The methodology of measuring chronic subdural hematoma (cSDH) extent and its effect on intracranial structures is relevant for patient classification and outcome measurements and affects the external validity of cSDH studies. With embolization of the middle meningeal artery (MMA) as a possible treatment of cSDHs, the topic has gained substantial interest. We sought to summarize the heterogeneity of radiologic measurements, specifically in the evaluation of cSDHs based on literature review.
In this review, we identified and described the most common radiological methodologies for measurements of cSDH thickness, cSDH volume and of midline shift.
There are numerous published methods on how to evaluate cSDH thickness, cSDH volume and midline shift but no common standard. The definition of measurement methods and reporting standards for MMA embolization in cSDH patients and their validation needs to be addressed.
测量慢性硬脑膜下血肿(cSDH)程度及其对颅内结构影响的方法与患者分类和预后测量相关,并且影响 cSDH 研究的外部有效性。随着脑膜中动脉(MMA)栓塞作为 cSDH 的一种可能治疗方法,该主题引起了广泛关注。我们试图通过文献回顾总结放射学测量的异质性,特别是在 cSDH 的评估方面。
在本综述中,我们确定并描述了最常见的用于测量 cSDH 厚度、cSDH 体积和中线移位的放射学方法。
有许多关于如何评估 cSDH 厚度、cSDH 体积和中线移位的已发表方法,但没有通用标准。需要解决 cSDH 患者 MMA 栓塞的测量方法和报告标准的定义以及验证问题。
