The value of computed tomography angiography in evaluating autogenous arteriovenous fistula dysfunction in haemodialysis patients

INTRODUCTION: This study aimed to evaluate the diagnostic performance and clinical value of computed tomography angiography (CTA) in assessing postoperative restenosis of arteriovenous fistulas (AVFs), and to analyse the correlation between stenosis severity and post-intervention outcomes. METHODS: This single-centre retrospective study included 102 patients (63% male; mean age: 59.2 years) with dysfunctional upper-limb autogenous arteriovenous fistulas undergoing haemodialysis, retrospectively analysed from April 2024 to February 2025. Computed tomography angiography-derived morphological parameters and prognostic data were collected. RESULTS: = 0.029). CONCLUSION: Computed tomography angiography effectively assesses AVF stenosis and guides interventions, though its long-term prognostic value warrants further study.
