Abstract

Patients with limb loss face the challenge of having an increased risk of skin disease at residual limb sites. Hyperhidrosis is a common concern for persons with amputation and excessive sweat can cause various skin pathology. Recently, microwave thermoablation (MT) was reported as an effective off-label treatment for hyperhidrosis in patients with limb loss. We present a case in which a patient following MT procedure for hyperhidrosis of a transtibial amputation developed multifocal full thickness cutaneous necrosis and deep venous thrombosis. The possible aetiologies of these complications are discussed including vascular congestion and external thermal injury. Such a case warrants the attention of individuals and providers seeking to use MT for off-label purposes, particularly for patients with limb loss, due to the large treatment surface area and potential for temporary or permanent functional loss of the amputated limb.
