Weakening and expansion of the main abdominal artery (abdominal aortic aneurysm, AAA) is a common problem in older Australians. The majority of AAAs are small (<55 mm) and affect 90,000 individuals in Australia and 4.5 million world-wide. Currently, the only treatment available for AAA is surgery. However, surgical therapies are not effective for small AAAs, and these patients undergo a program of repeat imaging and consultation to monitor the size of the aneurysm and symptoms. This proposal is aimed at addressing the urgent need to identify a medical treatment able to limit progression of AAAs. The study design and rationale are based on strong preclinical evidence supporting the value of eplerenone (an agent indicated for treatment of heart failure) in limiting AAA progression. If proved effective, this medication would: 1. Reduce the number of patients requiring costly surgery 2. Reduce the number of surgery related deaths and complications 3. Provide a therapy suitable for the rapidly expanding elderly age group who have AAAs.
This post market registry consists of a retrospective and a prospective part. The first part is a retrospective registry of all implanted IBE devices of Gore in the Netherlands after CE mark was obtained, to get an initial insight on the feasibility and safety of this procedure. The second part is to prospectively register all data on implanted IBE Gore devices, in order to gain more robust data on the efficacy of the device in maintaining hypogastric artery patency.
Postoperative renal failure is the most significant risk factor for early mortality after elective surgical repair of thoracoabdominal aortic aneurysms (TAAAs). To prevent damages related to kidney ischemia during aortic crossclamping and TAAA repair, the most recent guidelines recommend the use of cold crystalloid or blood perfusion. Since the most studied crystalloid solution is the Ringer's lactate solution, this can be considered the standard of care for evaluating the effectiveness of other substrates. An histidine-tryptophan-ketoglutarate enriched crystalloid solution named Custodiol (Dr. Franz Kohler Chemie GmbH, Bensheim, Germany) is currently used for organ preservation during transplantation and for cardioplegia during open-heart surgery in most EU countries. This solution may provide a better grade of renal protection to ischemic damage than the standard crystalloid solutions. A recent observational study published by our group suggested a lower incidence of postoperative renal kidney injury in patients undergoing open TAAA surgical repair using renal perfusion with Custodiol, as compared to those perfused with an enriched Ringer's lactate solution. Objective of this study is the confirmation of the promising findings about the effectiveness of renal perfusion with Custodiol during repair of TAAA compared with other crystalloid. The study will be a prospective, single-center, randomized, double-blind, controlled trial, investigating Acute Kidney Injury in patients undergoing TAAA open repair using Custodiol renal perfusion versus an enriched Ringer's lactate solution. It is expected to enroll adult patients undergoing elective TAAA open repair. Participants will be followed for the duration of hospital stay, an expected average of 2 weeks.
Prospective, nonrandomized, single-center, two-arm study to assess the feasibility and safety and to evaluate clinical outcomes of endovascular repair of complex aortic aneurysms (thoracoabdominal aortic aneurysms and aortic arch aneurysms) in patients at high risk for open surgery.
This is a French Registry mandated by the French National Health Authority assessing long-term (5-years) safety of the GORE® Excluder® Endoprosthesis in the treatment of infra-renal Abdominal Aortic Aneurysms (AAA).
The study aims at screening Israeli Arab men, smokers or past smokers, for abdominal aortic aneurysms (AAA). The screening is to be performed at the family doctors clinics in the rural arab erea of the north of Israel. Goals: The investigators aim at revealing the actual prevalence of AAA in the Israeli Arab smoking men population. By revealing this prevalence we believe the need for a nation-wide screening program for AAA will turn available for assessment. In addition, the goal of improving the accessibility of health services for the Israeli Arab population is a key issue in the design of the research. 2000 patients are to be enrolled in the study over a period of 2 years. Each of the patients will be examined once for a duplex ultra-sound and will be classified into one of 4 sub-groups according to the maximal aortic diameter found.
The goal of this project is to establish a biobank of clinical information, DNA, plasma, and aortic tissue samples from patients with cardiovascular disease as well as healthy controls.
Abdominal Aortic Aneurysm (AAA) is a potentially life threatening condition. If the aneurysm ruptures, the mortality can be as high as 80%. Endovascular aneurysms repair (EVAR) is a minimal invasive procedure and has been widely used on treating AAA. Advanced endovascular techniques are used to treat patients with more complex pathology by using custom-made devices and additional stents. In order to accomplish the technical success on advanced EVAR, with the current imaging equipment and technique for EVAR procedures (i.e. live x-ray fluoroscopy and 2-D digital subtraction angiography (DSA)), multiple angiograms on the target arteries (arteriograms) are required. Subsequently patients are exposed to higher dose of contrast and radiation, compared to conventional EVAR. This study is to assess the feasibility of proper visceral and renal arteries catheterization using a 3D model obtained from pre-procedural computed tomographic angiography (CTA), fused with real-time fluoroscopy, without contrast injection or angiographic run-offs thus minimizing the contrast use and patient radiation exposure while achieving procedure success during Advanced EVAR.
The primary objective of the Visceral Manifold and Unitary Device Study is to assess the use of the thoracic bifurcation and the visceral manifold or the unitary device to repair thoracoabdominal aortic aneurysms in patients having appropriate anatomy. The primary intent of the study is to assess safety and preliminary effectiveness of the device. Additionally, the study will assess technical success and treatment success at each follow-up interval.
