在中国一家三级医院,肺栓塞的计算机断层扫描肺血管扫描 (CTPA) 阳性率为20. 6%. 与深静脉血栓相关的PE病例比单独的PE更严重,PE阳性率没有显著的年度变化.
科学领域:
- 放射学和成像学
- 心血管医学
- 肺部医学
背景情况:
- 计算机断层扫描肺血管扫描 (CTPA) 是诊断肺栓塞 (PE) 的关键.
- 了解CTPA使用趋势和PE阳性对于医疗资源分配和患者管理至关重要.
- 与深静脉血栓 (DVT) 相关的单独PE发生率需要进一步调查.
研究的目的:
- 分析2018年至2021年中国三级医院CTPA利用率和PE阳性率的趋势.
- 为了确定与DVT相关的PE相比,孤立的PE的发生率.
- 探索这些PE类型的临床特征.
主要方法:
- 在2018年1月至2021年12月期间接受CTPA的4378名患者的回顾性分析.
- 每年人口特征和PE阳性率的比较.
- 评估与DVT相关的和孤立的PEs的发生率及其关系.
主要成果:
- 对于PE的整体CTPA阳性率为20. 6% (901/4378名患者).
- 没有观察到性别,年龄或年 PE 阳性率的统计学意义上的差异.
- 与DVT相关的PE比单独的PE更频繁,具有更严重的特征 (中心和多个PE).
结论:
- 在中国的第三级医院队列中,CTPA阳性率为20. 6%,年率稳定.
- 与单独的PE相比,与DVT相关的PE病例表现出更严重的临床特征.
- 这些发现凸显了CTPA在PE诊断中的持续重要性,并强调了不同PE亚型的独特临床特征.
