TAPIA-GUDINO, Johnny A.; LARA-GONZALEZ, Viridiana R.; TORRES-MARTINEZ, Jorge A.  y  SERRANO-LOZANO, Julio A.. Results of angioplasty in the salvage of dysfunctional arteriovenous fistulas for hemodialysis. Rev. mex. angiol. [online]. 2021, vol.49, n.2, pp.51-56.  Epub 23-Ago-2021. ISSN 2696-130X.


In the salvage of dysfunctional internal arteriovenous fistulas (AVF), complete or sufficient blood flow restoration is the main goal.


To present results of the use of angioplasty with simple or medicated balloons without stent in the salvage of dysfunctional AVF.


Observational, retrospective study in patients with AVF dysfunction who underwent simple and medicated balloon angioplasty without a stent. Demographic data, comorbidities, changes in vein diameter before and after angioplasty, blood flow before and after angioplasty, residual stenosis, secondary patency time, and dysfunction rate were recorded.


Of 25 patients undergoing angioplasty, the mean age 63 ± 10 years (52% male), 24% had thrombosis, 76% stenosis. Mean residual stenosis was 12% at 6 months, 15 fistulas remained functional (60%) and 10 fistulas dysfunctioned (40%) (p = 0.030). Immediate postoperative complications were bleeding (8%) or surgical site infection (4%).


Simple or medicated balloon angioplasty results in a significant restoration of blood flow volume, facilitating the functionality of the AVF and is associated with a low frequency of complications.
