- Classic signs of pain, erythema, swelling, d/c from infected access are often missing
Differential Diagnosis
AV Fistula Complications
- Clotting of AV fistula
- Infection of AV fistula
- Hemorrhage of AV fistula
- Vascular insufficiency from AV fistula
- AV fistula aneurysm/pseudoaneurysm
- High-output heart failure from AV fistula
Workup

- 4x higher colony count in catheter blood cx suggests catheter is source of bacteremia
Management
- Give vancomycin 1gm IV +/- gentamicin 100mg IV (if gram neg suspected)
