目的 探讨自发性蛛网膜下腔出血 (SAH)患者头颅CT和腰穿在诊断中的价值。方法 对 32例SAH患者行头颅CT和腰穿。结果 腰穿的阳性率为 10 0 % ,CT的阳性率为 71.88%。结论 提示临床医生凡临床上怀疑SAH而CT扫描未见异常者应做腰穿和脑脊液检查 ,对SAH的诊断具有决定意义的是腰穿而不是CT扫描。
Objective To investigate the value of skull CT and lumbar puncture in the diagnosis of patients with spontaneous subarachnoid hemorrhage (SAH). Methods 32 cases of SAH patients underwent CT and lumbar puncture. Results The positive rate of lumbar puncture was 100% and the positive rate of CT was 71.88%. Conclusions Clinicians suggest that lumbar puncture and cerebrospinal fluid tests should be performed on patients who have clinically suspected SAH but no CT scan abnormalities. The diagnosis of SAH is of decisive importance in lumbar puncture rather than CT scan.
