Filter by:This trial evaluates surgeon-modified fenestrated-branched stent-grafts (sm-FBSG) for Abdominal Aortic Aneurysms (AAA) that are custom-made intra-operatively with no waiting period by a qualified vascular surgeon. In addition, it aims to examine the alternative sm-FBSG for patients with restricted access to centers performing clinical trials with commercially available devices and those patients with aortic emergencies.
The purpose of this study is to determine whether intra- and postoperative use of the cardioPAT® cell saver decreases the need for allogenic red blood cell transfusion in patients, who undergo open heart surgery (with cardiopulmonary bypass) and preoperatively have an increased risk for bleeding.
This study was designed to assess the safety, tolerability and efficacy of ACZ885 on aneurysmal growth rate in subjects with abdominal aortic aneurysms (AAA). The purpose of the study was to provide data to enable decisions regarding the further development of ACZ885 for subjects with abdominal aortic aneurysms. The design of this study addressed the primary objective of evaluating the change in aneurysmal size in subjects with AAA as a result of treatment with ACZ885.
Seizures are a potential complication of surgical repair of intracranial aneurysms. In order to prevent seizures, many surgeons administer prophylactic anti-epileptic medication during the intra-operative and post-operative period, however, such practice is not supported by clinical data. Retrospective review found the incidence of postoperative seizures was higher in those who received anti-epileptics versus those who did not. The goal is to examine the utility of levetiracetam (Keppra) for seizure prophylaxis in patients undergoing surgical repair of unruptured intracranial aneurysms.
This is a multicenter, non-randomized, single arm, retrospective study of GORE® VIABAHN® Endoprosthesis for the treatment of a Popliteal Artery Aneurysm (PAA).
X-ray computed tomography imaging (CT) is routinely used in follow-up after endovascular aneurysm repair (EVAR). Contrast-enhanced ultrasound (CEUS) has been shown to give accurate information about endoleak after EVAR. Benefits of CEUS over CT include less radiation exposure, avoidance of renal function deterioration due to repeated X-ray contrast agent application and decrease in the cost of EVAR follow-up. This study is designed to investigate if results from literature are reproducible in St Olavs Hospital in Trondheim (Norway), to gain experience with the technique and to introduce CEUS as an alternative for detection of endoleak in this hospital.
Weakness in the wall of a blood vessel located behind the knee (popliteal artery) which leads to a swelling of this blood vessel (aneurysm) is one of the most common types of arterial aneurysms. It is associated with significant risk of blood clot formation, narrowing of blood vessel which can create a serious threat to individual's health. Currently, approved treatment options for this condition include both open surgical and endovascular stent-graft repairs. In the open repair procedure, the blood vessel behind the knee is tied up or removed and a small artery is created using a vein on the same leg. This is also called a bypass procedure. In the endovascular repair, using X-rays, doctors places a stent in the blood vessel. Stent is a small device similar to a thin tube. When it is placed in the right location, your doctor can open it. When stent is opened, it supports weakened blood vessel and blood goes through it. The weakened artery then shrinks around the stent. The OVER-PAR is a short name for this study. Many hospitals in the United States agreed to participate in this study. Patients are randomized to undergo either open or endovascular repair because they can be treated with either of the procedures. Investigators use the short names OPAR for open surgical repair and EPAR for endovascular repair. People who have an aneurysm that is larger than 2 cm (about an inch) can participate in this study. The purpose of this study is to compare outcomes after these two standard procedures.
An abdominal aortic aneurysm (AAA) is an enlargement or ballooning of the main artery supplying high pressure blood from the heart to the body. AAAs may continue to stretch until they burst (rupture) causing 7000 deaths per year in the United Kingdom (UK); 2.1% of all deaths in men over 65. Planned repair before rupture is critical and the National AAA Screening Programme (NAAASP) is being introduced to identify AAAs in men before rupture. Screening will identify over 9000 men per year with a previously undiagnosed AAA. More than 90% of screen detected AAAs are small, do no require repair, enter ultrasound follow-up (surveillance) and may benefit from exercise to improve fitness before repair. Over 4000 elective AAA repairs per year are performed in the UK and it has been suggested that exercise training and weight loss may reduce mortality and complications of AAA repair. This pilot study will examine the feasibility of supervised exercise training for patients with AAAs and determine the optimal duration of training to achieve worthwhile improvements in fitness.
Test single nucleotide polymorphisms (SNP's) in ruptured and unruptured aneurysm tissue to identify a genetic difference between the two types of aneurysms; and to test SNP's in arteriovenous malformation tissue to identify a genetic link.
Alzheimer's disease represents a growing public health problem in developed countries. Although the pathogenesis is not clearly defined, accumulation of extracellular amyloid, neurofibrillary tangles and neuronal loss are the hallmarks of Alzheimer's disease. The effect of anesthetic agents on changes in these proteins in humans is not well characterized, but in-vitro evidence suggests that anesthetic agents can accelerate potential pathogenic mechanisms, such as increasing amyloid formation or rates of apoptosis in cultured cells and increasing amyloid levels in mice. Human data on the effect of anesthetic agents on amyloid and tau proteins is limited to a small series of 11 patients and showed a significant increase in tau levels after exposure to anesthetics. In this study we propose to measure CSF and serum biomarkers in a population of patients with normal CSF dynamics, who are undergoing surgery for repair of a thoracoabdominal aneurysm. We will also obtain preliminary data on whether changes in CSF levels of these proteins are associated with postoperative delirium or cognitive change.
