Official Description

Bypass graft, with vein; axillary-femoral

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An axillary-femoral bypass graft is a surgical procedure designed to redirect blood flow around a section of the aorta and/or iliac artery that has become diseased or obstructed. This procedure is particularly important for patients who may be experiencing reduced blood flow due to vascular issues, which can lead to serious complications if not addressed. The surgery involves creating a bypass using a vein graft, typically harvested from the patient's leg, to establish a new pathway for blood circulation. The procedure begins with a skin incision made just below the clavicle to access the proximal axillary artery, followed by a second incision in the groin area to expose the common femoral artery. A tunnel is then created to connect these two sites, allowing the vein graft to be placed securely. The meticulous dissection and careful handling of the blood vessels are crucial to ensure the success of the graft and to maintain adequate blood flow to the lower extremities. This procedure is often indicated for patients with significant arterial blockages that could lead to ischemia or other serious vascular conditions.

1. Indications

Indications for performing an axillary-femoral bypass graft include the following conditions:

  • Obstructed Aorta The procedure is indicated when there is a blockage in the aorta that impedes normal blood flow.
  • Obstructed Iliac Artery This surgery may be necessary when the iliac artery is obstructed, affecting blood supply to the lower extremities.
  • Peripheral Arterial Disease (PAD) Patients with PAD may require this bypass to improve blood circulation to the legs and feet.
  • Ischemic Symptoms Symptoms such as claudication or rest pain due to inadequate blood flow may warrant this surgical intervention.

2. Procedure

The axillary-femoral bypass graft procedure involves several critical steps to ensure successful rerouting of blood flow:

  • Step 1: Incision and Exposure A skin incision is made in the chest, just below the clavicle, to access the proximal axillary artery. The surrounding soft tissue is carefully dissected to expose the artery fully. A second incision is then made in the groin area over the common femoral artery, which is also exposed for the procedure.
  • Step 2: Creating the Tunnel A tunnel is created that begins at the exposed section of the axillary artery and extends down through the chest and abdomen, passing under the inguinal ligament, and terminating at the exposed common femoral artery. This tunnel will serve as the pathway for the vein graft.
  • Step 3: Harvesting the Vein Graft If a saphenous vein graft is selected for use, an incision is made in the leg over the section of the saphenous vein to be harvested. The soft tissue surrounding the vein is dissected, and its branches are ligated and divided. The section of vein intended for use is then ligated proximally and distally, divided, and removed from the leg.
  • Step 4: Attaching the Graft Vascular clamps are applied to the axillary artery, and an incision is made in the artery. The harvested vein graft is then sutured to the axillary artery. The graft is passed through the previously created tunnel to reach the common femoral artery.
  • Step 5: Final Connection The common femoral artery is clamped and incised, and the other end of the vein graft is sutured to this artery. Once the connections are secure, the vascular clamps are removed.
  • Step 6: Checking Blood Flow After the clamps are removed, blood flow through the graft is assessed using Doppler ultrasound. Additionally, distal pulses are evaluated to ensure the patency of the bypass graft and confirm that blood is flowing adequately to the lower extremities.

3. Post-Procedure

Post-procedure care for patients who have undergone an axillary-femoral bypass graft includes monitoring for any signs of complications, such as infection or graft failure. Patients are typically observed for adequate blood flow to the lower extremities, and follow-up Doppler studies may be performed to assess graft patency. Pain management and wound care are also essential components of recovery. Patients may be advised on activity restrictions and rehabilitation to promote healing and improve circulation. Regular follow-up appointments are necessary to monitor the patient's progress and ensure the long-term success of the bypass graft.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
