Peroneal neuropathy is a common mononeuropathy of the lower limb. Some studies have reported cases of peroneal neuropathy after vascular surgery or intervention. However, no cases of peroneal neuropathy with occlusion of a single peripheral artery have been previously reported. A 73-year-old man was referred with a 3-week history of left-sided foot drop. He had a history of valvular heart disease and arrhythmia, and had previously been treated with percutaneous coronary intervention. Computed tomography angiogram of the lower extremity showed proximal occlusion of the left anterior tibial artery. An electrodiagnostic study confirmed left common peroneal neuropathy. After diagnosis, anticoagulation therapy was started and he received physical therapy.
