[Incapacitating angina pectoris treated with electric stimulation of the spinal cord].
Thirty patients who had severe incapacitating angina pectoris which had not reacted to the conventional therapeutic measures and which required massive daily opioid consumption were treated with electrical spinal cord stimulation (SCS) by means of a completely implantable stimulation system. The therapeutic effect was good in 87% of the patients who experienced considerably reduced frequency of attacks and markedly reduced opioid consumption (p less than 0.00005). Nine of the patients could reduce opioid consumption and 14 out of 27 could cease their otherwise daily opioid consumption. In four patients, the therapeutic effect was unsatisfactory. In the first 22 patients in whom a unipolar electrode was introduced, displacement of the electrode and subsequent reoperation was a frequent problem. This problem disappeared after change to multipolar electrodes as slight changes in placing of the electrode could easily be compensated for via the external programming equipment. This investigation reveals that SCS is a good therapeutic alternative for this selected patient category.
