Name of the Procedure:

Ultrasound Guided Compression Repair of Arterial Pseudoaneurysm or Arteriovenous Fistulae (includes diagnostic ultrasound evaluation, compression of lesion and imaging)

Summary

Ultrasound guided compression repair is a minimally invasive procedure used to treat abnormal blood vessel connections or outpouchings. It involves using ultrasound imaging to locate the lesion and applying targeted compression to repair it.

Purpose

This procedure is designed to correct issues such as arterial pseudoaneurysms or arteriovenous fistulae. It helps to restore normal blood flow and reduce the risk of complications like bleeding or clot formation.

Indications

• Presence of an arterial pseudoaneurysm or arteriovenous fistulae
• Symptoms such as swelling, pain, or pulsatile mass at the site of the lesion
• Diagnosed via initial ultrasound or other imaging tests

Preparation

• Fasting may be required for a few hours before the procedure
• Adjustments to medications, especially blood thinners, as advised by the physician
• Pre-procedure imaging tests to evaluate the lesion

Procedure Description

1. The patient is positioned comfortably, and the area of interest is cleaned and prepped.
2. An ultrasound probe is used to locate the lesion and to guide the compression therapy.
3. The physician applies targeted external pressure using the ultrasound probe or other compression device to close off the lesion.
4. Continuous ultrasound imaging is used to monitor the effectiveness of the compression.
5. The process may be repeated several times until the lesion is successfully repaired.

Duration

The procedure typically takes between 30 to 60 minutes.

Setting

This procedure is usually performed in a hospital or an outpatient clinic equipped with ultrasound technology.

Personnel

• A trained radiologist or vascular specialist
• Ultrasound technician
• Nursing staff

Risks and Complications

• Minor bruising or discomfort at the compression site
• Temporary soreness
• Rarely, reformation of the pseudoaneurysm or fistulae
• Very rarely, blood clots or infection

Benefits

• Minimally invasive compared to surgical options
• Reduced recovery time
• Immediate correction of blood flow issues

Recovery

• Patients can usually go home the same day
• Post-procedure rest for 24-48 hours
• Avoid heavy lifting or strenuous activities for a few days
• Follow-up ultrasound to confirm successful repair

Alternatives

• Surgical repair of the pseudoaneurysm or arteriovenous fistulae
• Endovascular techniques (e.g., coil embolization)
• Each alternative has different risks and recovery times which should be discussed with the physician

Patient Experience

• Patients might feel some pressure or mild discomfort during the procedure.
• Post-procedure, some soreness or bruising may be experienced at the compression site.
• Pain can usually be managed with over-the-counter pain relievers.
