Peroneal-plantar artery bypass: a prone approach

Area of Science:

• Vascular Surgery
• Reconstructive Microsurgery
• Diabetic Foot Complications

Background:

• Distal bypass to the plantar artery is crucial for treating critical limb ischemia.
• Limited venous conduit and previous surgical sites pose challenges for traditional bypass procedures.
• The peroneal artery is a potential source for distal revascularization.

Observation:

• A previously undescribed surgical space posterior to the distal tibia and anterior to the Achilles' tendon was identified.
• This space allows bypass grafts to access the plantar artery.
• Grafts can utilize the communicating branch of the peroneal artery to reach the medial foot.

Findings:

• A prone surgical approach for distal peroneal artery bypass was developed.
• This approach facilitates surgical exposure and preserves valuable venous grafts.
• The technique successfully revascularized a diabetic patient with recurrent foot ischemia and infection after failed femorotibial bypass.

Implications:

• This peroneal-plantar bypass offers a novel strategy for limb salvage in complex cases of critical limb ischemia.
• The prone approach may improve outcomes by optimizing graft utilization and avoiding compromised tissues.
• Further studies are warranted to evaluate the long-term efficacy and applicability of this technique.
