Haemodialysis Access Surgery
Haemodialysis access surgery provides safe, adequate flow from the patient to the dialysis machine in kidney failure. Good access improves session efficiency and reduces complications.
1) AV fistula
Direct artery–vein anastomosis; preferred and most durable. Usually in the forearm. Venous wall maturation may need 4–8 weeks.
- Lower infection risk
- Better flow
- Less thrombosis tendency when anatomy is suitable
2) AV graft
When native vein is inadequate, a synthetic graft connects artery and vein; different durability and infection profile but may be usable sooner than a mature fistula.
3) Dialysis catheter
For urgent dialysis or as a bridge, a central line is placed. Fast access but higher infection and stenosis risk; use as short as possible.
Patient care
No blood draws from the fistula arm, avoid heavy lifting on that side, check pulse/thrill regularly and seek prompt review if flow drops.
