Radiofrequency thermocoagulation of peripheral nerves for acute exacerbation pain of comprehensive chronic limb-threatening ischemia: a case report

Abstract

The patient was a woman in her 50s. She had pain below her ankle joint and was hospitalized due to extensive thrombosis and arterial occlusion below the renal abdominal aorta. She was diagnosed as chronic limb-threatening ischemia (CLTI) of the lower limb. Although amputation was needed, she did not wish to undergo aggressive treatment. Pain was well controlled with radiofrequency thermocoagulation (RF) performed four times. RF of peripheral nerves for CLTI is an effective option for pain relief, considering the patient's prognosis and the balance of activity of daily living.
