Arteriovenous fistula infection

Due to fewer complication and longer survival rates, the native arteriovenous fistula is the preferred access for hemodialysis. Venous catheters are plagued by complications such as infection and thrombosis and often deliver relatively poor blood flow rates. [Pg.851]

Complications that can occur at the common femoral artery puncture site include formation of a hematoma, pseudoaneurysm, or arteriovenous fistula, dissection or thrombosis of the common femoral artery, and infection [53, 56]. Vessel perforation is even more unusual than arterial dissection but may be problematic in that it could either cause occlusion of the uterine artery prior to embolization or can cause bleeding from the perforated vessel which may itself require embolization as treatment (Fig. 10.4.4) [56],... [Pg.163]

In patients with vascular access, the probability of dialysis access-related infection is considerably less for patients with native arteriovenous fistulae than for those with synthetic grafts [36]. Postoperative wound infection as well as poor aseptic technique at dialysis may cause infection of the fistula silent infec-... [Pg.41]

Considerable morbidity exists when dealing with vascular access (VA) creation. Native arteriovenous fistulae (AVF) are the desired VA for patients on dialysis due to their comparably low morbidity and fairly good long-term patency. However, they are also at risk for nonmaturation, stenosis, thrombosis, infection, aneurysm formation, and steal syndrome [ 1 ]. Fistula success is dependent on the center of access creation. Hence, the vascular surgeon s skills and decisions are key [2]. Furthermore, success is also determined by preoperative, technical, and postoperative factors that will be discussed in this chapter (fig. 1). [Pg.135]

Hemodialysis (HD) catheter-associated bloodstream infections (BSls) are a type of CLABSI due to a central venous catheter (CVC) specifically designed for HD. In 2002, it was estimated that 50,000 CLABSIs occur in dialysis patients in the US annually. A more recent surveillance study found the rate of access-related BSIs to be 0.73 events per 100 patient-months [5]. Aside from catheters, patients in need of renal replacement therapy should eventually use arteriovenous fistula (AVF) or arteriovenous grafts (AVG) for HD, or alternatively, may receive peritoneal dialysis. All renal replacement therapies are associated with a risk of infection however, this risk varies with the method selected. Data from a CDC surveillance program display nicely how the type of access influences the BSI rate per 100 patient-months 0.5 (for AVFs), 0.9 (AVG), 4.2 (permanent CVCs), and an impressive 27.1 for temporary CVCs [6]. Another, more practi-... [Pg.217]
