Filter by:The aim of this study is to investigate the effect of the implantation of an Ultrapro® Mesh as prevention of incisional hernia after elective open abdominal aortic aneurysm repair. According to the literature these patients have an increased risk for an incisional hernia. By the implantation of an artificial mesh into the abdominal wall during the first abdominal aortic aneurysm repair, the risk can be reduced dramatically. In small feasibility studies incisional hernia rates as low as 0% have been achieved. Patients scheduled for elective open abdominal aortic aneurysm repair will be randomized into two groups, one receiving an onlay mesh, the other conventional wound closure with sutures.
The primary endpoint is successful secondary endovascular treatment with the Talent Converter stent graft of subjects having received prior endovascular repair of infrarenal abdominal aortic or aortoiliac aneurysms using the Talent or AneuRx Bifurcated Stent Grafts, in which there is inadequate proximal fixation, seal, overlapping of modular components or unattainable contralateral limb cannulation. Treatment success is defined as a composite of successful vessel access, successful insertion of the delivery system, successful deployment of the Converter stent graft at the intended treatment site and absence of Type I endoleak at the 1 month follow-up visit.
The primary study objective, at this time, is to follow out to 5 years post implant the safety of already enrolled subjects who were treated with the UniFit Aorto-uni-iliac (AUI) Endoluminal Stent Graft (the "study device") for the repair of abdominal aortic aneurysms (AAAs).
The aorta is a large blood vessel that carries blood away from the heart to the organs in the rest of the body. An aneurysm is a weakening in the artery wall that will become a bulge in the aorta. If left untreated, this bulge may continue to grow larger and may rupture (break open) with fatal consequences. Abdominal aortic aneurysm (AAA) is a life-threatening lesion that has been treated in recent year via endovascular repair. The purpose of this study is to monitor the long term performance of the AneuRx Stent Graft Systems.
Conflicting results have been reported concerning the association of pseudoexfoliation syndrome (PXF) and abdominal aortic aneurysms (AAA). Schumacher et al. reported an association between AAA and PXF, with no consideration of grade. However, a later study did not confirm the association between AAA and PXF. The present study aimed at comparing the relative prevalence of PXF in patients suffering from AAA and in age-matched hypertensive patients.
The purpose of this study is to compare endovascular repair using any FDA approved Medtronic AAA Stent Graft System versus surveillance in subjects with smaller abdominal aortic aneurysms (AAA)(4-5CM), with respect to AAA rupture and AAA related deaths.
The main risk of aortic aneurysms is rupture that leads to a high risk of death. A preventive surgical treatment is thus needed. In order to reduce the morbidity and mortality associated with conventional surgery, an endovascular approach (insertion of an endovascular stent graft)is now widely favored. The main problem of this procedure is the occurrence of endoleaks (persistence of a communication between the aneurysm and the aorta). A new approach is proposed to prevent these endoleaks. The principle is to draw blood from the patient, separate the blood from the platelets, and reinject both platelet rich plasma (PRP) and autologous thrombin, in order to form a platelet gel (PRP + autologous thrombin). Before studying the efficacy of this technique, its safety of use and feasibility must be evaluated.
Aggressive intraoperative and postoperative management of blood glucose may substantially decrease perioperative cardiovascular and infectious complications in diabetic and non-diabetic patients undergoing vascular surgery. The purpose of this study is to compare the tight versus traditional blood glucose control in diabetics and non-diabetics undergoing vascular surgery in regard to their postoperative fatal and nonfatal cardiac outcomes, and the secondary effects such as rate of infections, overall morbidity and 30-day mortality.
Objective of the present study is to compare endovascular repair versus surveillance and, eventually delay treatment in patients with small abdominal aortic aneurysms (AAA), with respect to patient survival, AAA rupture and AAA related death risks.
