Aim:
To identify predictors of anatomical suitability for endovascular arteriovenous fistula (Endo-AVF) creation.
Background:
Endo-AVF requires specific anatomical criteria, but predictors of suitability remain poorly defined.
Method
We analysed data from 39 patients referred for endo AVF evaluation between October 2024 and April 2025. Age, gender, weight, diabetic and ischaemic heart disease (IHD) status were assessed as potential predictors of suitability.
Results:
Of 39 patients, 36 patients (92%) had undergone mapping and 29 (81% of mapped) were deemed suitable for Endo-AVF creation. The mapped cohort was predominantly male (75%), with diabetes in 47% and IHD in 22%. Suitability was similar for patients with and without diabetes (83% vs. 78%, p=0.72) and for females versus males (89 % vs 78 %; p = 0.65). IHD showed a non significant trend toward reduced suitability (63 % with IHD vs 86 % without; p = 0.18). Age and weight did not differ meaningfully between suitable and unsuitable groups (both p > 0.4).
Conclusion:
Approximately four-fifths of referred patients were anatomically suitable for Endo-AVF creation. Traditional clinical factors did not significantly predict suitability. A non-significant trend toward lower eligibility in patients with IHD was observed. This data warrants validation in larger cohorts in multi-centre studies.
