GOMEZ LOPEZ, Victoria Eugenia et al. Analysis of puncture of coated intravascular prostheses after salvage of arteriovenous fistula, after 12 months of experience. Enferm Nefrol [online]. 2017, vol.20, n.3, pp.247-251. ISSN 2255-3517.

Patients and method:

Twenty patients, with VIABAHN(r) implanted, were studied for pseudoaneurysms with thrombosis, ulcers in the puncture sites, failure of angioplasty or restenosis in less than 6 months. Parameters of AVF, primary and secondary patency (6 and 12 months), presence of complications and control of prosthesis deterioration by phlebography at 3 and 6 months were studied. For the puncture, a period of 4 weeks was expected.


A period of 15 ± 9.4 months was analyzed. The mean of the functional parameters of the AVF during hemodialysis was: blood flow rate: 362.5 ± 43.3 ml / min, Arterial Pressure: -209.5 ± 35.6 mmHg, Venous Pressure: 215.8 ± 34.5 mmHg, Kt 55 ± 5.4 l and recirculation 12.7 ± 3.7%. At 6 months, 66% (95% CI: 54-77) of the patients had primary permeability and 77% (95% CI 67-87) had secondary permeability. At 12 months 38% (IC 95% 24-52) primary permeability and 76% (IC 95% 66-87) secondary permeability. No adverse events related to the puncture, nor radiologically objectified deterioration in prostheses were observed. There was an episode of infection requiring removal of the prosthesis.


The VIABAHN(r) coated vascular prosthesis is effective and safe in the rescue of stented and / or thrombosed native AVFs, as it provides excellent dialysis parameters and high primary and secondary permeability, without repeated puncture associated with complications.
