Results of HE dye after cerebral alchemic reperfusion showed: Cortex was infiltrated by neutrophil; Cells of corpus striatum and cortex of parietal lobe were stained light; the number off cells obviously reduced; the feature of cells necrosis, such as cells swelling, nuclear fragmentation and lysis et al, would be observed.

HE染色结果显示：脑缺血再灌注后，皮质区中性白细胞浸润，纹状体外侧和顶叶皮质细胞染色淡，细胞数明显 NF－。B在脑缺血再灌注后脑组织局部炎症反应中的作用减少，出现细胞肿胀，胞核碎裂和溶解等细胞坏死特征。

Results Abnormal rate of brain CT was 59.3%, including expansion of ventricles of brain, atrophy of cortex, cerebromalacia; abnormal rate of EEG was 72.2%, including low voltage, allorhythmia of slow wave, deletion of sleep-spindle wave and attack wave.

F total amount 80-122.5 mil, average 102.3±0.71, continuous 7～10 days, to happen Symptom vasospasm 8 case, anesis post-treatment in 5 days,recovery 52 case,midst incomplete 14 case, weight incomplete 10 case, plants exist 11 case, death 3 case, cerbral infarction 2 case , no happing dropsy of brain.

结果 每日分2～3次行腰穿共排放血性脑脊液总量80～122.5ml，平均（102.3±0.71）ml，连续7～10天，发生症状性血管痉挛8例，均在治疗后5天内缓解；痊愈52例，中残14例，重残10例，植物生存11例，死亡3例；出现脑梗死2例，无脑积水发生。

Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.

使用16排螺旋CT对40例患者行头颈部CTA检查，随机分为两组，各20例，所有患者在CTA之前行脑CT平扫及脑CT灌注扫描，A组以CTP所显示的动脉峰值时间作为CTA的延迟时间，扫描方向为自头侧向足侧。B组使用造影剂浓度实时监控跟踪触发技术确定延迟时间，扫描方向自足侧向头侧扫描，两组CTA图像相对照。
