This systematic review and meta-analysis evaluated factors affecting patency after percutaneous transluminal angioplasty (PTA) for autogenous arteriovenous fistulae in hemodialysis patients, analyzing 52 studies with 6,407 participants. Key findings indicate that diabetes, lesion length >2 cm, and previous interventions significantly increase the risk of primary patency failure, with an odds ratio of 3.13 for previous interventions.
Key findings
- Diabetes increases the risk of primary patency failure with an odds ratio of 1.02.
- Lesion length >2 cm is associated with an odds ratio of 2.87 for primary patency failure.
- High post-PTA flow is protective against patency loss.
- Drug-coated balloons outperform conventional angioplasty in maintaining patency.
Why it matters
Understanding the factors influencing AVF patency after PTA can help clinicians identify at-risk patients and tailor interventions to improve outcomes. This knowledge is crucial for optimizing hemodialysis access management.
