多层螺旋CT血管成像对蛛网膜下腔出血的病因诊断价值

Diagnostic value of multi-slice spiral CT angiography in etiological diagnosis of subarachnoid hemorrhage

目的探讨多层螺旋CT血管成像(CTA)对自发性蛛网膜下腔出血(SAH)的病因诊断价值。方法选取2011—2012年SAH患者50例,所有患者均在CTA后实施数字减影脑血管造影(DSA)检查,对二者结果进行对比分析。结果 CTA正确检出率(以DSA结果为标准,98%,49/50)与DSA比较,差异无统计学意义(P>0.05);CTA组瘤体体积及瘤颈宽度检测结果与DSA检测结果比较,差异无统计学意义(P>0.05)。结论 CTA在SAH病因中诊断价值较高,值得应用。

Objective To investigate the value of multi-slice spiral CT angiography （CTA） in the etiological diagnosis of spontaneous subarachnoid hemorrhage（SAH）. Methods 50 patients with SAH enrolled in this hospital from 2011 to 2012 were selected and examined by digital subtraction angiography （DSA） after CTA. The results of DSA and CTA were compared. Results WitJa the result （98%, 49/50） measured by DSA as the standard, the correct detection rate had no statistical difference between CTA and DSA（P〉0.05）. The lump volume and the lump neck breadth measured by CTA and DSA had no statistically siginffi- cant difference （P〉0.05）. Conclusion CTA has the higher value in the etiological diagnosis of SAH and is worth being used.
