Filter by:To assess the expression of miRNA in patients with TAA, AAA in aneurysmatic tissue and to compare this expression with the healthy tissue in the same patient. In the same cohort, to asses the presence of miRNA in plasma and to compare with the control group. Over the period of three years,to follow subjects in order to assess if the presence of certain miRNAs speeds up or slows down the progression of disease. In patients with intracranial aneurysms to detect miRNA in plasma especially in patients with familial occurrence.
The objective of this clinical investigation is to evaluate the safety and technical success of the Basecamp Vascular controllable directional GECKO guidewire when used to facilitate endovascular access to the targeted vessel in order to treat the vascular lesion.
Introduction: Contrast induced nephropathy (CIN) is a major inconvenience in the use of iodinated contrast media (ICM) and it is associated with a significant increase in morbimortality and cost of hospitalization. Remote ischemic preconditioning (RIPC) is a non-invasive and cost-effective tissular protection technique that has proven beneficial in decreasing renal insult in patients receiving intravascular contrast. Aim: The primary outcome of this study is to evaluate the impact of RIPC on the incidence of CIN in patients undergoing endovascular aneurysm repair.Material and Methods: Patients suffering from aortic aneurysm were recruited prior to the administration of iodinated contrast media. Randomization was used to assign patients into the control/RIPC groups. Biochemical parameters determined renal function before and after surgery in immediate (24-72 hours) and at 30 days' follow-up.
This clinical study will capture clinical data specific to the performance and safety of the LeMaitre® CARDIAL Dialine II. It is a retrospective, monocenter, post-market safety and performance study. Following the new MDR regulation, this study will allow the clinical data of the prosthesis to be completed in order to renew its CE marking.
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.
This is a retrospective cohort study of consecutive patients submitted to elective EVAR, between February/2009 and May/2019 in a single institution. Symptomatic or ruptured AAA, mycotic aneurysms, isolated iliac aneurysms and complex abdominal aortic repairs were excluded. The primary outcomes were freedom from secondary intervention and compliance with follow-up, defined as surveillance imaging performed within a periodicity no longer than 18 months.
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 treatment of aortic aneurysms is today based on different indicators (diameters, lengths, angles, volumes of the arteries) measured on CT scan images. Several indicators are time consuming and complicatated to measure. They demand training and practice. Nurea is developing a software for automatic measurement of these indicators, PRAEVAorta® 2, to facilitate and assist the physician in his clinical routine. The purpose of this study is to compare the analysis realised by the software PRAEVAorta® 2 with the analysis realised by the healthcare professional on retrospective CT scan images. Contrasted and non-contrasted, pre-operation or post-operation CT scans from 50 patients will be analysed. The main objectif is to validate the accuracy of the software by demonstrating its adequacy to the standard method of analysis. The second objectives are the following: - Evaluate the security of the software PRAEVAorta® 2 - Evaluate the unanticipated risks related to the use of the software - Validate the accessory PRAEVAorta® Web We make the following assumption : 90% of the patients show 90% of adequacy to the healthcare professional analysis
During the last 15 years, neuronavigation has become an essential neurosurgical tool for pursuing minimal invasiveness and safety. One drawback of such devices is the fact, that the neurosurgeon has to look away from the surgical field onto a dedicated workstation screen. Additionally, the operator is required to transfer this information from the "virtual" environment of the navigation system to the real surgical field - whereas the real patient may be fixated and positioned differently compared to the visualization on the screen. Mixed-reality may have the potential to support this, by merging data from the real environment with virtual information and vice-versa. In the context of surgical navigation, the main goal of mixed reality systems is to provide a real-time updated 3D virtual model of anatomical details, overlaid on the real surgical field. In this sense, the mixed reality is the process of enrichment of reality with additional virtual contents. This clinical investigation aims at the collecting of clinical data about the mixed-reality supported planning, the registration accuracy and overall precision of the navigation system and the clinical outcome.
The purpose of the registry is to compare the surgical and endovascular approaches to the treatment of thoracoabdominal aortic aneurysms.
