Overview
Arteriovenous graft infection (AVGI) is a significant complication in hemodialysis patients, contributing to access failure, morbidity (3-35%), and mortality rates up to 12% 1.Diagnosis
Clinical signs include fever, pain, swelling, and purulent discharge around the graft site 1.
Imaging studies such as ultrasound and Doppler can help identify signs of infection like increased flow turbulence or fluid collections 1.
Blood cultures are essential for identifying the causative organism 1.
Dialysis access-related bloodstream infection (DRI) criteria may be used for grading severity 1.Management
First-line treatment: Intravenous antibiotics targeting the identified pathogen, often broad-spectrum initially (e.g., vancomycin, piperacillin-tazobactam) 1.
Surgical intervention: Total graft excision (TGE) is recommended over partial graft excision (PGE) to reduce recurrent infection risk 1.
Reoperation: Higher likelihood with PGE compared to TGE 1.
Close monitoring: Regular follow-up to assess for signs of recurrent infection or graft-related complications 1.Special Populations
No specific recommendations: The provided abstracts do not cover special populations such as pregnancy, pediatrics, elderly, or specific comorbidities 1.Key Recommendations
Opt for total graft excision (TGE) over partial graft excision (PGE) in managing AVGI to decrease recurrent infection rates (Evidence: Strong 1).
Initiate broad-spectrum intravenous antibiotics promptly, tailored based on culture and sensitivity results (Evidence: Moderate 1).
Implement rigorous postoperative monitoring to promptly identify and manage recurrent infections or graft-related issues (Evidence: Expert opinion 1).References
