Name of the Procedure:

Revision, lower extremity arterial bypass, without thrombectomy, open; with vein patch angioplasty

Summary

This procedure involves the surgical revision of an existing arterial bypass in the lower extremity. It uses a vein patch angioplasty to improve blood flow without removing any blood clots. Essentially, the surgeon reworks the bypass to ensure it functions properly.

Purpose

This surgery is performed to correct or improve a previous bypass in the lower extremity, addressing issues such as graft narrowing or blockage. The goal is to restore adequate blood flow to the leg, alleviating symptoms and preventing further complications like tissue damage or amputation.

Indications

• Symptoms of poor blood circulation in the lower extremity (e.g., pain, claudication, or ulcers)
• Narrowing or failure of a previous arterial bypass
• Peripheral artery disease (PAD) affecting leg arteries
• Adequate general health to tolerate surgery

Preparation

• Fasting for a certain period before the surgery, typically starting at midnight the night before
• Adjustment or temporary discontinuation of certain medications, as advised by the healthcare provider
• Pre-surgical diagnostic tests such as blood tests, imaging studies (e.g., ultrasound, CT angiography), and physical examinations

Procedure Description

1. The patient is given general anesthesia to ensure they are asleep and pain-free.
2. An incision is made at the site of the previous bypass.
3. The surgeon identifies the problematic segment of the bypass graft.
4. A vein patch is harvested (typically from the patient's leg) and is used to widen the narrowed section of the bypass graft.
5. The vein patch is sewn into place, creating a wider passage for blood flow.
6. The incision is closed, and a sterile dressing is applied.

Tools and Equipment:

• Surgical instruments for incision and sewing
• Vein harvesting tools
• Sterile dressings and sutures

Duration

The procedure typically takes 2-4 hours, depending on the complexity of the revision.

Setting

The procedure is performed in a hospital setting, often in a surgical suite equipped for vascular surgeries.

Personnel

• Vascular surgeon
• Surgical nurses
• Anesthesiologist
• Surgical technologists

Risks and Complications

Common Risks:

• Infection at the surgical site
• Bleeding
• Blood clots

Rare Risks:

• Damage to surrounding tissues or organs
• Failure of the graft revision
• Anesthesia-related complications

Benefits

• Improved blood flow to the lower extremity
• Relief from pain and other symptoms associated with poor circulation
• Lower risk of severe complications like tissue damage or amputation
• Ability to resume normal activities with reduced discomfort

Recovery

• Hospital stay for a few days post-surgery for monitoring and recovery
• Follow-up appointments for wound care and assessment of graft function
• Gradual resumption of normal activities as advised by the healthcare provider
• Possible physical therapy to strengthen the leg
• Medications to manage pain and prevent blood clots

Alternatives

• Endovascular procedures such as angioplasty and stenting
• Medications to manage symptoms of PAD
• Lifestyle changes including diet, exercise, and smoking cessation
• Amputation in severe cases where other treatments are not viable

Patient Experience

During the Procedure:

• The patient will be under general anesthesia and will not feel or remember the procedure.

After the Procedure:

• Some pain and discomfort at the incision site, managed with medications
• Likely to have swelling and bruising in the area
• Gradual improvement in symptoms as healing progresses
• Instructions on how to care for the incision and manage activity levels
