The study evaluated the heparin bioactive surface (hbs) non-medtronic device efficacy in the maintenance or re-establishment of hemodialysis.Outcomes were stent patency intended as primary circuit patency (pp), assisted primary patency (app), target lesion primary patency (tlpp) and secondary patency (sp).Once the lesion had been crossed, pre-dilatation with 2- or 3-mm diameter balloon catheter (pacific plus, medtronic, (b)(4)) was subsequently performed to allow the passage of the delivery system.If the obstruction segment was crossed by 0.014¿ guidewire, it was replaced by 0.018¿ guidewire.The 4 fr short introducer sheath was then changed for a short introducer sheath with profile ranged from 6 fr to 8 fr, depending on stent diameter that was selected according to the diameter of the adjacent normal reference vessel.If the lesion could not be crossed, a second retrograde access was required through the puncture of the venous outflow, slightly more proximal to the obstruction.It is reported that 37 patients underwent 50 stent graft placement.Repeat procedures were required in cases where hemodialysis access dysfunction was identified with a total of 88 repeat procedures being undertaken.Three complications occurred: minor complications included two access hematoma that were conservatively managed with no consequences on hemodialysis circuit.A single case of infection of avg by staphylococcus aureus occurred three months after the stent placement.One procedure was unsuccessful because the circuit thrombosis occurred two days after the stent placement and the hemodialysis access was abandoned.
