The surgical connection created to allow blood to flow between the patient's circulatory system and the dialysis machine during hemodialysis sessions.
Vascular access is the lifeline for hemodialysis patients. The three main types are: (1) Arteriovenous Fistula (AVF) — surgical connection between an artery and vein, considered the gold standard with lowest complication rates; (2) Arteriovenous Graft (AVG) — synthetic tube connecting artery to vein, used when native vessels are unsuitable; (3) Central Venous Catheter (CVC) — temporary or tunneled catheter, used for urgent dialysis or when AVF/AVG is not possible. Monitoring access function through flow rates, recirculation testing, and physical examination is critical to prevent thrombosis and infection.
A medical procedure that filters waste products, excess fluids, and toxins from the blood using a dialysis machine when the kidneys can no longer perform this function adequately.
A surgical connection between an artery and a vein, typically in the forearm, created to provide reliable vascular access for hemodialysis.
A flexible tube inserted into a large central vein (usually internal jugular) to provide temporary or permanent vascular access for hemodialysis when AV fistula or graft is unavailable.
The technique of inserting a needle into a vascular access to establish blood flow for hemodialysis, requiring specialized skills to prevent complications and preserve access longevity.
