Role of Collateral Vein Occlusion in Autologous Dysfunctional Hemodialysis Fistulas
An autologous arterial-venous fistula is the most desirable vascular access for end-stage renal disease (ESRD) patients who are dependent on hemodialysis. [1] Autologous arterial-venous fistulas have a lower risk of thrombosis and infection, and have shown to have a longer patency as well. [1] Kidney Dialysis Outline and Quality Initiative (KDOQI) guidelines mandate that 50% of all new hemodialysis accesses and 40% of all hemodialysis accesses be autologous arterial-venous fistulas.
Introduction ::: The purpose of this study is to compare the tissue incorporation of a novel fenestrated and non-fenestrated crosslinked porcine dermal matrix (CPDM) (CollaMend™, Davol Inc., Warwick, RI) in a porcine model of ventral hernia repair.
