Active clinical trials for "Aortic Aneurysm"

The purpose of this study is to evaluate the procedural and clinical benefits of patient specific pre-procedure rehearsal for operators with various experience levels as a tool for optimizing Endovascular Aneurysm Repair (EVAR) procedures.

IgG4 Related Disease is a multi-systemic fibroenophilic disease that includes a basket of recently discovered medical conditions. The properties that bind them are: lesions similar to tumors in the mixed organs, lymphoplasms filtrate enriched with plasma IgG4 positive cells, storiform fibrosis, and often, but not always, a high level of IgG4 in the serum. This disease has been on the rise for the past two decades and since its recognition in 2001 there has been impressive progress in understanding its various manifestations, so that today almost every body system can be involved. One of the conditions associated with this disease is oritis / periortitis and aneurysms

The sudy purpose is to investigate efficacy and safety of percutaneous endovascular aortic aneurysm repair using INCRAFT stent graft for Korean patients with abdominal aortic aneurysm. This study is designed as an investigator-initiated, multi-center, single-arm, prospective registry study. A total of 100 patients who meet all inclusion criteria, but none of exclusion criteria will be enrolled after the implantation of INCRAFT stent graft. The primary efficacy outcome is technical success defined as successful deployment of the stent-graft with no type I/III endoleak, unintentional coverage of visceral aortic branches or internal iliac arteries at the end of the procedure, and with successful removal of the delivery system. The primary safety outcome is major vascular complications at 30 days including. The study subjects will be followed for 12 months.

Total endovascular repair of the aortic arch represents a promising option for patients ineligible to open surgery. Custom-made design of stent-grafts (SG), such as the Terumo Aortic® RelayBranch device (DB), requires complex preoperative measures. Accurate SG deployment is required to avoid intraoperative or postoperative complications, which is extremely challenging in the aortic arch. In that context, our aim is to develop a computational tool able to predict SG deployment in such highly complex situations. Four patient-specific cases will be performed with complete deployment of the DB and its bridging stents in aneurysmal aortic arch. Deviations of our simulation predictions from actual stent positions will be estimated based on post-operative scan and a sensitivity analysis will be performed to assess the effects of material parameters. If good agreement between simulation and reality is obtained, numerical simulations will show their ability to successfully predict the DB deployment in complex anatomy. The results will emphasize the potential of computational simulations to assist practitioners in planning and performing complex and secure interventions.

Prospecrtive study including 20-30 randomized patients treated by open repair because of an TAAA larger than 55 mm During the surgery, a heart lung machine is applied for distal perfusion during aortic cross clamping to enable distal organ perfusion. Regardless an intensive inflammatory reaction is a well known effect after reperfusion, leading to a uncontrolled inflammation during th first days after surgery. This may be associated to bad outcome and decreased survival rates. By the application of a intraoperative cytokine and DAMP filter this negative ffect could be reduced, resulting in a better outcome after surgery.

This pilot study aims to quantitatively characterize the stresses and forces on an implanted endograft during the cardiac cycle in patients scheduled for standard endograft follow-up. The developed techniques will be applied in future studies for characterizing and comparing the currently commercially available endografts so as to gain insight into the mechanisms underlying potential endograft failure. In addition, to assist in developing endografts with long-term durability and functioning characteristics for the benefit of the patient

The purpose of this study is to compare acute technical outcomes of the Talent AAA Stent Graft system versus Cook Zenith Endograft at two high volume institutions, Albany Medical Center and St. Peter's Hospital in Albany, NY. The investigators are comparing the two devices as part of the evolution of endovascular repair (EVAR) for AAAs. The Zenith AAA Endovascular Graft received FDA approval on May 23, 2003, the Talent Abdominal Stent Graft System on April 15, 2008.

Deep learning applied to plain abdominal radiographic surveillance after Endovascular Aneurysm Repair (EVAR) of Abdominal Aortic Aneurysm (AAA).

Minimally invasive aortic valve (AV) surgery has become widely accepted alternative to standard sternotomy. Despite possible reduction in morbidity, this approach is not routinely performed for aortic surgery. Evidence exists, however, on safety of this approach together with promising results regarding its long-term durability. The MIRAGE Registry is aimed to collect and analyse the data from multiple aortic excellence centres and to analyse them in numerous clinical scenarios.

Aorto-iliac aneurysms with involvement of the iliac bifurcation or hypogastric artery aneurysms constitute only 20% of all aneurysmal pathology of the abdominal aorta. As it is a rare pathology, in order to carry out a comprehensive study of the results, it is necessary to carry out multicenter studies to collect a considerable number of cases. One of the most widely used devices worldwide is the GORE® EXCLUDER® Iliac Branch Endoprosthesis, CE marked since 2013, this stent consists of two components: the iliac branch stent and the hypogastric component (HGB), for its joint use there are instructions for use in relation to the anatomical characteristics of the patient in order to be used. Currently, there are other devices that can be used as a hypogastric component when the patient's anatomy does not allow the use of HGB, one of them is: GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis, CE marked since 2017. This study is designed to evaluate the efficacy and safety of devices with iliac branches for the treatment of aorto-iliac aneurysms that affect the bifurcation of common iliacs, with the use of these devices, as well as to determine the quality of life of patients after their implantation.
