Patency of arteriovenous fistula for dialysis improbe with topical spraygel heparin

Vascular access for hemodialysis can be provided by a native arteriovenous fistula (AVF), a synthetic arteriovenous graft (AVG), or a central venous catheter. The mature, native fistula is considered the preferred type of vascular access. This study evaluates the results of a retrospective registry assessing topically applied heparin (added to antiplatelet therapy) efficacy in patients with newly created AVF.
