Abstract:
Abstract Abdominal aortic aneurysm (AAA) is the most common arterial dilatation disease. Computed tomographic angiography has been used all the time in the diagnosis of AAA. Applying the techniques in AAA, we can not only locate the position of AAA, but also classify it, and provide more valuable information for clinicians. Currently, post-processing methods include MPR, CPR, VR. These methods have their own advantages.Keywords:

目的
探讨超声引导下静脉留置针穿刺在神经外科CT血管造影(CTA)检查中的应用价值。
方法
选择湖州市第一人民医院神经外科2016年8月至2017年7月收治的需行CTA检查而置入20 G外周静脉留置针的患者180例为研究对象，采用随机数字表法分为对照组90例和观察组90例。对照组采用常规技术置入留置针，观察组将超声引导技术应用于静脉留置针置入的全过程，包括操作前血管的评估、留置针型号的选择、操作时的实时引导及操作后的确认。比较两组穿刺成功率、检查完成率、并发症发生率、患者满意度。
结果
观察组一次穿刺置管成功率为97.8%(88/90)，检查完成率为93.3%(84/90)，并发症发生率为3.3%(3/90)，对照组分别为81.1%(73/90)、78.9%(71/90)、15.6%(14/90)，两组差异均有统计学意义(χ2＝13.239、7.850、7.860，均P<0.01)；观察组患者非常满意率为95.6%(86/90)，高于对照组的75.6%(68/90)(χ2＝14.565，P<0.01)。
结论
超声引导下静脉留置针穿刺是一种快速、有效、安全的护理操作技术，有效地提高了神经外科护理的工作效率，使患者安全的完成检查。
