Filter by:Background: Open repair remains the gold standard for fit patients with complex AAA. In the past decade, an evolution of devices, design, components, and delivery systems expanded the application of EVAR in these challenging anatomies. Fenestrated stent-grafts are now commercially available for the repair of complex AAA in the United States and Europe. Initial reports have demonstrated a high technical success rate, low renal dysfunction rate, and low morbidity and mortality, with promising short- and long-term results. Other reports have shown excessive morbidity and mortality with fenestrated EVAR (FEVAR). Studies comparing endovascular and open repair are sparse, especially when it concerns long-term outcomes. There are till nowadays only two propensity score-matched studies, one showing worse short-term and another long-term clinical outcome for fenestrated-branched EVAR (F/BEVAR) over open surgical repair (OSR). Aim: The aim of this study will be to compare F/BEVAR versus open AAA repair on short- and long-term clinical outcomes for the treatment of juxta- and pararenal AAA. Methodology: This is a prospective cohort study from the four high-volume AAA repair centers: Belgrade/Serbia, Bologna/Italy, Milan/Italy, Dijklander/Netherland, Amsterdam/Netherland, and Helsinki/Finland. Data will be collected on demographics, baseline comorbidities, AAA parameters (diameter and localization), laboratory values, intra-, and postoperative data. Follow-up examinations (clinical visits and color duplex ultrasonography, CT scans) will be performed 1, 6, and 12 months after the intervention, and annually thereafter. Propensity score analysis will be performed by matching open repair patients to endovascularly treated controlling for demographics and baseline comorbidities. Endpoints: Primary endpoints are all-cause mortality and the freedom from aortic-related reintervention. The secondary endpoint is the 30-day complication rate, especially acute kidney injury according to the RIFLE criteria.
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.
The EASY post-market clinical follow-up study is undertaken to demonstrate safety and clinical performance of the E-tegra Stent Graft System used in endovascular treatment of infrarenal aortic aneurysm.
This study aims to determine the relationship between the cross-sectional aortic area/patient height ratio (indexed aortic area) and absolute aortic diameter in proximal thoracic aortic aneurysms associated with a bicuspid valve. This will shed light on whether aneurysms with smaller diameters than those recommended for surgical intervention by guidelines are still at risk of aortic complications attending an abnormally high indexed aortic area.
This randomized controlled trial aim to determine the impact on renal function after treatment for infrarenal abdominal aortic aneurysm (AAA) with stentgrafts either with active supra- or infrarenal fixation.
To determine the safety and efficacy of IMPEDE-FX Embolization Plug and/or IMPEDE-FX Rapid Fill to fill an abdominal aortic aneurysm (AAA) sac outside of an endovascular aneurysm repair (EVAR) stent graft.
A prospective, single-center, non-blind, non-randomized safety and feasibility study of the hybrid repair of thoracic aortic pathologies requiring repair of the aortic arch proximal to the origin of innominate artery.
The primary objective of this study is to examine the safety and effectiveness of physician-modified endovascular grafts (PMEGs) for endovascular repair of complex aortic pathology in high-risk patients. The study is divided into three study arms based on the subject's aortic pathology: (1) Complex abdominal aortic aneurysm (AAA); (2) Thoracoabdominal aortic aneurysm; and (3) Aortic dissection.
This study is the First in Man Study of WeFlow-JAAA Stent Graft System manufactured by EndoNom Medtech(Hangzhou) Co., Ltd.
A First in man study to evaluate the safety and efficacy of thoracoabdominal aortic stent system for endovascular treatment of thoracoabdominal aortic aneurysms.
