What is a synthetic AV bridge graft used for in dialysis?

1. Long-term access for hemodialysis

2. Short-term renal function monitoring

3. IV medication administration

4. Bowel access for nutrition

The correct answer is: Long-term access for hemodialysis

A synthetic AV (arteriovenous) bridge graft is primarily used for long-term access for hemodialysis in patients with chronic kidney disease who require regular dialysis treatment. This type of graft is created by surgically connecting an artery to a vein using a synthetic material, allowing for efficient access to the bloodstream. This is crucial for hemodialysis, as the procedure needs reliable and durable vascular access to filter waste from the blood effectively. The synthetic graft provides a larger and more consistent blood flow compared to traditional fistulas, making it ideal for patients who may have limited options for direct vascular access. It is particularly beneficial for patients whose veins might not be suitable for a fistula due to previous medical conditions or failed attempts at creating a fistula. The other options focus on purposes that do not align with the function of an AV bridge graft. While the graft enhances hemodialysis access, it is not used for renal function monitoring or for administering IV medications, and it certainly does not serve as bowel access for nutrition. Each of these functions requires different types of vascular or medical interventions and does not involve the synthetic AV graft.
