Spinal stenosis and neurogenic claudication.

摘要: Neurogenic claudication is diagnosed from a classical history and complementary spinal imaging. The abnormal signs may be few. It should distinguished intermittent (peripheral vascular disease), referred pain the back or root that aggravated by walking, psychological distress. Pathologically, developmentally small canal usually affected multiple levels of segmental degenerative change, with venous pooling in cauda equina between two low pressure stenosis. There probably then failure arterial vasodilatation congested roots response to exercise, symptoms legs when walking. Once established, tend neither improve nor deteriorate. Conservative management reasonable. Otherwise decompression at most significant stenotic level adequate obtain good surgical result.
