Filter by:The investigators want to test a navigation system for guidance during insertion of stent graft in abdominal aortic aneurysms. The navigation system consists of software developed by SINTEF Health, a custom made catheter with a micro position sensor in the tip and an emitter than induces an electromagnetic field around the patient. Preoperative CT- and intraoperative DynaCT- data are reconstructed into 3 dimensional images. The 3 dimensional images are loaded into the navigation system. Then the magnetic field, in which the patient finds himself, is calibrated with the 3 dimensional images. When the catheter is inserted into the iliac artery and aorta, the position sensor (in the tip of the catheter) is displayed in real time at the exact anatomic location in the 3 dimensional image. Null hypothesis (H0): - Insertion of stent graft is performed equally satisfactorily with fluoroscopy alone as with both fluoroscopy and new navigation technology Alternative hypothesis (H2): - Insertion of stent graft is NOT performed equally satisfactorily with fluoroscopy alone as with both fluoroscopy and new navigation technology
An abdominal aortic aneurysm (AAA) is a weakened and enlarged area in the abdominal aorta, which is a large blood vessel in the abdomen. If an AAA ruptures, it can be life-threatening. Research has shown that sedentary individuals are at increased risk of developing AAAs. This study will evaluate the effectiveness of an exercise program at limiting the growth of small AAAs in older individuals.
The purpose of this study is to assess whether treatment with melatonin can reduce cell damage and inflammatory stress response and thereby occurrence of myocardial injury after abdominal aortic surgery.
After endovascular abdominal aortic aneurysm repair, life-long follow-up is needed to monitor the effectiveness of exclusion of the aneurysm sac from blood flow. For this reason, aneurysm diameter and the presence of endoleaks is evaluated with CT angiography yearly after Endovascular Aneurysm Repair (EVAR). The aim of this study is to investigate the value of MRA examinations for the follow-up of these patients. The advantages of MRA with respect to CTA are no use of ionizing radiation, use of less nephrotoxic contrast agents.
The aim of this study is to evaluate a new way to create CT-like images during intra-operative procedures. We want to prove that the quality and information received from DynaCT is satisfactory in implementing stent-graft in abdominal aortic aneurysm.
The objective of this study is to assess the safety and effectiveness of the Cordis Bilateral AAA device and its Delivery System compared to open surgical repair for the treatment of Abdominal Aortic Aneurysm (AAA).
The objective of this clinical study is to assess the safety and effectiveness of the Cordis Endovascular Quantum LP™ Stent Graft System.
The purpose of this study is to compare the cost effectiveness, quality of life and outcomes of the endovascular stent graft repair with the open surgical repair of abdominal aortic aneurysms.
Abdominal aortic aneurysm (AAA) is a life threatening disease. There is a consensus to propose surgical repair in patients with a reasonable operative risk when the AAA exceeds 5 cm in diameter. The aim of the study is to compare the mortality and the occurrence of severe general, vascular and local complications in two groups of patients treated by either by open surgery or by EVAR (EndoVascular Aneurysm Repair). The main outcome criteria and the secondary endpoint are respectively the survival without severe complications and minor morbidity.
The purpose of this study is to evaluate the safety and effectiveness of the Cook Zenith Endovascular Graft for the treatment of abdominal aortic (AAA), aortoiliac, and iliac aneurysms.
