- Abstract
Thirteen patients (12 males, 1 female, mean age 60.5 years) affected by peripheral vascular disease (21 lower limbs: 9 with intermittent claudication and 12 with rest pain and/or necrosis smaller than 3 cm²) have been studied by means of transcutaneous oxygen tension (TcpO2) measurements. They had been submitted to spinal cord stimulation (SCS) de-vice implant from one day to twenty-two months previously. In 8 patients (15 limbs) implanted from one day to twenty-two months, the TcpO2 index was calculated to evaluate the neuro-stimulator effect on peripheral blood circulation. In 5 patients (6 limbs) studied before definitive implantation, preoperative and postoperative TcpO2 measurements were able to predict the SCS efficacy during the temporary trial period: when TcpO2 did not increase immediately (4 limbs), no result was achieved (amputation); a TcpO2 increase corresponded to relief of symptoms (2 limbs). On the basis of this preliminary report, TcpO2 measurement could be useful for predicting SCS efficacy in vascular patients; the possibility of dividing the patients into responders and nonresponders to SCS by TcpO2 measurement represents an important achievement in determining the indication for SCS implant.
