37607 Ligation or banding of angioaccess arteriovenous fistula

Name of the Procedure:

Ligation or Banding of Angioaccess Arteriovenous Fistula (AVF).

Summary

Ligation or banding of an arteriovenous fistula involves closing off or partially constricting the abnormal connection between an artery and a vein, commonly created for dialysis access. This is done to address issues like high-output cardiac failure, aneurysms, or malfunctioning fistulas.

Purpose

This procedure is used to manage complications associated with arteriovenous fistulas, such as:

• Reducing excessive blood flow that can lead to high-output heart failure.
• Treating enlarged or aneurysmal fistulas.
• Correcting malfunctioning fistulas that no longer provide effective dialysis access.

The goal is to preserve the patient's overall health by managing these complications while maintaining adequate dialysis access if necessary.

Indications

• Symptoms of high-output cardiac failure (e.g., shortness of breath, fatigue).
• Presence of aneurysm or swelling in the fistula.
• Poor dialysis efficiency or complications arising from the fistula.
• Infection or persistent bleeding at the fistula site.

Preparation

• Patients may need to fast for a certain period before the procedure, commonly 6-8 hours.
• Pre-procedural blood tests and imaging studies, such as ultrasound or angiography, might be required to assess the fistula.
• Adjustment or temporary discontinuation of certain medications, especially blood thinners, as advised by the doctor.

Procedure Description

1. Anesthesia: Local or general anesthesia may be administered depending on the complexity of the procedure.
2. Access: A small incision is made near the fistula site.
3. Ligation or Banding: The surgeon will either tie off (ligate) the fistula completely or place a band to constrict it partially. This may involve suturing around the fistula to reduce its diameter and blood flow.
4. Closure: The incision is closed with sutures and a sterile dressing is applied.

Tools used include surgical sutures, scalpels, and possibly ultrasound guidance.

Duration

The procedure typically takes about 1 to 2 hours, depending on the individual case.

Setting

Performed in a hospital or a specialized surgical center, often in an operating room setting.

Personnel

• Vascular surgeon or general surgeon experienced in vascular access procedures.
• Anesthesiologist or nurse anesthetist.
• Surgical nurses and support staff.

Risks and Complications

• Infection at the incision site.
• Bleeding or hematoma formation.
• Thrombosis (clotting) in the fistula.
• Damage to adjacent blood vessels or nerves.
• Recurrence of fistula-related symptoms if the banding or ligation is insufficient.

Benefits

• Improved symptoms related to high-output cardiac failure.
• Decreased risk of fistula rupture or aneurysm complications.
• Enhanced efficiency and functioning of dialysis if the fistula needs to be preserved.

Recovery

• Hospital stay of 1-2 days for monitoring, especially if general anesthesia is used.
• Keep the incision site clean and dry; follow instructions on wound care.
• Avoid heavy lifting or strenuous activities for a few weeks.
• Follow-up appointments for wound assessment and to evaluate fistula functionality.

Alternatives

• Endovascular techniques: Less invasive options like angioplasty or stent placement.
• Creating a new arteriovenous fistula at an alternative site.
• Use of central venous catheters or other dialysis access methods.

Pros and cons of alternatives depend on individual patient factors like overall health and the severity of the fistula condition.

Patient Experience

• Pre-procedure, patients might feel anxious, but medications can be given to help relax.
• Minimal to moderate pain during the procedure if under local anesthesia; general anesthesia results in no pain during the operation.
• Post-procedure pain managed with prescribed analgesics. Discomfort might include soreness at the incision site.
• Follow proper recovery instructions to minimize discomfort and ensure effective healing.
