Arteriovenous Fistulogram
Arteriovenous Fistulogram: Assessing Functionality of Vascular Access for Haemodialysis
An arteriovenous fistulogram is a diagnostic procedure used to evaluate the patency and functionality of an arteriovenous fistula (AVF), a surgically created connection between an artery and a vein, commonly used as vascular access for haemodialysis. This imaging test involves injecting contrast dye into the AVF and capturing X-ray images to assess blood flow and detect any abnormalities or blockages within the fistula. Dr. Devender Singh, a distinguished vascular surgeon in Hyderabad, utilises arteriovenous fistulography with precision and expertise to optimise vascular access for haemodialysis patients.
Understanding Arteriovenous Fistulogram:
Arteriovenous fistulography is performed to evaluate the condition of the AVF and identify any issues that may affect its function or patency. During the procedure, contrast dye is injected into the AVF using a catheter, and X-ray images are taken to visualise the flow of contrast through the fistula and surrounding blood vessels. The images obtained help assess the diameter, length, and integrity of the AVF, as well as identify any stenosis (narrowing), thrombosis (clotting), or other abnormalities that may compromise blood flow.
Procedure Overview:
Preoperative Preparation:
- Before arteriovenous fistulogram, patients may undergo blood tests and medical history review to ensure they are suitable candidates for the procedure.
- Patients are informed about the risks and benefits of the procedure and any necessary precautions or preparations.
Anaesthesia and Access:
- Arteriovenous fistulography is typically performed under local anaesthesia to numb the skin and minimise discomfort during catheter insertion.
- A small incision is made near the AVF, and a catheter is inserted into the fistula under ultrasound or fluoroscopic guidance.
Contrast Injection and Imaging:
- Once the catheter is positioned within the AVF, contrast dye is injected, and X-ray images are captured in real-time to visualise the flow of contrast through the fistula and surrounding blood vessels.
- Multiple images may be taken from different angles to assess the entire length of the AVF and identify any abnormalities or blockages.
Image Interpretation and Reporting:
- The X-ray images obtained during arteriovenous fistulography are analysed by a radiologist or vascular specialist to evaluate the patency, diameter, and functionality of the AVF.
- A comprehensive report detailing the findings of the procedure is generated and shared with the patient’s healthcare provider for further management and treatment planning.
Postoperative Care and Monitoring:
- After arteriovenous fistulography, patients may experience mild discomfort or bruising at the catheter insertion site, which typically resolves within a few days.
- Patients are monitored for any signs of complications, such as bleeding, infection, or allergic reactions to the contrast dye.
Benefits of Arteriovenous Fistulogram:
- Comprehensive Evaluation: Arteriovenous fistulography provides detailed information about the condition of the AVF, allowing for accurate assessment of its functionality and patency.
- Early Detection of Abnormalities: By identifying stenosis, thrombosis, or other abnormalities within the AVF, arteriovenous fistulography enables timely intervention to prevent complications and maintain vascular access for haemodialysis.
- Personalised Treatment Planning: The findings of arteriovenous fistulography guide treatment decisions, such as angioplasty, stent placement, or surgical revision, to optimise the function and longevity of the AVF.
- Improved Patient Outcomes: By ensuring the patency and functionality of the AVF, arteriovenous fistulography contributes to improved outcomes and quality of life for patients undergoing haemodialysis.
