Abstract

Background: In Vietnam, it is estimated that about 8 million people have chronic kidney failure, of which stages III to V account for 3.1 - 3.6% [3]. Today, hemodialysis is a popular method in the world, as well as in Vietnam. This is a method of filtering blood by creating a circulation outside the body to remove waste and excess water through the filter through the following mechanisms: ultrafiltration, diffusion, and convection. Most patients need dialysis 12-18 hours/week and usually three times/week. Arteriovenous bypass surgery for routine dialysis in patients with end-stage chronic kidney failure is essential. Methods: Retrospective description of case series. Results: The study had a mean age of 55.5 ± 15.1 years; Females make up the majority, and lipid metabolism disorders, hypertension, and diabetes account for 97.9%, 94%, and 79.2% of the sample, respectively. The surgical location of the wrist between the radial artery and cephalic vein accounted for the majority, 50.6% of the sample. We often ligate the returning venous branch after AVF surgery, accounting for 91.5% of the sample. The technical success rate reached 96.2%. The complications recorded as surgical wound infection accounted for 7.7%; hematoma accounted for 6.4%; and embolism 1.7%. The rate of primary patency accounted for 82.3% of the sample. Mid-term complications include steal syndrome, accounting for 10.6%; Hand edema accounted for 5.1% of the sample. Conclusion: The mid-term results in vascular primary patency of AVF in patients with chronic renal failure are safe, effective, and have few complications.
