摘要

材料和方法对特发性正常压力脑积水(iNPH)患者进行回顾性研究。进行卡兹曼输液试验,Rout>12 mmHg/ml/min为阳性结果。术前磁共振成像测量了第三脑室的横径和容积。用 NPH 评分评估术后改善情况。结果分析了 52 名患者,平均年龄 76 岁。输液试验结果为阳性和阴性的患者的第三脑室直径没有差异(12.28 毫米对 11.68 毫米;P = 0.14)。两组患者的心室容积也未发现差异(3.6 立方厘米对 3.5 立方厘米;P = 0.66)。与手术后无反应的患者相比,VPS 术后病情好转的患者第三脑室较小(11.85 毫米对 12.96 毫米;P = 0.009)。第三脑室的直径和容积呈显著的强相关性(皮尔逊相关系数 = 0.72;p < 0.0001)。结论:第三脑室的形态变量可能有助于预测特发性正常压力脑积水患者对 VPS 的良好反应。

Utilidad de la volumetría del tercer ventrículo en pacientes con hidrocefalia a presión normal

Objective

To use third ventricle morphometric variables as a tool for the selection of patients with idiopathic normal pressure hydrocephalus (iNPH) who are candidates for ventriculoperitoneal shunts (VPS).

Material and methods

Retrospective study enrolling patients with iNPH. Katzman infusion test was performed and a Rout >12 mmHg/ml/min was considered a positive result. The transverse diameter and the volume of the third ventricle were measured in the preoperative MRI. Postoperative improvement was assessed with the NPH score. The results were analysed with SPSS software.

Results

Fifty-two patients with a mean age of 76 years were analysed. There was no difference in the diameter of the third ventricle among patients with a positive result and those with a negative result in the infusion test (12.28 mm vs. 11.68 mm; p = 0.14). Neither were difference detected in the ventricle volume of both groups (3.6 cm3 vs. 3.5 cm3; p = 0.66). Those patients who improved after VPS had a smaller third ventricle compared to those who did not respond after surgery (11.85 mm vs. 12.96 mm; p = 0.009). Diameter and volume of third ventricle present a significant strong correlation (Pearson correlation coefficient = 0.72; p < 0.0001).

Conclusion

Morphometric variables of third ventricle may be useful in predicting a good response to VPS in patients with idiopathic normal pressure hydrocephalus.
