What does thrombosis refer to in the context of hemodialysis?

Thrombosis in the context of hemodialysis specifically refers to the formation of blood clots within the vascular system, particularly in the access where blood is drawn and returned during the dialysis process. This can occur in arteriovenous (AV) fistulas or grafts used for hemodialysis, leading to complications that can compromise the effectiveness of treatment.

Understanding thrombosis is crucial for healthcare providers involved in hemodialysis, as it can result in reduced blood flow, dialyzer clotting, and potentially a failure of the dialysis access site, necessitating interventions to restore patency or access planning. Recognizing the signs and risk factors for thrombosis allows for timely measures to prevent its occurrence, such as ensuring proper vascular access flow rates and monitoring for any changes in the access site. This understanding is integral to maintaining efficient hemodialysis processes and ensuring patient safety.
