Nationwide Observational Study on the Natural History of Haemodialysis Arteriovenous Access and Patient Survival after Thrombosis in France
Objectifs
The objectives of this study were to describe the natural history of the haemodialysis arteriovenous access (both arteriovenous grafts and arteriovenous fistulae) after thrombosis in routine practice, comparing surgical and endovascular approaches, in a nationwide French cohort. The following outcomes were assessed: the 1-month and 1-year patency, overall access abandonment, and 1-year and 5-year overall survival rates.
Conclusion
The straightforward message for clinicians and health-system planners is clear: after thrombosis, two in five accesses fail within a year and one in four are abandoned; initial endovascular management offers more favorable access and survival trajectories. Priorities include timely revascularization, equitable access to endovascular expertise, and standardized patency definitions for future research.
