What condition should be addressed when there is no blood flow in the vascular access?

When there is no blood flow in the vascular access, the condition that typically needs to be addressed is thrombosis. Thrombosis refers to the formation of a blood clot within the vascular access site, which can obstruct the flow of blood. This can lead to serious complications, as the access, whether it is a fistula or graft, serves as a crucial pathway for dialysis treatment.

In the case of thrombosis, the clot can completely block the access, preventing blood from being drawn for dialysis or returned after treatment. Recognizing and addressing this condition promptly is essential to restore adequate blood flow and maintain effective dialysis sessions.

The other conditions listed, while significant in their contexts, do not directly relate to the immediate concern of obstructed blood flow in the vascular access point. Hemorrhage involves excessive bleeding, hypoxia pertains to insufficient oxygen reaching tissues, and stenosis refers to narrowing of the vessel which can affect blood flow, but may not completely block it as thrombosis can.
