TAPIA-GUDINO, Johnny A.; LARA-GONZALEZ, Viridiana R.; TORRES-MARTINEZ, Jorge A. e 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. https://doi.org/10.24875/rma.21000011.
Background:
In the salvage of dysfunctional internal arteriovenous fistulas (AVF), complete or sufficient blood flow restoration is the main goal.
Objective:
To present results of the use of angioplasty with simple or medicated balloons without stent in the salvage of dysfunctional AVF.
Methodology:
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.
Results:
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%).
Conclusions:
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.
