Name of the Condition

• Displacement of Surgically Created Arteriovenous Fistula

Summary

• This condition refers to the displacement or shifting of an arteriovenous fistula (AV fistula) that was surgically created, commonly for the purpose of hemodialysis in patients with renal failure. The displacement can affect the fistula’s functionality, potentially compromising its intended purpose.

Causes

• Displacement may occur due to improper surgical technique, trauma to the area, physical activities that strain the fistula, or poor wound healing processes.

Risk Factors

• Factors that increase the risk include recent surgery for fistula creation, underlying connective tissue disorders, and activities or situations that increase pressure or strain on the fistula site.

Symptoms

• Typical symptoms include swelling, pain, and decreased functionality of the fistula, which might manifest as inadequate blood flow for dialysis. Visible moving or shifting of the fistula may also be observed.

Diagnosis

• Diagnosis generally involves physical examination and imaging studies such as ultrasound or angiography to assess the position and functionality of the fistula.

Treatment Options

• Treatment may include repositioning the fistula through surgical intervention, rest and immobilization of the affected area, and in some cases, the use of compression bandages to secure the fistula temporarily.

Prognosis and Follow-Up

• If treated promptly, the prognosis is generally positive with the restoration of proper fistula function. Continuous monitoring and follow-ups are critical to ensure healing and to detect early signs of further complications.

Complications

• Potential complications include infection, thrombosis, or failure of the fistula which can impede the dialysis process and necessitate further surgical intervention.

Lifestyle & Prevention

• Patients are advised to avoid heavy lifting and vigorous activities that may strain the area. Regular check-ups are essential to monitor the health of the fistula.

When to Seek Professional Help

• Seek immediate medical attention if there is persistent pain, visible displacement, swelling, or signs of infection such as redness or discharge at the site.

Tips for Medical Coders

• Ensure accurate documentation of the encounter type, as this code represents an initial encounter for the displacement.

• Avoid confusion with similar issues related to non-surgically created AV fistulas or other post-surgical complications by thoroughly reviewing patient records.
