[Electric stimulation of the spinal cord in arterial diseases of the legs. A multicenter study of 244 patients].
From January 1985 through January 1990, 244 patients (168 males, 76 females, mean age: 69 +/- 14 years) received epidural spinal cord stimulation for the treatment of advanced, nonreconstructable, peripheral vascular disease of the lower limbs due to atherosclerosis in 180 patients, atherosclerosis and/or diabetes in 49, and thromboangiitis obliterans in 15 patients: previous surgery included 101 bypass-grafts in 70 patients, 51% of which below the knee, and 117 sympathectomies in 113 patients as the last resource in face of distal peripheral vascular disease of the lower limbs. Mean ankle-to brachial systolic pressure ratio was .31 +/- .34 on symptomatic limbs; due to pain and advanced disease, walking capacity was assessed in only 151 patients, either on treadmill in 25, or in a metered corridor in 126; angiogram of the lower limbs was performed in every patient unless one not older than three months was readily available; pain at rest was assessed after an analogical scale; partial transcutaneous oxygen tension was measured on the dorsum of the fore-foot of 77 symptomatic limbs (mean: 13.35 +/- 14 mmHg). According to clinical and functional evaluation, 18 patients had exertional ischemia (group I), 87 had permanent ischemia with pain at rest and no tissue loss (group II), and 139 had chronic tissue loss (group III), including 93 ischemic ulcers (mean surface: 3.7 cm2, mean duration: 3.5 months) in 88 patients, 27 limited gangrene, and 24 previous limited non-healing distal amputation. After temporary spinal cord stimulation at T12-L1 level (mean duration: 9 +/- 4 days) with a percutaneous quadripolar electrode lead had allowed for selection of responders, 212 patients received an implantable neurostimulator.(ABSTRACT TRUNCATED AT 250 WORDS)
