Efficacy, safety and mechanisms of spinal cord stimulation used as an additional therapy for patients suffering from chronic refractory angina pectoris

Spinal cord stimulation: an update

Spinal cord stimulation has been used in the treatment of many chronic pain disorders since 1967. In this update, the indications for spinal cord stimulation are reviewed with attention to recent publications. A focused review of the literature on abdominal and visceral pain syndromes is also provided. Furthermore, the technology has evolved from the use of monopolar electrodes to complex electrode arrays. Similarly, the power source has changed from a radio frequency-driven system to a rechargeable impulse generator. These topics are covered, along with a short discussion of implant technique. Finally, we include a review of complications of such therapy. SCS as a technology and therapy continues to evolve.

A simple approach to outcomes assessment of the therapeutic and cost–benefit success rates for spinal cord stimulation therapy

SCS was found to be cost-effective and therapeutically effective in this study for a majority of patients who had successful trial screening and were determined to be suitable candidates for SCS therapy. This is consistent with prior research if not slightly more encouraging, because typically half of the patients implanted with SCS reported 50% or more pain relief. Strikingly, most patients were considered cost successes. Overall, this study provides continued support that spinal cord stimulation offers the medical community an effective treatment for pain and reduces costs associated with the treatment of chronic intractable pain patients.
