What is the treatment for peroneal artery occlusion?

From the Guidelines

The treatment for peroneal artery occlusion typically involves a combination of medical management and possible interventional procedures depending on symptom severity, with a focus on prompt restoration of distal blood flow to prevent limb ischemia and potential amputation 1.

Medical Management

Initial management includes antiplatelet therapy with aspirin (81-325mg daily) or clopidogrel (75mg daily), along with risk factor modification such as smoking cessation, diabetes control, and cholesterol management with statins.

• Antiplatelet therapy is crucial in preventing further clot formation and reducing the risk of recurrent occlusion 1.
• Risk factor modification is essential in managing peripheral arterial disease and preventing disease progression.

Interventional Procedures

For patients with critical limb ischemia or severe symptoms, revascularization may be necessary through endovascular techniques like angioplasty with or without stenting, or surgical bypass using autologous vein grafts (typically saphenous vein) to restore blood flow to the affected limb.

• Catheter-directed thrombolysis using tissue plasminogen activator (tPA) may be employed in cases of acute occlusion, with the goal of rapidly restoring blood flow to the affected limb 1.
• The choice of revascularization modality depends on the type of occlusion (thrombus or embolus), location, duration of ischemia, co-morbidities, and therapy-related risks and outcomes.

Pain Management and Wound Care

Pain management and wound care are essential components of treatment, particularly if tissue damage has occurred.

• Regular follow-up with vascular specialists is important to monitor treatment effectiveness and prevent progression.
• The peroneal artery is often spared in peripheral arterial disease, making it a potential target vessel for distal bypass procedures when other tibial vessels are occluded, which explains why preserving its function is particularly important in limb salvage scenarios 1.

Treatment Options for Peroneal Artery Occlusion

• The treatment for peroneal artery occlusion typically involves a combination of medical and surgical interventions, depending on the severity and cause of the occlusion 2, 3.
• Medical treatment may include:
  • Anticoagulation therapy with heparin to prevent further clotting 4, 5, 3.
  • Antiplatelet therapy with aspirin or clopidogrel to reduce the risk of clot formation 6, 4, 5.
  • Thrombolytic therapy with streptokinase to dissolve existing clots 3.
• Surgical treatment may include:
  • Embolectomy to remove the occluding embolus 3.
  • Artery repair or reconstruction to restore blood flow to the affected area 3.
  • Amputation of non-viable limbs 3.

Specific Treatment Approaches

• For acute peroneal artery ischemia syndrome, treatment with intravenous thrombolysis, anticoagulation, vasodilation, and improving circulation therapy has been shown to be effective in improving symptoms and reducing the risk of complications 2.
• For patients with peripheral arterial disease, antiplatelet therapy with aspirin or clopidogrel is recommended to reduce the risk of cardiovascular events 6, 4, 5.
• For patients undergoing surgical or catheter-based interventions, anticoagulation therapy with heparin and antiplatelet therapy with aspirin are recommended to reduce the risk of thrombosis and improve outcomes 4, 5.
