与心脏手术中的右半径方法 (RRA) 相比,左半径方法 (LRA) 显著减少了X射线辐射暴露,包括光镜时间和剂量区域产品. 这一发现支持LRA尽量减少患者和操作员的辐射剂量.
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 医学物理 医学物理
背景情况:
- 穿皮冠状动脉手术 (PCP) 涉及辐射暴露,需要策略来最大限度地减少剂量.
- 选择放射性动脉通道 (左侧或右侧) 可能会影响患者和操作人员的辐射暴露.
- 现有证据比较左半径方法 (LRA) 和右半径方法 (RRA) 之间的辐射剂量是多样化的.
研究的目的:
- 进行一项元分析,比较PCP期间LRA和RRA之间的X射线辐射暴露.
- 量化光镜时间 (FT),剂量面积乘积 (DAP) 和累积空气克尔玛 (CAK) 的差异.
- 评估对操作员辐射剂量和DAP正常化胸部剂量的影响.
主要方法:
- 在Scopus,Embase,PubMed和Web of Science数据库中进行系统的文献搜索,直到2025年7月.
- 包括19个随机对照试验 (RCT),涉及9443名参与者.
- 进行元分析以确定辐射暴露参数的标准化平均差异 (SMD) 和置信区间 (CI).
主要成果:
- 与RRA相比,LRA显著减少了FT (SMD 0.105,p=0.003) 和DAP (SMD 0.09,p=0.017) 的使用.
- 在LRA和RRA (SMD 0.067,p=0.055) 之间没有观察到累积空气克尔玛 (CAK) 的显著差异.
- 与RRA相比,LRA显著降低了操作员辐射剂量 (SMD 0.297,p=0.034) 和DAP正常化的胸部剂量 (SMD 0.392,p=0.000).
结论:
- 左半径方法与显著降低光镜时间,剂量区域产品和PCP期间操作员辐射暴露有关.
- 对于患者和医疗保健专业人员来说,LRA在减少辐射剂量方面具有潜在的好处.
- 进一步的研究可能会探索与LRA与RRA相关的长期影响和患者结果.

Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
