Filter by:Principles= Prevention of incision hernias by primary closure of mid line laparotomies with the best-evidenced suture techniques. Background: Surgical practice of abdominal wall closure continues to rely largely on tradition rather than high-quality level I evidence. Incisional hernia after laparotomy for treatment of abdominal aortic aneurysm (AAA) has a high incidence. At this moment the best results in a prospective randomised clinical trial considering incision hernia rates and wound infections, have been reported by the surgeons from the Sundsvall clinic in Sweden. Their technique using a suture to wound length ratio of at least 4/1 and using many small stitches will be described in the protocol as the "Principles Technique". We want to explore if these results can indeed prevent incision hernias significantly if implemented with training and tutoring. Methodology:Vascular surgeons,who are not using the principles yet, but show an interest to learn the Principles, will be asked to monitor a cohort of AAA patients using their current sutures and surgical techniques. Some of the vascular surgeons will undergo training and if wanted, proctoring during the first procedures using the Principles. A cohort of 120 AAA patients will be closed according to the Principles and monitored. The results of these 120 patients will be compared to the control group consisting of patients closed with the conventional technique by non--‐trained surgeons. Primary endpoint:The incidence of incision hernias at 12 months will be determined by clinical examination. Data management and ownership: The data will be collected on a paper form and will be introduced is a database (SPSS Statistics, IBM) from which statistical analysis will be made.
This is a prospective observational cohort study that will collect data from the point of referral through to secondary care, aiming for 3 years median follow-up (range 1-5 years). The data collected will allow estimation of the success of any intervention (in terms of reducing rate of aneurysm growth, rupture or dissection) as well as estimation of the risks associated with the three procedures. Clinical outcomes in the three treatment groups will be described. Aims We aim to answer the following questions: 1. Without procedural intervention for chronic thoracic aortic aneurysm (CTAA), what is the risk of aneurysm growth, dissection, rupture, permanent neurological injury or death? What is the effect on quality of life (QoL)? 2. If a patient has endovascular stent grafting (ESG) or open surgical repair (OSR), what is the risk of growth, dissection, rupture, permanent neurological injury or death? 3. How does QoL change from pre- to post intervention? 4. Can aneurysm or patient related predictors of good/poor treatment outcomes be determined? 5. What is the most cost-effective strategy in: 1. Patients eligible for either ESG or OSR? 2. Patients eligible for either ESG or best medical therapy (BMT)? 3. Patients eligible for either watchful waiting (WW) or intervention (ESG/ OSR)? 6. What further research is required? What would be the most important research to pursue?
The purpose of this clinical trial is to assess and evaluate the safety and efficacy of the Treovance Stent-Graft with Navitel Delivery System in subjects with Abdominal Aortic Aneurysms (AAA).
This study was designed to assess the safety, tolerability and efficacy of ACZ885 on aneurysmal growth rate in subjects with abdominal aortic aneurysms (AAA). The purpose of the study was to provide data to enable decisions regarding the further development of ACZ885 for subjects with abdominal aortic aneurysms. The design of this study addressed the primary objective of evaluating the change in aneurysmal size in subjects with AAA as a result of treatment with ACZ885.
The purpose of this clinical research study is the design of a novel modular hybrid system extracorporeal circulation circuit for open heart procedures that could easily be converted from a closed to a semi-closed circuit according to the indication. This could expand the potential of minimal extracorporeal circulation and could ultimately become the new standard circuit in performing every type of cardiac surgery.
The primary objective of the study is to evaluate the acute safety of deploying and implanting the Altura Endograft in the treatment of AAA in subjects who are candidates for endovascular repair. Secondary objectives are to evaluate the acute and longer-term safety and performance of the Altura Endograft through 5 years.
This post-market study is approved by the US FDA to evaluate the long-term safety and performance of the Zenith® Fenestrated AAA Endovascular Graft.
Complex aortic aneurysms involving major branches have been difficult endovascularly. The primary purposes of this study is to evaluate the safety, feasibility, and efficacy of multiple overlapping uncovered stents in treating aortic aneurysm while preserving major visceral branches, including the celiac artery (CA), superior mesenteric artery (SMA) and renal artery (RA).
The Post-Approval Study (PAS) will evaluate the "real world" data on the Ovation™/Ovation Prime™ Abdominal Stent Graft System along with the long-term data collected from the IDE cohort to monitor the long-term safety and effectiveness of the device.
This study is being conducted to evaluate the safety and effectiveness of the Progel Vascular Sealant for use in vascular reconstructions to achieve adjunctive hemostasis by mechanically sealing areas of leakage.
