脑受压

ResultsAmong 8 cases,there were low or low slightly density as in 7 cases, single high slightly density tubercle as in 1 case, following these,there were multiple neoplasm metastasis of brain other sites in 2 cases, annular shape enhancement in 3 cases after contrast CT scanning, peripheral edema lightly as in 6 cases and no in 2 cases, suprasellar region, ambiens cisterna and corpora quadrigemina were compressed, transposited and distorted differentlly,and obturated or widened locally.

结果7例脑干转移瘤呈低或略低密度影，1例单一结节为略高密度影，伴随脑内其他部位多发转移2例，3例增强扫描呈环形强化，较度水肿6例，无水肿2例，环池有不同程度受压移位、变形，以及局限性闭塞或增宽。

Results There was difference in the accurance of intra-operative acute encephalocele and postoperative brain incarceration between two groups.

结果 术中急性脑膨出及术后脑嵌顿发生率在两组间比较有差异；术后中线移位、环池受压情况及术后脑积水、硬膜下积液发生率比较均无明显差异。

Some grow focally as an expansile mass or a large exotic lesion.These have heterogeneousdensity and show prominent enhance...

脑干肿瘤CT 诊断基于第四脑室的受压移位，和脑干周围脑池的狭窄变形。

Mid-line shift(81%), lateral cerebral ventricle allaxis due to be compressed(67%), plica of cerebral convolution gather together and ingression(89%) and grey matter of brain ingression(78%) were seen in the cases.

并中线结构移位占81%，侧脑室受压变形占67%，脑回皱襞聚拢内移占89%，脑灰白质内移占78%。

Results The clinical manifestation of brain stem hemorrhage secondary to cerebral infarction included sudden onset,evelution abruptly,coma,quadriplegia,higher fever and respiratory failure. CT usually do not identify the high dense location of brain stem. Large infarction of cerebral hemisphere may lead to shift the brain laterally and downward to produce herniation with subsequent brain stem compression,shift and distortion. Secondary brain stem hemorrhage occured usually in midderline area of midbrain or pontine.

结果 脑梗塞继发脑干出血的临床特点是发病急、进展快、昏迷、四肢瘫、过高热及呼吸衰竭，CT一般不能发现脑干高密度病灶，病理结果均为半球大病灶脑梗塞，严重海马回疝致脑干严重受压、变形和移位，继发脑干出血以中脑为主，可累及桥脑，主要位于中线部位。

Uncomfortable symptoms including dizziness, dim eyesight, cardiopalmus, acratia will appear when seated for a long time because of cerebral blood flow reduced for the reason of cervical vessels flexure or compressed, which result in lack of oxygen and nutritive materials.

由于久坐头处于前屈位，颈部血管轻度屈曲或受压，会使流向脑部的血流受到限制，脑血流量减少，从而造成大脑的氧和营养物质供应不足，出现头晕、眼花、心悸、乏力、手足麻木等不适症状。

Symptoms are nonspecific with cauda equina syndrome, monoparesis, radicular or low back pain, paresthesias, and gait disturbances. CSF cytology is positive in 75% of cases. Prognosis is poor with 80% of patients dying within 4 months.

马尾受压综合症的临床症状是非特异性的，单侧肢体轻偏瘫、下腰部疼痛、感觉异常、步态不稳。75％的病例脑脊液检查是阳性。80％的病人预后不良、在4个月内死亡。

Microsurgery cerebelli tentorium inciseon and local application of papaverine could take effect on reducing brain

显微手术天幕缘切开、罂粟碱明胶海棉片贴敷能够彻底解除脑干受压、防治血管痉挛进而减轻由此引发的脑干继发性损伤，降低病残率和死亡率。

Also, the CT value was 65Hu or so. Around the shadow was a low-density strip of brain edema and the left ventricle was found to have been slightly pressed. Fortunately, except for that, the remaining ventricles, cerebral cisternae, and cerebral sulcus remained normal.

此时，带患者前去医院就诊， CT 显示：患者左侧基底节区见一约3.0×1.5cm 2大小高密度阴影，其 CT 值约65Hu 左右，其周围见低密度水肿带，左侧脑室轻度受压，其它所见脑室、脑池、脑沟无异常。
