概括
计算机断层扫描血管造影 (CTA) 是诊断脑死亡 (BD) 的一个有用的确认性研究. 这项研究证实了德国CTA协议在现实世界临床实践中的可用性.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 关键护理医学 关键护理医学
背景情况:
- 计算机断层扫描血管造影 (CTA) 被探索为诊断脑死亡 (BD) 的确认性研究 (CS).
- 缺乏关于CTA参数和BD诊断标准的国际共识.
- 2015年,CTA协议被引入德国BD指南中.
研究的目的:
- 调查CTA在脑死亡确定中的实施,结果和影响.
- 分析CTA在德国指南中引入后的前四年中在成年人中使用的情况.
主要方法:
- 分析了来自德国一个器官采购组织的大脑死亡检查的综合数据集.
- 审查了来自5152名临床上缺失大脑功能的患者的数据.
- 包括来自676家医院的1272次CTA检查.
主要成果:
- 在四年内,CTA使用率从17.2%增加到29.7%,取代了其他确认性研究,但没有增加整体频率.
- 技术故障很少发生 (0.9%),其中89.3%的研究是积极的.
- 阴性CTA结果与二次脑损伤,较长时间的BD综合征或不可靠的临床评估有关. 中位数诊断时间较长的CTA (2.6h) 与其他CS (1.6h). CTA没有影响BD确认率或小医院的入口.
结论:
- CTA扩大了成人脑死亡诊断中确认性研究的选择.

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
