Filter by:The purpose of the registry is to compare the surgical and endovascular approaches to the treatment of thoracoabdominal aortic aneurysms.
The aim of the present study was to investigate outcomes of a propensity matched series of patients treated with F-BEVAR and open surgery repair for complex abdominal aortic aneurysm in two aortic high-volume centres.
The aim of present study is to evaluate intraoperative, peri-operative, and post-operative results in patients treated by the ALTO stent graft (Endologix Inc. Irvine, Calif) for elective Abdominal Aortic Aneurysm repair in a multicentric consecutive experience.
It is recognised that women are at greater risk of death, complications and longer hospital stay following intact abdominal aortic aneurysm (AAA) repair, and the reason for this is not yet established. This disparity in outcomes for women compared to men is also recognised in other forms of cardiovascular surgery, which raises the question of whether women and men are reacting differently to the stress of operative repair. This study aims to examine whether there are differences baseline stress markers and in the stress response to AAA repair between men and women. It will also examine whether markers of stress are associated with poor clinical outcomes and slower recovery (indicated by longer hospital stay). The study will take the form of an observational cohort study. It will not alter any of the treatment that men and women receive, but will monitor their stress levels using physiological markers (through ECG (electrocardiogram) monitoring using a non-invasive holter, biochemical markers using blood samples (which will be taken at the same time as routine testing, so as not to require further invasive procedures), and psychological testing, using short forms that the patient will be able to fill out independently at different stages of their recovery. Clinical data will be used to look for relevant factors (clinical history or medications) which may alter the stress markers we are observing, and to compare outcomes with markers of stress. Patients will be asked for their consent to share their data with the research team in order to participate in the study. It will be made clear that there will be no change in their clinical or operative management if they participate in the study and they will be able to withdraw consent for further participation at any time.
Advanced Endovascular repair of aneurysms and dissections involving thoraco-abdominal (type I-IV) and complex abdominal (juxta and para-renal) aorta is a ground-gaining procedure allowing favorable results in high surgical risk patients. The availability of iliac vessels navigation and the major role of lower leg perfusion in order to decrease the risk of spinal cord ischemia during these complex procedures, led to the development of devices with lower sheaths sizes and to the improvement of the technique with preloaded devices for visceral vessels in order to navigate in hostile anatomies or when an iliac access is not available. The aim of the study is to evaluate in a prospective single center observational setting, the outcomes, safety and efficacy of the modified preloaded system for renal arteries in fenestrated endografting in the routine treatment of paravisceral and thoraco-abdominal aortic pathologies.
The acute phase of the COVID-19 pandemic requires a redefinition of healthcare system to increase the number of available intensive care units for COVID-19 patients. This leads to the postponing of elective surgeries including the treatment of abdominal aortic aneurysm (AAA). The probabilistic rupture risk index (PRRI) recently showed its advantage over the diameter criterion in AAA rupture risk assessment. Its major improvement is in increased specificity and yet has the same sensitivity as the maximal diameter criterion. The objective of this study was to test the clinical applicability of the PRRI diagnostic method in a quasi-prospective observational patient cohort study.
The primary objective is to evaluate the safety and effectiveness of surgeon modified endografts for the treatment of pararenal and thoracoabdominal aortic pathology in patients who are not candidate for traditional open repair due to comorbid issues and their anatomy is not amenable to commercially available endografts.
The main objective of the CARE-ANEURYSM project is to evaluate inflammation and clotting abnormalities in patients with aneurysmal coronary artery disease in relation to patients with abdominal aortic aneurysm or coronary artery disease (acting as controls).
A prospective, multi-center, objective performance criteria clinical trial to evaluate the safety and efficacy of WeFlow-JAAA stent graft system manufactured by Hangzhou Endonom Medtech Co., Ltd. for the complex abdominal aortic aneurysm.
This is a Hellenic Registry including both retrospective and prospective subjects receiving the Ovation Alto™ Abdominal Stent Graft System ("Ovation Alto™ Abdominal Stent Graft System Post-Market Study") in the treatment of abdominal aortic aneurysms (AAA). The Ovation Alto™ Hellenic Registry is intended to expand the clinical knowledge base by collecting data on subjects treated with the Ovation Alto™ Abdominal Stent Graft System in actual clinical practice during the first post-operative year.
