[Spinal cord electric stimulation vs. femoro-distal bypass in critical ischemia of the legs. Preliminary results in a randomized prospective study].
In the last few years the development of new and improved surgical procedures caused a more aggressive approach, by femoro-distal bypass, to the limb affected by critical ischaemia. A good surgical result is related to the crural vessel patency, the presence of an adequate autologous vein and the possibility to visualize inframalleolar and foot arteries by selective angiograms. Should all these conditions not be present, an outflow procedure might be at high risk for failure. On the other hand, several studies show that SCS relieves rest pain and improves trophic lesion healing although there is no evident increase in peripheral blood flow, but these studies refer to heterogeneous non-randomized patients. In order to evaluate the effectiveness of SCS compared to distal arterial reconstruction, we started this prospective and randomized study. In a period of 15 months, 12 patients affected by critical limb ischaemia at 4th stage of Fontaine with angiographic multilevel distal lesions were randomised for SCS (7 cases: group A) and distal bypass (5 cases: group B). The result of the therapy was judged as good or fair when either complete or evident pain regression and trophic lesion healing were obtained; otherwise the result was considered as poor. Actually the study is in progress, the follow-up is partial (3-12 months), the results are preliminary. In the patients of group A the results were good or fair in 5 cases (72%) and poor in 2 (28%). In the patients of group B the results were good or fair in 2 cases (40%) and poor in 3 (60%).(ABSTRACT TRUNCATED AT 250 WORDS)
