The Effect of Lumbar Spinal Stenosis on Results of Treatment in Peripheral Arterial Disease / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the result of percutaneous transluminal angioplasty (PTA) in patients with concurrent lumbar spinal stenosis (LSS) and peripheral arterial disease (PAD). MATERIALS AND METHODS: Patients who underwent PTA for intermittent claudication were evaluated retrospectively. Twenty-two patients with severe LSS were included in group A and 23 patients with no or mild LSS in group B. The symptomatic improvement after PTA was comparatively evaluated. RESULTS: Visual analogue scale (VAS) and Walking Impairment Questionnaire (WIQ) scores showed significant improvement after PTA in both groups (p<0.001, <0.001). However, according to VAS, WIQ and modified MacNab scores, results of group A were less satisfactory (p<0.001, <0.001, p=0.03). Only 2 patients underwent additional spine surgery. CONCLUSION: In results of PTA, the PAD associated LSS group showed less improvement than the PAD only group, but most patients showed symptomatic improvement with conservative treatment.
