Filter by:Exercise testing is commonly being used in patients before surgery to test their overall fitness. One group it is being used in is patients who have an enlarged blood vessel in their stomach. This is known as an abdominal aortic aneurysm. The exercise test used is known as a cardiopulmonary exercise test as it looks at both heart and lung function at the same time. Whilst this test is commonly used there have been no studies (to date) which have looked at how reliable this test is; this means how well the investigators can obtain the same (or very similar) results after multiple tests. The investigators would like to test this reliability both between patients and the clinicians performing the testing.
A prospective clinical evaluation of the effectiveness of the Ovation Alto Abdominal Stent Graft System when used in the treatment of subjects with abdominal aortic aneurysm (AAA).
This study will evaluate a randomized comparison of direct versus snare techniques for cannulation of contralateral gate during an endovascular aneurysm repair (EVAR) procedure. This information will be used to determine if primary snaring is superior to retrograde cannulation in decreasing procedural time and radiation exposure.
The study aims to investigate the existence of a reliable correlation between the progression of aortic diameters and blood levels of circulant endothelial progenitor cells CD34+ in patients with not surgical aortic aneurysms.
The First In Human (FIH) study is a long-term, single center, non-randomized study established by Lombard Medical, Inc. to collect "on-label" data in the clinical setting on patients undergoing endovascular repair with IntelliFlex™, the latest generation of the Aorfix™ AAA Flexible Stent Graft Delivery System, for treatment of abdominal aortic and aorto-iliac aneurysms in anatomy where the aorta in the aneurysm neck is bent through an angle between 0° and 90°.
This is a randomized prospective monocentric study to evaluate the benefits of a 3D rotational acquisition (3DRA) to assess technical success after treatment of infra-renal aneurysm with bifurcated endograft. Patients will be randomized between the standard strategy (2D angiography at the end of the procedure and angioCT-scan before discharge) and the new strategy (3DRA at the end of the procedure). Expected findings are a reduction of radiation exposure and contrast medium used during the hospital stay, with a similar resolution between angioCT-scan and 3DRA to depict the main complications after EVAR (occlusion, kinking, endoleak). Furthermore, any complication depicted after 3DRA group could benefit from an additional procedure during the same operating time, and therefore avoid a second intervention for the patient.
This study aims to compare the results of two mini invasive surgical approaches in abdominal aortic surgery: mini lumbotomy with retroperitoneal approach versus mini laparotomy with transperitoneal approach. Respiratory and renal functions and recovery of intestinal transit will be assessed after 30 days. The secondary purpose of this study is to assess the life quality and morbi-mortality at 30 days, as well as at 6 and 12 months.
Screening for an abdominal aortic aneurysm, monitoring its growth and evaluation of its risk of rupture are based on the measure of its maximum diameter. The abdominal aortic aneurysm's treatment to prevent its rupture is recommended from a threshold of 50-55 mm in men and of 45-50 mm in women. The importance of this measure for patient management justify a specific and homogeneous protocol of measure. However, the diversity of methods of measuring the maximum diameter with scanner and ultrasound was shown. The impact of various angio-CT based measures of maximum AAA diameter, and the impact of reproducibility limits on the decision to operate have never been investigated.
The purpose of this study is to examine the percentage of patients who present with abdominal aortic aneurysms (AAA) will also have intracranial aneurysms (IA) and conversely; to examine the percentage of patients who present with intracranial aneurysms will also have abdominal aortic aneurysms.
The aim of the study is to assess if venous distension in patients with aneurysmatic arteriopathy is higher compared to patients with peripheral arterial occlusive disease (PAOD) and in controls.
