梗塞

The lesion volume of cerebral ischemia showed significant diffenence between two groups at 24 hour and 7 days after MCAO/R. Conclusion: TMS can effect the diffusion of hydrone in cortex around the infarction focus, then extenuate cerebral edema.

TMS能够在缺血再灌注急性期对大鼠皮层梗塞区水分子的弥散产生影响，使水分子通透性增强，并增强缺血侧大脑半球rCBF，发挥其减轻脑水肿的作用。

Objective: To discuss the diagnostic value of conventional CT in hyperacute cerebral infarction.

目的：探讨常规CT对超急性期脑梗塞的诊断价值。

Objective To evaluate the clinical value of DWI in the diagnosis of hyperacute cerebral infarction and hypertensive encephalopathy.

目的探讨弥散加权像在超急性脑梗塞和高血压脑病诊断中的作用。

Methods: 66 cases of hyperacute cerebral infarction which had complete data were retrospectively analyzed, including clinical manifestations and CT features.

回顾性分析我院资料较完整的66例超急性期脑梗塞的临床表现和CT征象。

Objective To assess the diagnosis value of CT perfusion and CTA in hyperacute cerebral infarction.

目的 探讨螺旋CT灌注成像和CTA对脑梗塞的超急性期诊断、缺血半暗带的判断及判断缺血部位的应用。

Increased water, as in edema, tumor, infarction, inflammation, infection, hemorrhage hyperacute or chronic

增加的水分，如水肿，肿瘤，梗塞灶，炎症，感染，出血。

The conventional CT diagnosis for hyperacute cerebral infarction have difinifive value.

常规CT对超急性期脑梗塞的诊断，具有一定价值。

A total 110 patients with ischemic cerebrovascular diseases is in our group, including 41 case of hyperacute stroke (in 6 hours), patients known with severe infarction, and patients with controversy between clinical presentations and imaging appearances.

本组共包括110例缺血性脑血管病病人，其中包括缺血症状发作6小时之内的41例病人，已知大片脑脑梗塞的病人和临床常规影像检查表现不符的病人。

Average following period was 7.6±3.9 months;EF was 63%±5%;The movement of infarction-related myocardial wall was completely normal in 7 of 9 patients and 2 patients only had slight hypokinesis;Q waves on electrocardialgram was decreased (3/9) or disappeared (6/9),Free-symptom living was 8 patients,only one patient had some tightness on his chest when he did moderate exercis.

除术中、术后各1例并发上消化道大出血外，术中术后无明显心血管并发症(No-Reflow现象、急性血管闭塞、死亡、搭桥术、靶血管再介入治疗)发生。平均随访7.6±3.9月，7例梗塞相关室壁运动完全恢复；Q波导联减少3例，消失6例；EF为63%±5%。

RESULTS :① The left anterior descending branchwas most likely to be damaged;②The specificity between the wall-motion abnormality in A,AS,Apex an d single LAD disease was great (P.05);LAD and left circumflex artery infarcts could lead to AL and I regional wall-motion abnormalities respective l y;contractile function hypokinetic of the single I segment was mostly connected with LCX and right coronary artery injuries;patients with whole left ventricul ar contraction function hypokinetic always suffered from the three-vessel disea se .

结果：①冠状动脉梗塞后左前降支受累最为多见(45%)；②LAD单支病变与前壁、前间隔及心尖部室壁运动异常有关(P.05)。LAD与左回旋支病变，主要为前间隔和下壁运动异常；而单纯的下壁室壁运动异常多为左旋支与右冠状动脉病变引起。3支病变造成心肌运动普遍减低，且以侧壁及前侧壁的室壁运动异常则更为显著(P.05)。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
