ABSTRACT

Study Design: Review of literature on anatomical and pathophysiological features of cauda equina. Objectives: To look into the anatomical and pathophysiological features of cauda equina and support their basic knowledge of treating cauda equina syndrome. Summary of Literature Review: Cauda equina has different anatomical and pathophysiological features to peripheral nerve. Materials and Methods: Review of literature. Results: When compressing to cauda equina, the pathophysiologic mechanism develop as follows; increasing the vascular permiablity of nerve root, intraneural edema, and subsequent blood and nutritional impairment. Nerve root injury develops through this pathophysiologic mechanism. Conclusions: Cauda equina has an extensive ateriovenous anastomosis and guaze-like pia mater, which supply blood and neutrition to it. These anatomical features prevent it from complete cauda equina syndrome when compressing to it under arterial blood pressure.
