The study is non-randomized, multicenter international safety, performance and clinical benefit outcome assessment of ACP-T20 to treat patients with isolated type II endoleak in the presence of a growing AAA-sac following an EVAR procedure more than 6 months ago.
The purpose of this study is to evaluate the reduction of the Abdominal Aortic Aneurysm (AAA) annual growth rate in patients who switch from smoking cigarettes to using IQOS as compared to patients who continue to smoke cigarettes. The study also aims to provide context to the scale of reduction in the growth rate, by comparing the AAA annual growth rates for continuing to smoke and switching to IQOS with the AAA annual growth rate in smokers who had stopped smoking. The study will further evaluate the effects of switching to IQOS on co-morbidities observed in AAA patients that are related to smoking as well as to assess the effects on relevant clinical risk endpoints linked to smoking related diseases.
Retrospective data have shown that active sac management, as applied in EVAS, reduces the incidence of the post-implant syndrome. All-cause and cardiac mortality at one-year seems to be lower after EVAS when compared to EVAR. Ongoing, low grade, inflammation could differ between techniques and induce cardiac damage. This study is designed to establish whether EVAS results in a reduced post-operative inflammatory response during the first year after surgery, compared to EVAR as assessed by trends in circulating inflammatory cytokine concentration. Study design: International prospective, comparative, explorative study. Study population: Patients scheduled to undergo infra-renal EVAR with a polyester endograft or EVAS for an infrarenal aortic aneurysm. This is an explorative study and therefore only patients who would normally receive a suitable device as part of standard treatment at the participating institutes will be recruited. Blood samples will be taken at specified time points before and after surgery. Main study parameters/endpoints: The difference in early post-operative and long term inflammatory response between EVAS and EVAR, measured by the incidence of the post-implant syndrome. To investigate the incidence of the post-implant syndrome, the rise in CRP, WBC and circulating cytokines, at specified time points up to 12 months after surgery and the change in aortic thrombus volume and its relationship with the inflammatory response, measured by cytokines' concentrations.
The BIOMArCS-AAA study aims to investigate the associations of (temporal patterns of) blood biomarkers with aneurysm growth in patients with abdominal aortic aneurysm (AAA), with particular attention to biomarkers that have demonstrated prognostic value for adverse disease outcomes in coronary artery disease and biomarkers for the main genetic pathways associated with AAA.
A prospective, multi-centre, objective performance criteria clinical trial to evaluate the safety and efficacy of Abdominal Aortic Aneurysm Stent Graft System manufactured by Lifetech Scientific (Shenzhen) Co., LTD. for the infrarenal abdominal aortic aneurysm.
A prospective randomized, double blind, placebo-controlled, safety and efficacy study of metformin as add-on therapy in abdominal aortic aneurysm (AAA) OBJECTIVES Primary Objective - To demonstrate treatment efficacy of metformin in AAA in comparison to placebo or active comparator, as measured by growth of the AAA maximum diameter at 12 months Secondary Objectives - To asses inflammatory cytokines and parameters of neutrophil activation in AAA in response to metformin treatment by glucose - insulin - IL-6 - markers of neutrophil activation (MPO, elastase, NGAL)
This study evaluates a novel noninvasive method to dynamically monitor the effect of abdominal aortic aneurysm (AAA) and endovascular treatment of AAA (EVAR) on arterial pulse wave
Patients with abdominal aortic aneurysms (AAA) suitable for endovascular aortic repair (EVAR) with Treovance were eligible to participate. Main inclusion criteria were: age 18-85 years; infrarenal AAA without significant infrarenal or distal iliac landing neck calcification or thrombus formation; infrarenal or distal iliac landing neck size requirements specified in the instructions for use. Main exclusion criteria: dissection/ruptured aneurysm or prior AAA endovascular or surgical repair. The primary endpoints were standard EVAR criteria.
Blood supply to the sigmoid colon during open abdominal aortic aneurysm (AAA) repair is at risk. Ischemia of the sigmoid colon after AAA repair is potentially devastative. No reliable measures to prevent it are available and the underlying mechanisms are poorly understood. The aim of this study is to describe intraoperative perfusion patterns of the sigmoid colon during open AAA repair and their potential impact on postoperative outcome.
Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.
