Intermittent claudication can be due to spinal canal stenosis. In order to define the frequency with which this condition presents to a vascular surgeon a review of 271 patients referred with claudication was carried out. Twenty-one (8%) were ultimately diagnosed as having spinal stenosis. There were no significant differences with regard to age or sex between these patients and those with true vascular claudication. There was, however, a significantly lower number of smokers in the spinal stenosis group. When the presenting features of the spinal stenosis group were analysed 62% (13/21) reported sensory symptoms such as numbness or parasthesiae, 38% (8/21) back pain and 67% (14/21) true pain in the legs on walking. In 71% (15/21), symptoms were reported as being bilateral and 29% (6/21) had reduced Doppler pressures. It is stressed that vascular surgeons need to maintain a high index of suspicion for spinal stenosis especially as the condition may coexist with vascular disease, making diagnosis difficult.
间歇性跛行可能由椎管狭窄引起。为了确定这种情况在血管外科医生处就诊的频率，对271例因跛行前来就诊的患者进行了回顾性研究。其中21例（8%）最终被诊断为患有椎管狭窄。这些患者与真正血管性跛行患者在年龄或性别方面无显著差异。然而，椎管狭窄组中的吸烟者数量明显较少。对椎管狭窄组的临床表现进行分析时，62%（13/21）报告有感觉症状，如麻木或感觉异常，38%（8/21）有背痛，67%（14/21）在行走时有腿部真性疼痛。71%（15/21）的患者症状为双侧性，29%（6/21）的患者多普勒压力降低。需要强调的是，血管外科医生对椎管狭窄需要保持高度怀疑，尤其是因为这种情况可能与血管疾病并存，从而使诊断变得困难。
