RODRIGUEZ-ASENSIO, Javier Hernán et al. Endovascular repair of arteriovenous fistulas by angioplasty with drug eluting stent. Angiología [online]. 2024, vol.76, n.3, pp.189-193.  Epub 16-Oct-2024. ISSN 1695-2987.  https://dx.doi.org/10.20960/angiologia.00576.

Ten cases of patients with terminal chronic renal failure (CRF) on hemodialysis (HD) every three weeks are described: 6 women and 4 men between 40 and 70 years of age; with vascular accesses (VA) in the upper limbs: 4 brachial-axillary prosthetic grafts (AVG) and 6 native accesses; 4 of them with brachiocephalic (BC) arteriovenous fistula (AVF) and 2 transposed brachiobasilic (BB) AVF. The 10 cases with dynamic dysfunctions of their accesses, evidenced by the recirculation values and an inadequate index of the amount of urea eliminated in one session and the volume of urea distribution in a patient that coincides with the total body water (Kt/V), not reaching dialysis goals. The accesses presented elevated venous pressure (PV), puncture difficulties, or pump collapse with a drop in arterial pressure (Qb). Angiography showed severe stenosis in all accesses, which were resolved by implanting a drug eluting stent (DES). Patency at 6 months was 100 %.
