髓核压迫硬膜囊存在占位和支撑2种机制，作用机制不同可能是导致临床表现不同的原因之一。

Any adhesions between the posterior longitudinal ligament and the anterior surface of the thecal sac are released by dissection.

分离后纵韧带与硬膜囊之间的所有粘着物。

These steps decompress the posterioraspect of the thecal sac.

这些步骤起到了减压的作用。

To compare direct measures of postoperative hematoma volume against a new measure of hematoma effect on the thecal sac: the critical ratio.

目标：比较术后直接测量血肿体积与一个新的血肿对囊壁作用标度的差别。

Once this is done, the thecal sac can be easily retracted to provide better exposure of the posterior portion of the vertebral body and the intervertebral discs.

Results. After decompression, 58% of patients developed epidural hematoma of sufficient magnitude to compress the thecal sac beyond its preoperative state at one or more levels.

结果：减压后，58%的患者发生了硬膜外血肿，血肿体积大，较术前在一个或多个节段压迫硬膜范围更大。

The critical ratio correlates more closely with the presence or absence of postoperative symptoms than measures of hematoma volume, and is consistent with the clinical expectation that greater thecal sac compression may result in more severe symptoms.

并且与临床上越严重的囊壁压迫会导致越严重的症状的猜测相一致。

Relative thecal sac compression due to hematoma was calculated at all levels where postoperative cross-sectional area was smaller than preoperative.

Digital imaging software was used to calculate thecal sac cross sectional area on pre- and postoperative MRI at each level, hematoma volume, volume per level decompressed, and critical ratio for each patient.

使用数码影像软件计算了每个病例术前和术后MRI每一个节段的囊壁横截面积、血肿体积、每个减压节段的体积和标准比。

Thecal sac cross-sectional area was calculated at each disc space.

计算每个椎间隙处的硬膜囊横断面积。
