Which of the following can represent a complication related to access site management?

Thrombosis is a significant complication associated with access site management, particularly in patients undergoing dialysis. It refers to the formation of a blood clot within the vascular access, which can obstruct blood flow and hinder the effectiveness of the dialysis process. When access sites, such as arteriovenous (AV) fistulas or grafts, are not managed properly, inflammation or damage to the vessel can occur, increasing the risk of thrombus formation. This can lead to decreased dialysis efficiency and the potential need for surgical intervention to restore access.

Frequent needle use, low access pressure, and excess fluid retention, while they might indicate issues related to access management or general patient conditions, do not specifically align with the direct complications of access site integrity and function in the same critical manner as thrombosis does. Thus, the identification of thrombosis underscores its importance in ensuring the effectiveness and longevity of dialysis access sites.
