Filter by:Elective minilaparatomy abdominal aortic aneurysm (AAA) repair is associated with a significant number of complications involving respiratory, cardiovascular, gastrointestinal and central nervous system, and mortality ranging up to 5%. In our study, we tested the hypothesis that intraoperative and postoperative intravenous restrictive fluid regime reduces postoperative morbidity and mortality and improves the outcome of the treatment of minilaparotomy AAA repair.
This study will test the hypothesis that GSK1278863 will reduce neurologic, renal, and/or cardiac ischemia in patients undergoing elective descending thoracic aorta/thoracoabdominal aortic aneurysm (DTA/TAAA) repair, a population known to be at high risk for ischemic events from their underlying pathology and the surgical complexity required to address their disease. Approximately 160 subjects will be stratified according to intervention type (surgical or endovascular repair, with the latter limited to 50% of the total study population) and randomized in a 1:1 fashion to treatment with GSK1278863 (300 milligrams [loading dose] followed by 100 milligrams [mg]/day x 4 days) or placebo starting prior to planned repair, through postoperative day 3. The duration of participation in this study is expected to be approximately 4 to 8 weeks from screening to follow-up.
To clarify whether amnesia after treatment of anterior communicating aneurysm (ACoA)is related to infarcts caused by occlusion or damage of the perforating artery of the ACoA, we used 3.0-T 3D high resolution MR imaging to identify and localize infarcts in patients with amnesia following treatment of ACoA aneurysm.
The principal objective is to assess the general health status and the sexual health status of women with Rokitansky syndrome having received a surgical or non surgical treatment. The secondary purpose is to assess the anatomical aspect and the quality of sexual life. To search a correlation between the anatomical result, the general and sexual quality of life. To compare the different techniques of medical follow-up in terms of anatomic results, general quality of life, sexual quality of life, complications and morbidities. To evaluate social inclusion of these women with their family situation, social and professional category and their job. At the same time, we propose an evaluation with a psychologist to study the impact of the announcement of the diagnosis. This impact study is conducted at a distance from diagnosis.
Abdominal aortic aneurysm (AAA) is an abnormal dilatation of the aorta in the abdomen secondary to hypertension and atherosclerosis. Surgical treatment of AAA is increasingly being replaced by endovascular aneurysm repair (EVAR) using stent-grafts (SGs). However, the efficacy of this less invasive approach is often jeopardized by the incidence of persistent flow within the aneurysm, called endoleaks leading to aneurysm rupture if not properly detected and treated. Hence, a life long annual CT-scan surveillance is required increasing the cost of EVAR, exposing the patient to ionizing radiation and nephrotoxic contrast agent. The goal of this project is to adapt and test a new ultrasound technology called ultrasound elastography to improve patient follow-up after EVAR and ultimately avoid the use of CT-scans. This technique measures the deformation of the tissue secondary to blood pressure variation (quasi-static elastography) or to a shear wave generated by the ultrasound probe (dynamic elastography). The investigators will optimize 2 approaches to generate elastic maps of the AAA. One approach will be a quasi-static elastography (QSE-LSME) technique developed by our team giving an estimation of the deformation (strain) of the different components of the AAA by the blood pressure. The second is a dynamic elastography (SSWI) technique that will provide information on the elastic property of the AAA components.
Various medical therapies have been proposed to prevent abdominal aortic aneurysm expansion. However, there have been very few randomized clinical trials to support use of any of these treatments. Several animal studies and observational reports suggest that ARBs can be useful in reducing abdominal aortic aneurysm (AAA) growth. However, so far, ARBs have not been evaluated in a randomized clinical trial. Therefore, the purpose of the study is to evaluate the effect of valsartan, an ARB, on annual growth rate in comparison with atenolol, a beta-blocker. Our hypothesis is that valsartan is superior to atenolol in the suppression of the aneurysm growth at 12 months. The BASE trial is designed as a investigator-initiated, multi-center, randomized controlled open-label trial. Patients with small AAA (aorta diameter <5cm) will be randomized 1:1 either to valsartan or to atenolol group. Randomization will be stratified by the AAA size (max. diameter >4 cm or ≤4 cm). Patients will receive either valsartan (daily dose 80 mg or more) or atenolol (daily dose 50 mg or more) for 12 months. A CT scan will measure the maximal diameter of AAA at baseline and 12 months. The annual growth of AAA will be compared between the valsartan and the atenolol group.
The purpose of this study is to investigate the prevalence of abdominal aortic aneurysms (AAA) among male patients with coronary artery disease (CAD) verified in coronary angiography. Ethiology of AAA is known to be common with atherosclerotic arterial diseases (coronary artery disease, peripheral artery disease and carotid artery disease), so the hypothesis is that AAA should be more common among these CAD patients, thus making screening of these patients (for AAA) more cost-efficient. Study will be carried out as a multi-center prospective screening study. Data will be collected in North Karelia Central Hospital, Kuopio University Hospital and Tampere University Hospital. Data consists of 200 consecutive coronary angiography patients in each hospital, resulting in 600 patients in total. All male patients with diagnosed CAD will be recruited for the study and screened for AAA with ultrasound. Nevertheless, patients with previously known AAA will be excluded from the study.
The proposed PIVOTAL study will examine a panel of platelet/coagulation activity markers during the perioperative period. The goal is to develop a clinically useful assessment of platelet/coagulation activity for risk stratification that may ultimately serve as a target for therapeutic intervention. This study will enroll 200 patients with peripheral artery disease undergoing vascular surgery. PIVOTAL is funded by American Heart Association and is scheduled to begin enrollment in July 2013 for approximately two years.
Phase 1/2a Multicenter, Controlled, Randomized, Open Label, Dose Escalation, Safety, Tolerability, and Pharmacokinetic Study Comparing EG-1962 and Nimodipine in Patients with Aneurysmal Subarachnoid Hemorrhage
This is a pilot study designed to validate our methods of recruitment, screening and data collection in the community. The project will help to establish the feasibility of the study design to lay the groundwork for a potentially larger study. The final study will allow us to estimate the incidence and prevalence of abdominal aortic aneurysm (AAA), carotid artery stenosis, and peripheral artery disease (PAD) in different geographic areas in a large urban setting, as well as determine patient access to healthcare and treatment for vascular disease as related to geographic and racial differences.
