- W3159420570 abstract "Patients with functioning renal allografts may need ligation of pre-existing hemodialysis conduits. Chronic immunosuppression for renal allografts may adversely affect wound healing and perioperative complications following these procedures. We sought to analyze outcomes following elective ligation and resection of symptomatic arteriovenous (AV) access in immunosuppressed patients with renal allografts no longer requiring dialysis at a high-volume renal transplant hospital.We retrospectively reviewed procedure codes for hemodialysis access resection and revision from 2014-2020 at a single academic tertiary care hospital. Patients who underwent complete or subtotal dialysis access resection with a functioning renal allograft were included for analysis of preoperative, operative, and postoperative outcomes. We performed descriptive statistics, and student's t-test using Microsoft Excel.Thirty-four patients met inclusion criteria. The majority were male, 56%, and the most common causes of renal failure were hypertension and diabetes, respectively. Ligation and resection of proximal upper extremity access was performed in 68%. The mean operative time was 126 minutes with pain being the most common indication for intervention. Four patients required arterial reconstruction. Mean postoperative follow-up was 13 months. Arm pain and swelling resolved in 100% and 88% of patients following AV access resection, respectively. No impairment in mean postoperative glomerular filtration rates were noted. One patient required hemodialysis and died three months after fistula resection following complications from treatment of a newly diagnosed neuroendocrine tumor and subsequent fungemia, CONCLUSION: Elective operative resection of symptomatic AV access may be performed safely in immunosuppressed patients with functioning renal transplants. The risk of allograft impairment and/or failure as a result of AV access resection in our series was low. Elective ligation and resection can be achieved with low mortality, excellent symptomatic relief, and few wound complications despite chronic immunosuppression." @default.
