The risk of thrombosis of the fistula is significant because it directly affects the functionality of the access point used for dialysis. A fistula, which is created by surgically connecting an artery and a vein, serves as a reliable access point for blood removal and return during the dialysis process. However, the formation of a clot within the fistula can impede blood flow, making it difficult or impossible to perform dialysis effectively.

If thrombosis occurs, it may require further medical intervention such as thrombectomy, or potentially even surgical options to restore access. Maintaining the patency of the fistula is crucial, and healthcare providers closely monitor for signs of poor blood flow or insufficient dialysis effectiveness. Understanding this aspect of fistula management is vital for ensuring ongoing effective dialysis treatment. Other factors like infection and patient anxiety, while important, do not pose as immediate a risk to the dialysis process as thrombosis does.
