Filter by: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.
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 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.
The Diagnosis of a thoracic Aortic Aneruysms usually made when imaging an abdominal aortic aneurysm which has reached threshold or as an incidental finding during a chest scan by computed tomography (CT) or magnetic resonance imaging (MRI). However, these imaging modalities are expensive, involve radiation exposure and can cause anaphylaxis and other allergic reaction from the contract agents used. In addition CT scans are contraindicated for those who have: allergic reactions to the contrast, radioactive iodine treatment for thyroid disease, metformin use, and chronic or acutely worsening renal disease. Ultrasound is a non-invasive imaging modality that is cheaper than the methods currently used for TAA detection and surveillance. Echocardiography is limited in assessing the TAA as it is not sensitive to image beyond the proximal ascending aorta which is why it is currently not used for screening or surveillance. A pilot study found that ultrasound has the potential to be used as a diagnostic modality for thoracic aortic aneurysms and may have a role in surveillance in patients for whom CT scanning is contraindicated. They found that the sensitivity and specificity of detecting TAA was 100% and 70% for a threshold of 35 mm, and 84% and 90% for a threshold of 40 mm. However, further validation of this methodology is required for it to be considered as a method of diagnosis and surveillance for this patient group. This study was only carried out by one experienced sonographer so it important to repeat this study to see if other sonographers are able to obtain the necessary views. The main purpose of this study is to validate the protocol used by pilot study to assess whether thoracic aortic aneurysms can be detected and measured accurately using ultrasound. There are two main objectives of this study: 1. Can ultrasound be used to detect thoracic aortic aneurysms? 2. Can ultrasound be used to accurately measure thoracic aortic aneurysms? If the results of this study show that ultrasound has high sensitivity and specificity for detecting thoracic aortic aneurysms, it could lead to a thoracic aorta screening programme.
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.
Lung surgery, open aortic surgery, TEVAR, and EVAR are major operations that carry a higher incidence of perioperative mortality and complications compare to other surgery. The study of the incidence of mortality and complications will help the hospital to benchmark with the others. Also the study of the risk factors of mortality and major complications will help to improve the patients' outcomes.
Prospective, randomized, multi-center study designed to evaluate the outcomes of commercially available contemporary EVAR in a real-world population. Patients will be randomized into two device cohorts and compared across the primary endpoints. Patients will be followed procedurally to discharge, at 1, 6, 12 months and annually through to 5 years (total follow-up commitment).
