Abstrakt: Objectives: to evaluate whether transcutaneous oxygen tension (TcpO(2)) measurements could be used as a specific prognostic parameter in selecting diabetic patients for permanent device implantation.
Methods: sixty consecutive diabetic patients (28 with autonomic neuropathy), classified as Fontaine stage III or IV, underwent spinal cord stimulation (SCS) for ischaemic pain, after failed conservative or surgical treatment. Pedal TcpO(2)on the dorsum of the foot and ankle-pressure Doppler measurements were performed before, and 2 and 4 weeks after implantation.
Results: limb salvage and good pain relief were achieved in 35 patients, while in 12 partial pain relief and limb salvage for at least 6 months were obtained. In 13 patients the method failed and the ischaemic limbs were amputated. Only 3 of the 28 patients with neuropathy had any long-term benefit. Limb salvage was achieved in those patients with a significant increase in TcpO(2)within 2 weeks of stimulation. The stage of the neuropathy was inversely related to the success of SCS therapy. The ankle-brachial pressure index (ABPI) did not change after stimulation.
Conclusions: diabetic patients with significant increase of TcpO(2)and pain relief during a 2-week test period may be successfully treated by long-term SCS unless they have advanced autonomic neuropathy.
