NCT06658730
An observational, prospective multi-regional post-market registry collecting mid- and long-term data to assess outcomes through ten years of follow-up for subjects treated with GORE® TAG® Conformable Thoracic Stent Graft with ACTIVE CONTROL System as a part of routine clinical practice. This post-market registry for the GORE® TAG® Conformable Thoracic Stent Graft with ACTIVE CONTROL System (CTAG w/AC) is intended to demonstrate that thoracic endovascular aortic repair (TEVAR) for lesions of the descending thoracic aorta continues to be a suitable treatment option for appropriately selected patients.

NCT02266719
The purpose of this study is to assess the clinical outcomes and radiation of the use of off-the-shelf and custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal, thoracoabdominal and arch aortic aneurysms in patients having appropriate anatomy. The study consists of three cohorts. The first 2 cohorts are the continuation of the current IDE study. The first cohort is aimed to assess the use of custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal and type IV thoracoabdominal aortic aneurysms in standard and high-risk patients having appropriate anatomy (Fenestrated-CMD cohort). The second cohort (Type I-III thoracoabdominal cohort) includes standard and high-risk patients with type I- III thoracoabdominal aneurysms that require the use of branched/fenestrated CMDs, or, in selected cases, the Zenith Thoracoabdominal Branch (Zenith® t-Branch™) device. Finally, the third cohort (the Arch cohort) will include 25 high-risk patients with aortic arch aneurysms treated by patient-specific stent-grafts with one to three inner branches or a scallop
NCT06029660

NCT00583817
The purpose of this study is to assess the role endovascular therapy to treat aortic disease involving the ascending aorta, the aortic arch, and the visceral segment of the aorta (or thoracoabdominal aorta)
NCT07548099
This research study is being conducted to test how an imaging drug called 64Cu-DOTA-ECL1i can be used to image an abdominal aortic aneurysm. 64Cu-DOTA-ECL1i is a drug used with an imaging test called a PET/CT (Positron Emission Tomography/Computed Tomography). The aim is to collect data using a new imaging drug called 64Cu-DOTA-ECL1i that may be able to create images of inflammation in the aorta, which is thought to be important in how aneurysms grow and develop and to understand how consistent these scans are across time and what might affect the inflammation.
NCT06969729

NCT07529275
fenCo is a European multicentre, prospective study to evaluate the use of the iCover covered stents as bridging stents for reno-visceral target vessel during fEVAR for the treatment of complex abdominal aortic aneurysms.
NCT07518251
The study is a multicenter, two-arm, open-label, randomized, parallel-controlled trial, which plans to enroll 236 participants diagnosed with TAAA from 4 hospitals in China. All patients receive TAAAR procedure and are randomized to control group (LHB) and experimental group (fCPB) in the ratio of 1:1. After a 1-year follow-up, the validity and safety of the different cardiopulmonary bypass for TAAAR is evaluated via the incidence of major adverse events including surgical mortality, RRT, stroke, and SCI, as well as intraoperative blood product transfusion volume, mechanical ventilation, and early mortality.
NCT07005141
The goal of this clinical trial is to evaluate the safety, performance, and Preliminary effectiveness of the iHub endoprosthesis system in treating iliac artery aneurysms in adult patients requiring endovascular repair. The study population includes both male and female adults over 18 years of age who meet the inclusion criteria for endovascular treatment of iliac artery aneurysms. The main questions it aims to answer are: Is the iHub stent-graft system safe for use in patients with iliac artery aneurysms? Does the iHub system demonstrate adequate technical performance and sustained patency over a 12-month follow-up period? Participants will undergo a minimally invasive endovascular procedure to implant the iHub endoprosthesis system. The device is designed to preserve internal iliac artery flow while excluding the aneurysmal segment. Participants will: Undergo pre-screening evaluations including clinical examination, laboratory tests, and imaging (CT angiography and ultrasound). Undergo endovascular implantation of the iHub device. Attend follow-up visits at 30, 90, 180, and 360 days post-implant to assess clinical outcomes and device performance.
NCT07438327
This study will test how well an artificial intelligence (AI) software called Aorta AIM measures the size of the aorta (the body's main blood vessel) from CT scans. The aorta can become enlarged over time, which may lead to serious health problems. Doctors need to measure the aorta accurately to monitor patients and decide on treatment. Currently, doctors measure the aorta manually on CT scans, which takes time and can vary between different doctors. Aorta AIM is designed to measure the aorta automatically and consistently. In this study, researchers will compare Aorta AIM's measurements to those made by experienced radiologists or cardiologists (doctors who specialize in reading medical images). The study will use CT scans that have already been taken as part of routine medical care - no additional scans or procedures are needed. The study will include approximately 250 participants across multiple hospitals in Brazil and the United States. Participants will be adults who have had a chest or abdominal CT scan that shows their aorta. The main goals are to: * Check if Aorta AIM measures the aorta as accurately as radiologists * See if Aorta AIM can help doctors work more efficiently * Evaluate if the software works well in different hospital settings and with different types of patients This research may help improve how doctors monitor aortic disease and make treatment decisions in the future. There are no risks to participants since the study only uses existing medical images.
NCT07476196
Objective To pragmatically collect and analyze patient-level clinical, procedural, and outcome data from participating centers in Italy and Poland on the use of the PERCUTEK Tycheseal™ stent-graft system for the endovascular repair of abdominal aortic aneurysms. The study aims to generate high-quality, real-world evidence on the technical success, safety, and mid-term outcomes of the device. Study Design This is a pragmatic, observational, multicenter physician-initiated registry that will collect patient-level data for all eligible patients undergoing PERCUTEK Tycheseal™ device implantation. Each site will enter data into a standardized paper case report form (CRF), including demographic, anatomical, procedural, and follow-up variables. Sites will be expected to comply with data entry timelines and quality control checks. The total projected enrollment is 120-200 patients across all sites over an expected 18 month inclusion period. The target enrollment is 120-200 patients across all participating sites.
NCT07475260
This is a national multicenter study with 25 patients with a complex AAA undergoing endovascular repair with the Fenestrated TREO™ stent graft. ECG and respiratory-gated CT scans will be performed pre-operatively, at discharge, after 6 months, and after 12 months follow up. If stent movement is still present in after 12 months, then another scan will be taken at 24 months. To include respiratory gated with the ECG-gated, patients will undergo ECG-gated CT scan during an inspiration breath-hold as well as an expiration breath-hold. This double gated CT scans will allow us to analyse the movement of the stent graft caused by the cardiac cycle and respiratory cycle. The duration of this study is 2.5 years.
