L5~S1脊神经根变异1例
A Case of L5-S1 Spinal Nerve Root Variation

腰骶神经根异常虽然罕见，但迄今为止在医学文献中已有部分被详细记载。早期诊断这些异常可能是困难的，但发展具体的方法来描述它们是至关重要的。术前利用影像学来诊断腰骶神经根异常，有助于全面的手术规划，以避免患者在手术中出现不必要的并发症。但仍有部分变异无法通过影像学来明确，腰骶神经根异常是腰椎手术失败的原因之一，术前和围手术期应谨慎评估，以防止神经损伤。这些异常的手术处理取决于患者是否存在相关的神经系统问题，无症状的病例不需要治疗，而患有腰痛或下肢痛的患者需要手术干预，以减压神经根。我们报告一位68岁的女性，以腰痛伴双下肢麻痛为表现。术中发现异常的L5/S1神经根。
Although lumbosacral nerve root abnormality is rare, it has been partially documented in medical literature so far. Diagnosing these abnormalities early can be difficult, but developing specific methods to describe them is crucial. Preoperative imaging is used to diagnose abnormal lumbosacral nerve roots, which is helpful for comprehensive surgical planning to avoid unnecessary complications during the operation. But there are still some variations that cannot be clarified by imaging. Abnormal lumbosacral nerve root is one of the reasons for the failure of lumbar spine surgery. Preoperative and perioperative assessments should be carefully evaluated to prevent nerve damage. The surgical management of these abnormalities depends on whether the patient has related neurological problems. Asymptomatic cases do not require treatment. Patients suffering from low back pain or lower limb pain require surgical intervention to decompress nerve roots. We report a 68-year-old woman with low back pain and numbness in both legs. Abnormal L5/S1 nerve roots were found during the operation.
