INTRODUCTION: Neurogenic intermittent claudication (NIC) is a common symptom in patients with lumbar spinal stenosis (LSS). Peripheral arterial disease (PAD) evokes vascular intermittent claudication. Both diseases are prevalent in middle‐aged and elderly people. The purpose of this study was to investigate the clinical characteristics of LSS patients with PAD.

METHODS: This study performed under the Japanese spine research society initiative. A total of 558 patients (299 males, 259 females) diagnosed with LSS by the clinical diagnostic support tool and MRI at 64 medical facilities were enrolled in this study. History taking, physical examination, blood tests, ankle‐brachial index (ABI), the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), and the Short Form 36 (SF‐36) were performed. LSS patients with PAD or ABI below 0.9 were categorized in the LSSPAD group, while LSS patients without PAD were categorized in the control group. Statistical analyses were performed using t tests, Mann‐Whitney's U test, and multivariate recurrence analysis. P values less than 0.05 were considered statistically significant.

RESULTS: The LSSPAD group included 37 patients (6.6%). Of these, 20 (3.6%) had already been diagnosed with PAD, while 17 (3.0%) were diagnosed with PAD based on the ABI measurements in this study.

In the LSSPAD group, the number of elderly patients, the number of males, and the frequency of complication with diabetes, ischemic heart disease and arrhythmia were larger than in the control group (p

DISCUSSION: According to the present results, clinicians should consider the prevalence of PAD in NIC patients, particularly in elderly male patients with diabetes and/or ischemic heart disease and/or arrhythmia.
