320排CT血管造影对颅内小动脉瘤的诊断及术中应用价值

320-slice CTA in diagnosis of intracranial small aneurysms and intraoperative value analysis

目的:分析探讨320排CT血管造影(CT angiography,CTA)对颅内小动脉瘤的诊断及术中应用价值,为临床提供参考依据。方法:选择某院2012年1月至2016年6月收治的50例经病理证实的颅内小动脉瘤患者作为研究对象,所有患者均采取320排CT检查,并在诊断结束后,对其诊断价值进行探讨。结果:50例颅内小动脉瘤患者的诊断符合率为96.00%,共有48例患者确诊为颅内小动脉瘤,仅有2例患者出现漏诊情况,无误诊情况出现,该诊断结果与病理诊断结果基本一致(P>0.05);CT诊断结果表明,49例患者的颅内小动脉瘤的部位、形态、大小、瘤颈高度及其相邻结构的关系均得到清晰显示,仅有1例患者因颅内小动脉瘤入口过窄、腔内部分血栓导致未显影。结论:320排CTA对颅内小动脉瘤的临床确诊率较高,且具有非创伤、快捷方便的优点,可为临床治疗方案提供科学准确的影像依据,值得在临床实践中应用和推广。

Objective To investigate the values of 320-slice CTA for the diagnosis and intraoperative application of intracranial small aneurysms. Methods Fifty patients with pathologically confirmed intracranial small aneurysms were selected as the study subjects from January 2012 to June 2016. All the patients underwent 320-slice CT examination, and then the diagnostic values of 320-slice CT were discussed. Results Totally 48 patients were confirmed with intracranial small aneurysms and the diagnostic accordance rate was 96%, and there was missed diagnosis in 2 patients and no patients mis-diagnosed. The results by320-slice CTA were mostly consistent with those by pathological examination. 320-slice CTA displayed the site, shape, size,aneurysm neck height and adjacent structure of intracranial small aneurysms clearly in 49 patients, and undeveloped aneurysms due to narrow entrance or intraluminal thrombosis occurred in 1 patient. Conclusion 320-slice CTA gains advantages in diagnosing intracranial small aneurysms such as non invasion and high convenience and provides basis for clinical treatment,and thus is worthy promoting clinically.
