C C Fistulas, also called Cimino-Brescia fistulas, are a type of arteriovenous fistula created surgically for hemodialysis access in patients suffering from end-stage renal disease (ESRD). An arteriovenous fistula is an abnormal connection between an artery and a vein, allowing for an improved blood flow by redirecting blood from the artery to the vein.
C C Fistulas are typically constructed using a native blood vessel, often the radial artery located in the forearm, and an adjacent vein, commonly the cephalic vein. The procedure involves surgically connecting the artery and vein, allowing the arterial blood to flow directly into the vein. This creates a higher blood flow and pressure in the vein, enabling easier and more efficient insertion of hemodialysis needles during dialysis treatment.
These fistulas are preferred over other types of vascular access because they have greater longevity, lower complication rates, and reduced risk of infection and thrombosis. The name "C C Fistulas" is derived from the technique's inventors, Dr. Dominick Cimino and Dr. James Brescia.
However, despite their benefits, C C Fistulas may have some limitations, such as inadequate maturation or failure to develop properly, which can lead to complications. Monitoring and regular assessment of the fistula's function and patency are essential to maintain its effectiveness and detect any signs of dysfunction.
Overall, C C Fistulas are a widely accepted and commonly used surgical procedure for establishing long-term and reliable vascular access in ESRD patients undergoing hemodialysis.
