Arteriovenous Fistula Creation for Dialysis at Sheikh Shakhbout Medical City
Overview of Arteriovenous Fistulas (AVF)
An arteriovenous fistula (AVF) is a surgical connection between an artery and a vein, primarily used to create reliable access for patients undergoing hemodialysis. This procedure is essential for individuals diagnosed with end-stage renal disease (ESRD) who require regular dialysis treatment. The AVF is considered the optimal choice for dialysis access due to its longevity and lower risk of complications compared to other methods.
Benefits of AV Fistula Creation
Key Advantages
- Longevity: AV fistulas typically function longer than other access types, reducing the need for replacement.
- Lower Infection Risk: Unlike synthetic grafts, AV fistulas have a significantly lower risk of infection.
- Enhanced Blood Flow: The procedure increases blood flow through the vein, which is crucial for effective dialysis.
- Minimally Invasive: The creation of an AV fistula is usually performed as an outpatient procedure under local anesthesia, allowing for a quick recovery.
Procedure for AV Fistula Creation
Step-by-Step Process
- Preoperative Evaluation: A thorough assessment of the patient's blood vessels is conducted, often using ultrasound and angiography to ensure they are suitable for AVF creation.
- Surgical Procedure:
- The vascular specialist administers local anesthesia to the chosen site, typically in the arm.
- A small incision is made to access the selected artery and vein.
- The artery and vein are surgically connected, allowing blood to flow from the artery into the vein, which will eventually enlarge and strengthen.
- Maturation Period: Post-surgery, the AV fistula requires several weeks to mature before it can be used for dialysis. During this time, the vein thickens and becomes more suitable for repeated needle insertions.
Considerations and Risks
While AV fistulas are generally safe and effective, certain factors can affect their success:
- Maturation Failure: Some patients may experience complications that prevent the fistula from maturing properly, often due to underlying health conditions like diabetes or hypertension.
- Steal Syndrome: This condition occurs when blood flow is diverted away from the hand or fingers, leading to pain or numbness.
At Sheikh Shakhbout Medical City, the creation of arteriovenous fistulas is performed by skilled vascular specialists dedicated to providing high-quality care for patients requiring dialysis.
