In these randomized, controlled trials, 130 patients undergoing peripheral artery bypass surgery, spinal surgery, arteriovenous graft construction or liver resection surgery had areas of intraoperative bleeding treated with gelatin sponges containing a solution of either rhThrombin or placebo.
This therapy has the advantage of being locally applied and could make a significant difference in arteriovenous graft failure rates, a major unmet medical problem.
The purpose of this study is to evaluate arteriovenous grafts and to compare the time to first intervention of the upper extremity arteriovenous graft to that of the anterior chest wall arteriovenous graft.
Predictors of arteriovenous graft patency after radiologic intervention in hemodialysis patients.
There are three different types of vascular access for hemodialysis: arteriovenous fistula, arteriovenous graft, and central venous catheters
Approximately 2 weeks postoperatively, edema was observed in the arm with the new arteriovenous graft (AVG).
These arteriovenous grafts (AVGs) had higher infection rates than AVFs, but the offsets were additional hemodialysis access options and prolonged chronic hemodialysis access (Gilliland, 2017).
The arteriovenous fistula is the preferred type of vascular access because of lower complication rates compared with synthetic arteriovenous grafts or central venous catheters.
Both of these guidelines recommend that an arteriovenous fistula not be cannulated before four weeks and that arteriovenous grafts not be cannulated before 14 days.
However, advances in the technology of vascular access are improving the quality of care for patients with ESRD, and several brands of synthetic grafts have appeared on the market to help improve the patency of arteriovenous grafts (AVGs).
