Background: The effect of Ommaya reservoirs on the clinical outcomes of patients with intraventricular hemorrhage (IVH) remains unclear.
Objective: We aimed to determine the effect of combining the Ommaya reservoir and external ventricular drainage (EVD) therapy on IVH and explore better clinical indicators for Ommaya implantation.
Methods: A retrospective analysis was conducted on patients diagnosed with IVH who received EVD-Ommaya drainage between January 2013 and March 2021. The patient population was divided into two groups: the Ommaya-used group, comprising patients in whom the Ommaya drainage system was activated post-surgery, and the Ommaya-unused group, comprising patients in whom the system was not activated. The study analyzed clinical, imaging, and outcome data of the patient population.
Results: A total of 123 patients with IVH were included: 75 patients in the Ommaya-used group and 48 patients in the Ommaya-unused group. The patients in the Ommaya-used group showed a lower 3-month GOS than those in the Ommaya-unused group (p< 0.0001). The modified Graeb scale (mGS) in the Ommaya-unused group was significantly lower than that in the Ommaya-used group before the operation (p< 0.01) but not after surgery (p> 0.05). The GCS in the Ommaya-unused group was significantly lower than that in the other group, and there was a close correlation between the GCS and 3-month GOS (p< 0.0001). The GCS score showed significance in predicting the use of Ommaya (p< 0.001).
Conclusion: The study demonstrated that combining EVD and Ommaya drainage was a safe and feasible treatment for IVH. Additionally, preoperative GCS was found to predict the use of Ommaya drainage in subsequent treatment, providing valuable information for pre-surgery decision-making.

传统 EVD 与 Ommaya 引流相结合治疗脑室内出血 (IVH)

背景： Ommaya 储库对脑室内出血 (IVH) 患者临床结果的影响尚不清楚。
目的：我们旨在确定 Ommaya 储液器与脑室外引流（EVD）联合治疗 IVH 的效果，并探索 Ommaya 植入更好的临床指标。
方法：对 2013 年 1 月至 2021 年 3 月期间接受 EVD-Ommaya 引流的诊断为 IVH 的患者进行回顾性分析。患者群体分为两组：Ommaya 使用组，包括激活 Ommaya 引流系统的患者手术后组和未使用 Ommaya 组，包括未激活该系统的患者。该研究分析了患者群体的临床、影像和结果数据。
结果：共纳入 123 例 IVH 患者：Ommaya 使用组 75 例，未使用 Ommaya 组 48 例。使用 Ommaya 组的患者的 3 个月 GOS 低于未使用 Ommaya 组的患者 (p< 0.0001)。未使用 Ommaya 组的改良 Graeb 量表 (mGS) 显着低于术前使用 Ommaya 的组 (p< 0.01)，但术后没有显着低于使用 Ommaya 的组 (p> 0.05)。未使用 Ommaya 组的 GCS 显着低于另一组，并且 GCS 与 3 个月 GOS 之间存在密切相关性 (p<0.0001)。GCS 评分在预测 Ommaya 的使用方面具有显着性 (p< 0.001)。
结论：研究表明，EVD 和 Ommaya 引流相结合是 IVH 的安全可行的治疗方法。此外，术前 GCS 还可以预测后续治疗中 Ommaya 引流的使用，为术前决策提供有价值的信息。
