Bypass graft, with vein; carotid-contralateral carotid
CPT4 code
Name of the Procedure:
Bypass Graft, with Vein; Carotid-Contralateral Carotid (Common names: Carotid Bypass Surgery, Carotid-Contralateral Bypass)
Summary
This surgery involves creating a new route for blood flow to bypass a blocked or narrow segment of the carotid artery by using a vein graft from another part of the body. It connects the carotid artery on one side of the neck to the carotid artery on the other side.
Purpose
The procedure is designed to improve blood flow to the brain and reduce the risk of stroke for patients with significant carotid artery blockages.
Indications
- Severe carotid artery stenosis (narrowing)
- Recurrent strokes or transient ischemic attacks (TIAs)
- Patients who cannot undergo standard carotid endarterectomy or stenting
Preparation
- Fasting (typically, no food or drink) for 8 hours before the procedure.
- Medication adjustments as directed by your doctor.
- Pre-operative diagnostic tests such as ultrasound, CT scans, or MRIs to assess blood flow and determine the best vein for grafting.
Procedure Description
- Anesthesia: The patient is put under general anesthesia.
- Incision: A small incision is made in the neck to expose the carotid arteries.
- Graft Harvesting: A suitable vein, often the saphenous vein from the leg, is harvested.
- Grafting: The harvested vein is then attached to the carotid artery above and below the blockage, creating a new path for blood flow.
- Completion: The incisions are closed with sutures, and the patient is monitored as anesthesia wears off.
Duration
The procedure typically takes 3 to 5 hours, depending on the complexity and the patient’s condition.
Setting
Performed in a hospital operating room under sterile conditions.
Personnel
- Vascular surgeon
- Surgical nurses
- Anesthesiologist
- Surgical assistants
Risks and Complications
- Common: Infection, bleeding, blood clots
- Rare: Nerve injury, heart attack, stroke, graft failure
- Management: Antibiotics for infections, anticoagulants for clots, and close monitoring
Benefits
- Significantly improved blood flow to the brain
- Reduced risk of stroke
- Symptom relief from previous stroke or TIAs
Recovery
- Hospital stay of 3-5 days post-surgery
- Pain management with prescribed medication
- Avoid strenuous activities for a few weeks
- Follow-up visits to ensure proper healing and function of the graft
Alternatives
- Carotid endarterectomy: Less invasive but not suitable for all patients.
- Carotid artery stenting: A minimally invasive option with different risk profiles.
- Medical management: Lifestyle changes and medications, though less effective for severe blockages.
Patient Experience
Patients may experience some pain and discomfort at the surgical site, and there is typically some grogginess post-anesthesia. Pain management measures will be provided to ensure comfort during recovery. Full recovery and return to normal activities can be expected within a few weeks.
