基底节脑出血CT成像中线结构移位与临床

THE SIGNIFICANCE OF MIDLINE STRUCTURE SHIFTING IN THE PATIENTS OF CEREBRAL HEMORRHAGE IN BASAL GANGLIA BY COMPUTERIZED TOMOGRAPHY

对３６例基底节脑出血患者ＣＴ成像中线结构移位与改良爱丁堡－斯堪的那维亚临床神经功能缺损评分作对照研究，结果表明存活组２４例与死亡组１２例中线结构移位有显著差别。移位程度越明显者，病情越严重，病死率增高。对存活组中２３例描述中线结构移位变化的参数与临床神经功能缺损评分作相关分析，进一步表明移位程度与病情严重程度密切相关。

Thirty six patients of cerebral hemorrhage in basal ganglia were studied between midline structure shifting on CT scan and assessment of clinic neurological function, defect(AND). The differences were significant between the following two groups: including in parameter A (the distance from center of hematoma to normal midline), 26.01±6.06mm in survivor group, 21.53±5.03mm in death group; in parameter B (the distance from the farthest point in shifted midline to the normal midline), 3.84±2.66mm in survivor group, 10.32±4.24mm in death group; in parameter C (ratio of the partial length of shifted midline to all length of the normal midline), 0.347±0.136 in survivor group; 0.582±0.082 in death group. Having analized these parameters, the authors found that the mortality rates were 0 and 100% if B was ≤4.0mm and >10.0mm respectively and the mortality rates were 0 and 90% if C was ≤0.30 and >0.50. The authors also found that there was closed correlation between the parameters B or C described midline shifting and AND.
