Primary
| Measure | Time frame |
|---|---|
| Flow in vascular access for hemodialysis measured by vascular Doppler ultrasound, presented in milliliters per minute, measured before, during and after surgery at 12 hours, 7 days, 30 days, 60 days and 90 days post-operatively.;Mortality using life table graphs measured after surgery at 12 hours, 7 days, 30 days, 60 days and 90 days postoperatively | — |
Secondary
| Measure | Time frame |
|---|---|
| Infection using clinical examination measured after surgery at 12 hours, 7 days, 30 days, 60 days and 90 days postoperatively;Thrombosis at 12 hours, 7 days, 30 days, 60 days and 90 days postoperativelyusing Doppler vascular ultrasound. ;Regional hemodynamic parameters that will be measure included peak systolic velocity (PSV cm/s), end-diastolic velocity (EDV cm/s), diameter (D mm), resistance index (RI) and blood flow (Q mL/min) at 12 hours, 7 days, 30 days, 60 days and 90 days postoperatively. | — |
