Management of Peripheral Artery Disease with Lower Leg Wounds

Immediate Clinical Assessment Required

The American College of Cardiology recommends urgent vascular assessment to determine if a patient has chronic limb-threatening ischemia (CLTI) requiring revascularization, while simultaneously optimizing medical therapy with consideration for adding rivaroxaban 2.5 mg twice daily to aspirin regimen, and ensuring high-intensity statin therapy with an LDL-C goal of <55 mg/dL 1, 2, 3
The presence of non-healing wounds is a defining feature of CLTI, which manifests as ischemic rest pain, non-healing wounds/ulcers, or gangrene with symptoms present for >2 weeks, and carries a historically estimated 1-year mortality rate of 25-35% and 1-year amputation rate up to 30% 2
The American College of Cardiology suggests that CLTI is strongly suggested by a patient's presentation of lower leg wounds with intermittent leg pain and cramping, rather than simple claudication 2

The American College of Cardiology recommends performing ankle-brachial index (ABI) measurement immediately to quantify the severity of arterial insufficiency 2, 4
A comprehensive vascular examination and inspection of legs and feet is recommended to assess wound characteristics, presence of pulses, and signs of critical ischemia 2
Assessment for signs of infection in the wounds is crucial, as the WIfI (wound, ischemia, and foot infection) classification helps estimate amputation risk 2

The American College of Cardiology recommends ensuring patients with PAD are on high-intensity statin therapy with an LDL-C reduction by ≥50% from baseline and an LDL-C goal of <55 mg/dL 1
The American Heart Association recommends antiplatelet therapy, such as aspirin 75-325 mg daily or clopidogrel 75 mg daily, to reduce MI, stroke, and vascular death in patients with symptomatic PAD (Class I, Level A) 5, 4, 6
The European Society of Cardiology recommends full oral anticoagulation in patients with PAD and newly diagnosed AF with CHA2DS2-VASc score ≥2 1

The American College of Cardiology suggests coordinating immediate wound care with a multispecialty team including podiatry or wound care specialists 3
Assessment for infection requiring antibiotics, implementation of appropriate wound dressings, and offloading strategies are recommended 8
Ensuring adequate glycemic control is beneficial for patients with CLTI to reduce limb-related outcomes (Class IIa, Level B-NR) 5

The American College of Cardiology recommends urgent vascular surgery or interventional radiology consultation if CLTI is confirmed, to determine if the patient is a candidate for revascularization (endovascular or surgical) 2, 3

Delaying vascular assessment in the presence of wounds may represent CLTI requiring urgent intervention to prevent amputation 2
Wounds may not heal with medical therapy alone if significant arterial insufficiency is present 2, 3
Triple therapy (full-dose anticoagulation plus dual antiplatelet therapy) should be avoided unless absolutely necessary due to prohibitive bleeding risk 5, 4
