【摘要】目的:对比CT血管造影(CTA)与数字减影脑血管造影(DSA)检查在自发性蛛网膜下腔出血(sSAH)诊断中的价值与优势。方法: 对我科2006年7月~2008年6月收治的36例sSAH患者均进行脑CTA及 DSA配对检查。结果:36例中,%(26/36);%(27/36),两者无明显差别。其中2例多发性动脉瘤患者中,CTA扫描只检出1例,而DSA检查2例均被检出。结论:CTA扫描具有三维重建图像特征,安全、准确、快捷、经济,可作为sSAH早期诊断的首选方法。必要时可根据平扫结果进一步选择扫描基线降至枕骨大孔或上移扫描范围,进而提高阳性率,为外科手术定位切除范围提供了显著优势。

[ABSTRACT] Objective: pare the application of CT angiography (CTA) and digital subtraction angiography (DSA) in the early diagnosis of spontaneous subarachnoid hemorrhage(s
SAH). Methods: Employed paring examination to 36 sSAH patients during July 2006 to June 2008 by CTA and DSA. Results: Positive rate of CTA examination was % (26/36), with three dimension reconstruction, while positive rate of DSA was % (27/36). The difference between two scanning methods was insignificant. 1 case with multiple aneurysms was missing by CTA scanning. Conclusion: CTA is safe, accurate, convenient and economical. It can be the first choice for early diagnosis of sSAH, and is helpful for surgical localizing.

自发性蛛网膜下腔出血(spontaneoas subarachnoid hemorrhage, sSAH) 是神经外科较常见的疾病,是颅内动脉瘤(AN)及动静脉畸形(AVM)的主要并发症,具有较高的致死率和致残率[1]。早期发现及治疗,特别是针对病因治疗对患者的病程转归
