Active clinical trials for "Aneurysm"

Purpose of the study is the evaluation of the applicability of the percutaneous technique through double Proglide and Pre-Close Technique to the treatment of complex aortic aneurysms with thoracic endoprosthesis (TEVAR), fenestrated or branched (F / B-EVAR) in which patient-related factors, the devices used or the procedure, could affect the performance.

The purpose of this study is to evaluate whether there is an increased risk of achilles tendon rupture (ATR), retinal detachment (RD) or aortic aneurysm and dissection (AAD) following exposure to fluoroquinolone (FQ) or other antibiotics (amoxicillin, azithromycin, trimethoprim and trimethroprim/sulfamethoxazole) or febrile illness not treated with antibiotics, using a study design that minimizes the impact of confounders not usually captured in health services databases such as heredity or smoking.

Objective Complex aortic pathology has been revolutionized with the use of hybrid prostheses such as the Thoraflex® Hybrid Frozen Elephant Trunk (FET). The aim of this study was to evaluate the midterm results of secondary extension of the FET by thoracic endovascular aortic repair (TEVAR). Few data are present in the literature regarding the outcomes of this secondary treatment. The investigators perform a prospective study between 2015 and 2022 in a tertiary aortic center on all consecutive patients having undergone TEVAR after FET implantation. The TEVAR endograft covered most of the 10 cm FET module with 2 to 4 mm oversizing. All patients were monitored by computerized angiography (CTA) at 6-month and yearly thereafter. The aim of this study was the feasibility of theses secondary connexion and the mid term outcomes of the endovascular treatment.

The aim was to determine, within the patient enrolled in three controlled prospective studies, INNOVATION, INSPIRATION and INSIGHT (Sponsor: Cordis, A Cardinal Health Company) studies which are preoperative and postoperative anatomical risk factors associated to limb occlusion. In the three studies the total number of enrolled patients was 400, of whom 134 enrolled in the US

The overall aim is to determine the frequency by which women and men with intact abdominal aortic aneurysms (AAA) are treated with elective surgery at three vascular outpatient clinics in Europe, and to investigate whether the reasons to refrain from elective surgery differ between the sexes.

The goal of this observational study is to assess the role of the whole exome sequencing (WES) application in patients with giant coronary artery ectasia (CAE) with a high-risk of genetic background. The main question it aims to answer are: the assessment of role of WES in CAE the detection of novel pathogenic mutations associated with CAE development

The aim of the study is to evaluate the outcomes of the preloaded stent-graft design (PLD) in the routine treatment of para-renal and thoraco-abdominal aneurysms. Results and postoperative events are reported in accordance with the current reporting standards for endovascular aortic repair prepared and revised by the Ad Hoc Committee for Standardized Reporting Practices in Vascular Surgery of The Society for Vascular Surgery/American Association for Vascular Surgery. The Registry will include approximately 300 patients treated from January 2015 to May 2021 (retrospective arm) and June 2021 to June 2023 (perspective arm) for the routine treatment of para-renal and thoraco-abdominal aneurysms. To reach 300 patients, the enrollments can be extended until June 2026.

Fibromuscular dysplasia (FMD) is localized structural defects in the arterial wall, whose innate or acquired character is still unknown. This segmental non atheromatous injury, leads to stenosis of the arteries of small and medium caliber. Renal arteries are the most commonly affected with 60-75% of total fibrodysplasia. Three histological subtypes have been described: intimal, medial and peri-medial. They are not mutually exclusive and can be observed in the same patient. This is a rare blood disease, occurring in children and young adults. In this young population with long life expectancy, these aneurysmal lesion are associated with 10% risk of rupture. To date, no data have shown in the literature that FMD is link to genetic causes, or if there is specific histopathologic lesions for non-atherosclerotic renal artery aneurysms. To answer these questions, Cardiovascular Surgery Unit of the University Hospital of Saint-Etienne, French national reference center for renal artery surgery, in association with the Reference Center for Rare Vascular Disease in Paris, designed the first study for pathological and genetic characteristics of dysplastic renal artery aneurysms in young patients.

The PRESERVE-Zenith® Iliac Branch System Clinical Study is a clinical trial to collect confirmatory safety and effectiveness data on the Zenith® Branch Endovascular Graft-Iliac Bifurcation System. This system is made up of two devices: the Zenith® Branch Endovascular Graft-Iliac Bifurcation and the ConnectSX™ covered stent in the treatment of aorto-iliac and iliac aneurysms

The purpose of this study is to evaluate by non-invasive methods the change in central hemodynamics and arterial stiffness produced by grafts and endografts after abdominal aortic aneurysm repair. Our main goal is to measure the changes in: Augmentation index, central blood pressure, pulse wave analysis, pulse wave velocity.
