Central vein stenosis- prevalence, clinical characteristics, outcome and its impact on dialysis access.

Central vein stenosis (CVS) is a complication primarily affecting chronic hemodialysis patients, frequently resulting in vascular access dysfunction and decreased dialysis efficacy. While CVS has a variable mortality rate, its impact on dialysis access is profound, including arm edema, facial swelling, and venous hypertension. We describe the prevalence, clinical presentation, and treatment outcomes of CVS for vascular access in hemodialysis patients.
