Background:

The incidence of chronic kidney disease is increasing and the native arteriovenous fistula (AVF) is the preferred access for renal replacement therapy due to its durability and low complication rate.

Objective:

To evaluate clinical characteristics and endovascular rescue treatment.

Method:

Observational, descriptive, cross-sectional and retrospective study, with data from patients from the Vascular Surgery Service of the Central Military Hospital who presented AVF dysfunction.

Results:

70.6% of the patients suffered from type 2 diabetes and hypertension. 64.7% had a history of having two or more central venous catheters. Isolated venous stenosis was the most common etiological feature (70.59%). Primary patency was maintained at 12 and 24 months (52.94%). The most common treatment applied was simple balloon angioplasty (76.47%) with a technical and clinical success of 100%.

Conclusion:

Isolated venous stenosis was the main cause of AVF dysfunction. Endovascular treatments were effective for AVF rescue, allowing post-procedure patency and functionality.
