NCT ID: NCT04875429 Recruiting - Clinical trials for Aortic Aneurysm, Abdominal

Zenith® Fenestrated+ Clinical Study

Start date: December 8, 2023
Phase: N/A
Study type: Interventional

The Zenith® Fenestrated+ Endovascular Graft Clinical Study will assess the safety and effectiveness of the Zenith® Fenestrated+ Endovascular Graft (ZFEN+) in combination with the BeGraft Balloon-Expandable FEVAR Bridging Stent Graft System (BeGraft) and Unibody2 for the treatment of patients with aortic aneurysms involving one or more of the major visceral arteries.

NCT ID: NCT04773223 Recruiting - Clinical trials for Juxtarenal Aortic Aneurysm

Comparison of Outcomes of Complex Abdominal Aortic Aneurysm Treatment

Start date: January 1, 2011
Phase:
Study type: Observational

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.

NCT ID: NCT04524247 Recruiting - Frailty Syndrome Clinical Trials

Frailty and Physician Modified Fenestrated Endograft for Thoracoabdominal Aortic Pathologies

Start date: February 23, 2021
Phase: N/A
Study type: Interventional

The primary objective of this single arm, prospective feasibility study, Impact of Frailty on Clinical Outcomes of Patients Treated for Thoracoabdominal and Complex Abdominal Aortic Aneurysms with Physician-Modified Fenestrated and Branched Stent Grafts, is to assess the use of the physician-modified fenestrated/branched endografts to repair thoracoabdominal and complex aortic aneurysms in subjects having appropriate anatomy, at high risks for open repairs. The primary intent of the study is to assess safety and preliminary effectiveness of the device acutely (i.e., treatment success and technical success), at 30 days (i.e., the rate of major adverse events (MAE)) and at 3 months, 6 months, 12 months, and annually to 5 years (i.e., the proportion of treatment group subjects that achieve and maintain treatment success). Additionally, this study will assess the degree of patient frailty before and after the aneurysm repair, as well as the association between the preoperative baseline frailty and clinical outcomes detailed above. This will help improve subject selection in identification of high risk patients who would not only suffer poor clinical outcomes, but also experience decline in their functional status.
