The current Society for Vascular Surgery practice guidelines recommend carotid revascularization for asymptomatic disease in patients with at least a 3-year life expectancy and stenosis >60% when the expected perioperative stroke and death rate is <3%. Based on this recommendation, it was previously determined that asymptomatic patients who require dialysis would not meet the perioperative stroke and death thresholds nor the long-term survival benchmarks to justify carotid surgery. To determine whether carotid surgery for patients requiring dialysis is appropriate, the present study compared the perioperative outcomes after carotid revascularization for dialysis-dependent patients relative to nondialysis patients in a contemporary, national cohort.

The targeted vascular module from the American College of Surgeons National Surgical Quality Improvement Program was queried to identify patients who undergone carotid endarterectomy or carotid artery stenting for asymptomatic carotid disease from 2011 to 2018. The cohort was categorized as requiring or not requiring dialysis. Multivariable analyses were used to assess the independent associations of the estimated glomerular filtration rate and dialysis dependence with the stroke/death rate.
