概括
在内血管动脉瘤修复过程中,图像融合 (IF) 指导显著减少了手术时间,化对比物质 (ICM) 的使用和辐射暴露. 这项研究还表明,在MRA-IF指导的EVAR中,零ICM使用的可行性,特别是在高风险患者中.
科学领域:
- 血管外科
- 医学成像
- 干预性放射学
背景情况:
- 内血管动脉瘤修复 (EVAR) 与辐射暴露和含对比物质 (ICM) 相关的并发症相关.
- 尽量减少这些风险对于患者安全和改善EVAR结果至关重要.
研究的目的:
- 在EVAR中评估图像融合 (IF) 指导的临床益处.
- 评估零ICM在磁共振血管学 (MRA) -IF引导的EVAR的可行性和结果.
主要方法:
- 在2018年1月至2024年12月期间对54名患者进行了回顾性研究.
- 患者被分为IF指导的EVAR和传统的EVAR组.
- 在选择的患者中,使用手术前的MRA与活体光学和对比度增强的超声波进行零ICM EVAR.
主要成果:
- 与传统的EVAR相比,IF指导的EVAR显著减少了手术时间 (53. 8比97. 8分钟),ICM使用量 (70. 0比150. 0毫升) 和辐射暴露量 (158. 5比272. 0单位).
- 在所有IF指导的EVAR案例中取得了技术上的成功.
- 五名患有功能衰竭或ICM过敏的患者在没有使用ICM的情况下进行了成功的EVAR.
结论:
- 图像融合指导在减少手术时间,ICM使用和EVAR期间的辐射暴露方面具有显著的优势.
- 在MRA-IF指导的EVAR中,零ICM的使用是可行的和安全的,特别是对于ICM的禁忌患者.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
