The Importance of Maintaining Flow through Hemodialysis Fistulas

Stent placement Albuquerque

Approximately 25,000 patients in the United States receive hemodialysis (HD) three times per week to combat end-stage renal disease (ESRD). Each patient uses an implanted fistula—a short-term surgical procedure that’s used to connect the vein in the arm to an artery in the neck or chest—to allow dialysis fluid to flow through their body while they sit comfortably at home and watch TV or sleep. When properly maintained, fistulas can be used indefinitely as long as there are no blockages or other complications.

Introduction

Patients with dialysis fistulas have unique needs. The flow through the fistula must be maintained above a certain level to allow adequate hemodialysis. The fistulas can be monitored with Doppler and color-flow ultrasound to determine if there is a leak or if there is an inadequate flow in the fistula. If a low flow or a leak is detected, stent placement may be indicated.

Doppler Monitoring

Hemodialysis fistulas can be monitored with Doppler and color-flow ultrasound to determine if there is a decrease in blood flow. If the flow decreases, patients may need to have the device changed or undergo a percutaneous endovascular stent placement in Albuquerque.

Ultrasound Monitoring

Ultrasound is used to monitor the flow through a dialysis fistula. The fistula can be monitored with Doppler and color-flow ultrasound to determine if it is appropriate for hemodialysis. If the fistula cannot be adequately maintained, the doctor may need to place a stent in order to maintain enough flow.

Patient Education Tips

Patients with dialysis fistulas have unique needs. The flow through the fistula must be maintained above a certain level to allow adequate hemodialysis. The fistulas can be monitored with Doppler and color-flow ultrasound to determine if the flow is sufficient, and a stent can be placed in the access site if needed. If you are experiencing symptoms such as swelling or infection from your hemodialysis catheter, contact your nephrologist for assistance.

Daily Dialysis Procedures

Stent placement Albuquerque is a procedure in which a tube or stent is placed inside the fistula to help maintain the flow. Stenting a patient’s fistula can help it heal and may prevent infection. The length of time the stent needs to be left in varies by location and individual condition. They are usually removed by a urologist, but some clinics will ask for a nurse to remove them at regular intervals.
