ABSTRACT
Palmoplantar hyperhidrosis is a functional disease with an unknown pathogenesis, making it challenging to find a lasting and effective treatment. This article reports a case of a 43-year-old patient with palmoplantar hyperhidrosis treated with computed tomography (CT)-guided radiofrequency neurotomy (RFN) of bilateral T3-4 sympathetic chain combined with bilateral L3 sympathetic ganglion. The optimal puncture level and skin entry point were selected, and measurements were taken using a CT tool to determine needle depth, angle, and distance from the midline. A sympathetic needle was inserted through the T4 intercostal space to the outer side of the T4 rib head. The needle position was adjusted to achieve a tissue resistance, confirmed through sensory, motor stimulation, and three-dimensional reconstruction. RFN was performed, and this process was repeated for 1-2 cycles. Subsequently, a similar procedure was performed at the L3 sympathetic ganglion under CT guidance, resulting in improved sweating symptoms in the patient’s hands and feet.
