PURPOSE To evaluate prospectively the safety and efficacy of totally percutaneous placement of abdominal and thoracic aortic endografts using the Prostar XL suture-mediated closure system. METHODS From January 2002 to January 2005, we attempted to insert percutaneously all bifurcated abdominal aortic and thoracic endografts. Consecutive patients (25 men,(More)
PURPOSE Dissatisfaction with conventional methods of treatment of infected infrarenal aortic prosthetic grafts and excellent long-term results reported by heart surgeons after allograft replacement for management of infections involving the ascending aorta have prompted us to investigate allograft replacement in the management of arterial infections. (More)
PURPOSE Chronic rejection of arterial allografts and xenografts results in arterial wall dilation and rupture, making them unsuitable for long-term arterial replacement in vascular surgery. In the arterial wall, as in other organs, the cells probably carry major antigenic determinants. Arterial wall cellular components can be removed by detergent treatment(More)
PURPOSE Prosthetic graft infection is an uncommon but life-threatening complication of descending thoracic/thoracoabdominal aortic aneurysmectomy. The purpose of this study was to assess the value of in situ arterial allografts in the management of this complication. METHODS From 1992 to 2000 we treated 11 consecutive patients with prosthetic graft(More)
Acquired abdominal aortic aneurysms are usually associated with a mural thrombus through which blood continues to flow. Some early data suggest that aneurysmal evolution correlates with the biological activity of the thrombus. Our hypothesis was therefore that the thrombus could adsorb blood components and store, release, and participate in the activation(More)
We conducted this retrospective study to determine the prevalence of giant cell arteritis (GCA) in patients exhibiting nonatherosclerotic upper and/or lower extremity arterial involvement and to evaluate the clinical features and long-term outcome of those patients.From January 1997 to March 2008, 36 consecutive patients in the Department of Internal(More)
INTRODUCTION Transplant arteriosclerosis is the main cause of long-term failure after cardiac transplantation. Vascular rejection is thought to be due to intimal proliferation occurring in response to arterial wall immune-mediated injury. A low molecular weight fucan (LMWF) compound, a sulfated polysaccharide, has been demonstrated to increase plasma levels(More)
One hundred femoropopliteal bypass procedures performed in 91 patients between October 1980 and January 1985 were randomly divided into two statistically comparable groups including 50 in situ vein grafts and 50 reversed vein grafts. The indication for bypass was chronic critical ischemia in 97% of cases. The lower anastomosis was made on the distal(More)
Arteriosclerotic intimal proliferation is one of the main long-term complications of organ transplantation. Low-molecular-weight, heparin-like molecules prevent myointimal proliferation in arterial wall injury and limit rejection in skin allografts. Cyclosporin limits rejection but has no major effect on intimal proliferation. Therefore, an experimental(More)
BACKGROUND Both humoral factors and apoptosis have been recently suggested to play a role in chronic allograft rejection. However, a link between alloantibodies and grafted cell apoptosis has never been proposed. Using the aortic allograft model in the rat, we have previously demonstrated the presence of IgG associated with the disappearance of donor(More)
