Bypass graft, with vein; popliteal-tibial, -peroneal artery or other distal vessels
CPT4 code
Name of the Procedure:
Bypass Graft with Vein to Popliteal-Tibial or Peroneal Artery (Peripheral Artery Bypass)
Summary
In this surgical procedure, a vein from another part of the patient's body is used to create a new pathway for blood flow around a blocked or narrowed section of the popliteal, tibial, or peroneal arteries in the leg. This helps restore adequate blood flow to the lower leg and foot.
Purpose
Medical Condition or Problem:
- Peripheral artery disease (PAD)
- Critical limb ischemia ##### Goals or Expected Outcomes:
- Restore blood flow to the lower leg and foot
- Alleviate pain and discomfort
- Prevent tissue damage and potential amputation
- Improve mobility and quality of life
Indications
Specific Symptoms or Conditions:
- Severe leg pain, particularly at rest
- Non-healing leg or foot wounds
- Gangrene or tissue loss ##### Patient Criteria:
- Diagnosed with significant artery blockage in the lower leg
- Non-responsive to non-surgical treatments like medication or angioplasty
- Suitable overall health for surgery
Preparation
- Fasting for at least 8 hours prior to surgery
- Stopping certain medications as instructed, particularly blood thinners
- Preoperative tests such as blood work, EKG, and imaging studies (e.g., ultrasound, angiography)
- Briefing on what to expect, signing consent forms
Procedure Description
- Anesthesia: General or regional anesthesia is administered.
- Incision: An incision is made to access the blocked artery and another to harvest the vein (usually from the leg).
- Vein Harvesting: The surgeon removes the vein and prepares it for grafting.
- Bypass Creation: The harvested vein is stitched above and below the blocked artery to create a new route for blood flow.
- Closure: Incisions are closed with sutures or staples, and the areas are bandaged.
Tools and Equipment:
- Surgical instruments for incision and suturing
- Medical imaging devices to guide the procedure
- Anesthesia equipment
Duration
The procedure typically takes between 3 to 5 hours.
Setting
Performed in a hospital operating room.
Personnel
- Vascular surgeon
- Anesthesiologist
- Surgical nurse
- Operating room technicians
Risks and Complications
Common Risks:
- Infection
- Bleeding
- Blood clots ##### Rare Risks:
- Graft failure or blockage
- Nerve damage
- Heart attack or stroke
Benefits
- Improved blood circulation to the leg and foot
- Pain relief and enhanced mobility
- Healing of ulcers or wounds
- Prevention of further tissue damage or amputation ##### Realization Time:
- Benefits are often realized within days to weeks after the procedure.
Recovery
Post-Procedure Care:
- Hospital stay of several days for monitoring
- Pain management with prescribed medications
- Instructions on wound care and activity limitations ##### Recovery Time:
- Full recovery typically takes 6-8 weeks
- Avoid strenuous activities and heavy lifting
- Follow up appointments to monitor progress
Alternatives
Other Treatment Options:
- Medications (e.g., antiplatelet agents, statins)
- Minimally invasive procedures like angioplasty and stenting
- Lifestyle modifications (e.g., smoking cessation, exercise) ##### Pros and Cons:
- Medications and minimally invasive procedures may be less risky but also less effective for advanced PAD.
Patient Experience
During Procedure:
- Under anesthesia, so no pain or awareness. ##### After Procedure:
- Soreness and some pain in the incision areas
- Pain management with medication
- Gradual return to normal activities with guidance from healthcare providers
- Regular follow-up to ensure successful recovery
Pain Management and Comfort Measures:
- Pain relief medications
- Encouragement to engage in light activities as tolerated to promote circulation and healing.
