Blood Vessel Prosthesis

Constitution of a prospective multicentric observational database to study vascular infections, both native, especially aortitis, and vascular graft and endograft infections. Clinical and paraclinical data on medical, surgical, anesthetic and intensive care management will be collected in order to better characterize these infections

A functioning dialysis vascular access is critical to the delivery of lifesaving hemodialysis. Arteriovenous graft (AVG) is a surgically created vascular access used for hemodialysis in patients with end-stage renal disease. AVG thrombosis due to underlying flow-limiting stenosis of the graft vein junction and outflow veins is a common complication. Thrombosed AVG can be treated with thrombolysis combined with percutaneous transluminal angioplasty with good immediate success rates. However, the mid-to-long term patency rates following angioplasty have been suboptimal. Sirolimus drug-coated balloon has been shown to be safe and effective in the salvage of thrombosed arteriovenous graft. The investigators hypothesize that sirolimus drug-coated balloon is non-inferior to stent graft in maintaining the patency of thrombosed AVG that is successfully salvaged. This study is conducted to compare the 6-month access circuit primary patency of thrombosed AVG treated with sirolimus drug-coated balloon versus stent graft.
