranial aneurysms in the internal carotid artery (ICA). The Liberty Stent System is an implantable device comprised of a stent and delivery system designed as an adjunct to embolic coils in the treatment of wide-neck, saccular, intracranial aneurysms. It has three components: an implant, an introducer sheath and a delivery wire assembly. The implant component is made of superelastic and biocompatible nitinol tubular material. Patients presenting with wide-neck, saccular, intracranial aneurysms in the internal carotid artery (ICA) from the cavernous segment to the carotid terminus (including the paraclinoid, ophthalmic, hypophyseal and posterior communicating segments) will receive stent assisted coiling by the Penumbra Liberty Stent with any approved embolic coils currently on the market. Wide-neck aneurysms are defined by a neck ≥4mm or a dome-to-neck ratio <2. Each patient will be followed and assessed for 2, 6 and 12 months after enrollment.
Ongoing technological advances, especially in the field of image processing, have refined medical simulations to offer life-like replications of medical and surgical procedures in a variety of specialties. Patient-specific image data are incorporated into these simulations, and transformed into a 3D model. This enables the practitioner and his/her team to perform and practice 'real' cases on a virtual patient prior to performing the real procedure on the actual patient. This new technology has been referred to as 'patient-specific' rehearsal, also 'mission' or 'procedure' rehearsal. Research has already proven that simulated patient-specific rehearsal of a carotid artery stenting procedure may enhance surgical and team performance. The PROcedure rehearsal software can now also be used to practice patient-specific endovascular repair of infrarenal aortic aneurysms (EVAR). The ability to rehearse a challenging and complex procedure like EVAR may not only influence device selection based on preoperative planning, but also improve the technical performance of the surgeon/radiologist and the awareness and communication within the entire endovascular team. However, further research is needed to evaluate if this new technology may enhance clinical safety and efficiency, i.e. if patients actually benefit from physicians and team members conducting patient-specific rehearsals of EVAR interventions.
