Four cases of postoperative spinal canal stenosis were presented in which compression of cauda equina was observed. The lesion was found in 5.8% of operated spinal stenosis (four out of 69 cases). One must pay attention to differentiate the lesion from the recurrence of initial disorder, because the symptoms of the postoperative spinal stenosis is no always typical but sometimes resemble to the symptoms of the initial disorder which needed the operation. Myelography is the only reliable method to decide the extent of the spinal canal stenosis.
本文报告4例术后椎管狭窄病例，均观察到马尾神经受压情况。该病变在接受手术的椎管狭窄病例中占5.8%（69例中有4例）。必须注意将该病变与初始疾病的复发相鉴别，因为术后椎管狭窄的症状并不总是典型的，有时类似于需要手术治疗的初始疾病的症状。脊髓造影是确定椎管狭窄程度的唯一可靠方法。
