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.

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.

NCT07224230
This single-arm FDA-monitored protocol intends to broaden endovascular device applicability using physician-modifications in patients who A) Have anatomical conditions not amenable to endovascular repair using currently marketed grafts in the United States. B) Are at high risk for open surgical repair. C) Are high-risk subjects with previously placed endovascular devices and have developed failure of their previous devices. The use of physician-modified endografts aims to shift the seal zone proximally above the celiac artery in order to treat their complex or thoracoabdominal aneurysms in a minimally invasive fashion. These patients are considered too high risk to survive open surgical repair and do not meet anatomic criteria for the Gore Thoracoabdominal Multi Branch Endoprosthesis, which is currently the only FDA approved device in the US to treat these aneurysms. The primary objective is to evaluate safety and effective of physician modified endografts in the treatment of thorax-abdominal aneurysms and complex aortic aneurysms. For primary safety endpoints, mortality and major adverse events (MAE) will be analyzed at 30 days or in hospitalization (if this exceeds 30 days). Primary endpoints include the following: 1. Mortality related to primary aortic disease 2. Aneurysm rupture 3. All cause mortality For primary effectiveness endpoints, treatment success will be analyzed as the proportion of patients to achieve treatment success at 12 months. Treatment success is defined by a composite endpoint, which includes all of the following criteria: Technical success (defined as successful delivery and deployment of the physician modified endograft with perseveration of those branch vessels intended to be preserved, freedom from type I or type III endoleak, freedom from stent graft migration, freedom from aneurysm enlargement \>5mm, freedom from aneurysm rupture or conversion to open repair. Secondary objectives of the study include assessment of individual safety and effectiveness endpoints as follows: technical success, procedure success, mortality, major adverse events - specifically renal, cardia, pulmonary, gastrointestinal, and neurologic. Each endpoint will be analyzed separately. Secondary endpoints will be individually analyzed at 4-8 weeks, 6 months, and annually at 1,2,3,4, and 5 years. Secondary endpoints to be analyzed are the following: 1. Evidence of Aortic Disease Progression: Monitoring for aneurysm growth \> 5 mm from baseline measurements. 2. Device Failure: Evaluation of device performance, including migration \> 10 mm, device degradation, and loss of device integrity. 3. Endoleaks: Monitoring for the occurrence and classification of endoleaks as outlined in the clinical outcome definitions. 4. Secondary Interventions: Description and analysis of secondary interventions aimed at treating branch vessel stenosis, occlusion, or embolization. 5. Significant Lifestyle-Limiting or Disabling Complications: Assessment and reporting of complications resulting in significant impairment of daily life, such as stroke-induced paralysis (paraplegia). 6. Cardiac Dysfunction: Monitoring and analysis of cardiac events, including myocardial infarction, congestive heart failure, and cardiac ischemia requiring intervention. 7. Renal Events: Evaluation of renal complications, including the need for dialysis, deterioration of renal function, and renal failure. 8. Mesenteric Events: Description and classification of mesenteric complications, such as ischemia and the need for surgical resection. 9. Respiratory Events: Monitoring for respiratory complications, including respiratory failure and prolonged intubation Secondary endpoints will be individually analyzed at 4-8 weeks, 6 months, and annually at 1,2,3,4, and 5 years

No comparison group was present.
NCT07184723
Symptomatic non-ruptured abdominal aortic aneurysms (snrAAA) remain a clinical challenge due to limited evidence and heterogeneous definitions and management strategies. Unlike ruptured AAAs, snrAAA lack large-scale population-based studies, primarily due to inconsistent application of standardised medical classifications (e.g., ICD-10) and international variability in definitions, diagnostic approaches, and treatment protocols. Optimal diagnostic pathways, preoperative risk assessments, and treatment strategies remain poorly defined, with minimal guidance from existing guidelines. This study aims to conduct a multinational cross-sectional online survey with optional retrospective validation to assess current opinions on an institutional scale regarding the definition and management of patients with snrAAA in Europe. All European vascular centres offering elective and emergency AAA repair are eligible to participate. Multiple survey entries from the same institution are not allowed. Centres are also invited to participate in a retrospective observational validation, reporting diagnostic and therapeutic details of their last five snrAAA cases.

NCT05976711
An abdominal aortic aneurysm (AAA) is a pathological dilatation of the aorta in the belly which can rupture leading to bleeding within the belly. To prevent rupture elective surgery can be performed. Endovascular repair (EVAR) is a surgical intervention whereby a stent is inserted into the AAA to prevent it from further growth and rupture. Standard AAA management has several drawbacks. To start: maximum AAA diameter is used to determine upon timing of elective repair but is imprecise in predicting the risk of rupture resulting in an unmet clinical need. Secondly, EVAR outcome and complication occurrence remain unpredictable due to poor prediction ability of computed tomography (CT) and ultrasound (US) utilised in the follow-up protocol. Lastly, patients and physicians are being repeatedly exposed to cumulative radiation toxicity. All these drawbacks could be solved by trading the standard imaging modalities by magnetic resonance imaging (MRI). Within the MARVY, advanced MRI techniques are used to find out if standard imaging techniques could be replaced by MRI in three phases of the AAA management (surveillance, surgery planning and post-operative follow-up). The two most important MRI techniques that will be used are 4D flow MRI and dynamic contrast enhanced (DCE) MRI which give respectively information about the blood flow within the AAA and perfusion of the aortic wall.
