Official Description

Bypass graft, with vein; axillary-femoral-femoral

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An axillary-femoral-femoral bypass graft is a surgical procedure designed to reroute blood flow around a diseased or obstructed segment of the aorta and/or iliac arteries. This procedure is particularly important in cases where blood flow is compromised due to vascular disease, which can lead to significant complications if not addressed. The term "bypass graft" refers to the use of a vein graft to create a new pathway for blood to travel, effectively bypassing the obstructed area. The procedure involves making incisions in both the chest and groin to access the axillary and femoral arteries, respectively. The surgical team meticulously dissects soft tissue to expose these arteries, allowing for the creation of tunnels through which the vein graft will be placed. The harvesting of the vein graft, often from the saphenous vein in the leg, is a critical step, as it provides the necessary conduit for the bypass. The successful completion of this procedure is assessed by checking blood flow through the graft and evaluating distal pulses to ensure that the bypass is functioning properly and that blood is being delivered effectively to the lower extremities.

1. Indications

The axillary-femoral-femoral bypass graft procedure is indicated for patients experiencing significant vascular obstruction or disease that impairs blood flow to the lower extremities. The following conditions may warrant this surgical intervention:

  • Obstructive Aortic Disease - This includes conditions where the aorta is narrowed or blocked, leading to reduced blood flow.
  • Iliac Artery Disease - Obstruction in the iliac arteries can cause claudication and other symptoms due to inadequate blood supply.
  • Peripheral Artery Disease (PAD) - Patients with PAD may require bypass grafting to restore adequate blood flow to the legs.

2. Procedure

The axillary-femoral-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. Soft tissue is carefully dissected to expose the artery. Additionally, two incisions are made in the groin over the common femoral arteries, where soft tissue is also dissected to reveal both common femoral arteries.
  • Step 2: Tunnel Creation - A tunnel is created starting from the exposed axillary artery, passing down through the chest and abdomen, under the inguinal ligament, and terminating at the ipsilateral common femoral artery. A second tunnel is created from the lower abdomen to the contralateral common femoral artery, facilitating the placement of the vein graft.
  • Step 3: Vein Graft Harvesting - A vein graft is harvested, typically from the saphenous vein. 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 to be used is ligated proximally and distally, divided, and removed from the leg.
  • Step 4: Graft Attachment - Vascular clamps are applied to the axillary artery, and an incision is made in the artery. The harvested vein graft is sutured to the axillary artery and then passed through the previously created tunnel to the ipsilateral common femoral artery, which is also clamped and incised. The vein graft is then sutured to the ipsilateral common femoral artery.
  • Step 5: Contralateral Graft Attachment - The contralateral femoral artery is clamped and incised, and the vein graft is sutured to this artery as well. This establishes the bypass route for blood flow.
  • Step 6: Final Checks - After all sutures are in place, the vascular clamps are removed. Blood flow through the graft is checked using Doppler ultrasound to ensure proper function. Distal pulses are evaluated to confirm the patency of the bypass graft.

3. Post-Procedure

Post-procedure care for patients undergoing an axillary-femoral-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 healthcare providers will assess distal pulses regularly. Pain management and wound care are also essential components of post-operative care. Patients may be advised on activity restrictions and rehabilitation to promote recovery and ensure the success of the graft.
