Active clinical trials for "Aortic Aneurysm"

Aortic arch repair surgery is a technically complex and challenging procedure to treat aortic pathologies. Despite advancements in perioperative care, detrimental neurological complications occur during or after surgery. The neurological complications increase the economic burden of healthcare, morbidity and quality of life for the patients, even if they survive. Stroke, for example, leads to an increase in healthcare and social care costs, requiring a subsequent lengthy rehabilitation. Milder neurological impairments include transient ischaemic attacks, confusion and delirium, necessitating longer intensive care and hospital stay. Currently applied cerebral monitoring modalities are electroencephalogram and cerebral oximetry. However, they are not specific enough to timely detect early cerebral ischaemia to prevent neurological complications. S100B protein and neuron-specific enolase are serum markers that reflect cerebral damage, however, their applicability in the hyperacute setting is limited. However, rapid measurements of glial fibrillary protein have paved new pathways to detect cerebral injury. Recent studies reveal more sensitive biomarkers of glucose, lactate, pyruvate, glutamate and glycerol. These biomarkers could potentially detect cerebral ischaemia on a near real-time basis using the microdialysis method. The aim of the project is to develop a bedside system for early detection of cerebral ischaemia on a near real-time basis during aortic arch surgery. Early detection of cerebral ischaemia could mandate more aggressive cerebral protection strategies by further optimisation of hypothermia and antegrade selective cerebral perfusion during surgery, and optimisation of blood pressure and oxygenation in the intensive care unit. Ultimately, early detection of cerebral ischemia during surgery will prevent disabling and costly neurological complications following surgery.

This multicenter, single-arm retrospective registry (chart review) is being conducted to confirm the clinical performance and safety of GORE-TEX® Vascular Grafts and GORE® PROPATEN® Vascular Graft throughout the device functional lifetime for each indication area.

Study Design This is a prospective, multicenter, non-randomized clinical study in patients presenting thoracic aortic pathologies. Following a baseline assessment, the implantation procedure will be performed according to the Instructions for Use and local routine practice. A follow-up visit will be performed 30 days, 6, 12,24 and 36 months after the implantation procedure. The investigator will perform assessments of the implantation procedure and device system and document adverse events (AE) and device deficiencies. Resources utilization and unit costs will be collected at index procedure and during follow-up. HRQoL is going to be investigated in this prospective study using the generic questionnaire EQ5D 5 levels, comparing pre- and postoperative scores. Study Objective The objective of the study is to evaluate the safety, performance and resource utilization associated with the use of GORE® TAG® Conformable Thoracic Stent Graft with ACTIVE CONTROL systems in humans having thoracic aortic pathologies. Safety will be evaluated considering mortality and morbidity variables (mainly focused on device related complications). Efficacy will be evaluated according to the variables related to the technical and clinical successes. In addition, resource utilization and associated costs will be collected prospectively with the objective to analyze differences in resource utilization between outcome groups, landing zone groups, disease severity groups, adverse event groups and case-mix groups. We will calculate the average marginal costs increase for complications when they occurred during TEVAR or surgical revascularization (e.g., paralysis, stroke, nerve injury, lymph damages, myocardial infarction, major bleeding event, respiratory complication). Resource utilization analysis is not going to be limited to the index procedure but will continue during follow-up. Subject Population: Elective and Urgent Thoracic aorta pathologies such as aneurysms, pseudoaneurysms, dissections, blunt thoracic aorta injury, penetrating ulcers and intramural hematoma. Planned number of patients: A total of 200 patients. Approx. 20 study centers in 2 European countries (15 in Italy and 5 in Spain) . A subgroup of 8centers will be selected for the micro-costing analysis (7 in Italy and one in Barcelona) Expected Time to Complete Enrollment: end of 2021 (18 months).

An abdominal aortic aneurysm is a condition where the major artery in the abdomen becomes larger than usual. Over time, as it continues to grow, the wall of the artery weakens and there is a risk that the artery can burst causing internal bleeding and death. Aortic aneurysms are fixed when they reach a certain size to prevent that outcome. The surgery to fix them is a major, high-risk surgery that is associated with a lot of complications and a slow recovery back to normal. The time between diagnosis and surgery is called the pre-operative period and is a key time to optimize a patient's health in order to ensure the best possible outcomes following surgery. This study will look at whether a multidisciplinary pre-operative program that involves exercise training, nutritional advice and supplementation, and psychosocial support will reduce complications following surgery. This program should decrease complications and speed up a patient's recovery back to normal after surgery. It is also a way for patients to take ownership of their disease and play an active role in their health care journey. The benefits from this program will go beyond the pre-operative time frame, as the habits and knowledge gained will improve their health over their lifetime. This study will also assess the economic impact and cost of a program like this.

The objective of the study is to collect real-world data on patient outcomes and evaluate the safety and performance of the Lifetech Ankura™ AAA Stent Graft System, Ankura™ Cuff Stent Graft System, Ankura™ AUI Stent Graft System and ZoeTrack™ Super Stiff Guidewire.

The main objective is to compare the mitochondrial dynamic between patients operated for aneurysm of ascending aorta or type A aortic dissection (AAD) or control group

Observational, prospective, cohort study to evaluate, by an opportunistic screening program based on vascular ultrasound, the prevalence and characteristics of Abdominal Aortic Aneurysm (AAA) and Popliteal Artery Aneurysm (PAA) in a female population as well as the prevalence and characteristics of PAA in male population.

The HERCULES trial is a Randomized controlled clinical trial designed to prospectively compare endosuture aneurysm repair (ESAR) to standard endovascular aneurysm repair (EVAR) clinical outcomes in treatment of infrarenal abdominal aortic aneurysm (AAA) in subjects having wide proximal aortic neck diameters (≥ 28mm and ≤ 32mm).
