What is a common complication to monitor for after arteriovenous fistula placement?

Following the placement of an arteriovenous fistula, monitoring for thrombosis is crucial because this complication can hinder the effectiveness of the fistula for hemodialysis. Thrombosis occurs when a clot forms and obstructs blood flow, which can lead to inadequate access for treatment and potentially compromise renal function.

The risk of thrombosis arises due to the nature of the fistula, as it is created by connecting an artery and a vein, increasing blood flow to the vein. If the blood flow becomes turbulent or if there is insufficient vessel dilation, clots can easily form. Early recognition and intervention can prevent long-term complications associated with the ineffective use of the fistula.

While it is also important to watch for hemorrhage, infection, and hyperglycemia in patients with arteriovenous fistulas, thrombosis is particularly significant because it directly affects the functionality of the created access point for dialysis.
