概括

针对II型内腔漏洞 (T2E) 的手术内对比增强超声波 (CEUS) 引导栓塞显示,在第一次尝试后,技术成功率为50%. 重复栓塞提高了成功率至77%,负CEUS与更好的囊稳定相关.

科学领域:

血管外科血管外科
干预性放射学干预性放射学
医疗成像医学成像

背景情况:

二型内泄漏 (T2E) 是内血管动脉瘤修复后的常见并发症.
持续的T2E可能导致动脉瘤囊扩大和破裂.
术内成像对于评估栓塞成功至关重要.

研究的目的:

评估手术内对比增强超声波 (CEUS) 在指导II型内泄 (T2E) 栓塞的有效性.

主要方法:

使用了一种涉及跨动脉或跨腰部接入和栓塞的标准化协议.
运营内部的CEUS被用来评估技术成功,定义为内漏排除.
在26名连续的患者中,Onyx® 18和线圈被用于栓塞.

主要成果:

初始栓塞在50%的患者中取得了技术上的成功,CEUS上标记了残留T2E.
通过CEUS指导的额外栓塞尝试将技术成功率提高到77%.
阴性完成CEUS与较高的动脉瘤囊稳定率 (80%) 相关,并且不需要进一步的T2E干预.

结论:

术内CEUS在评估T2E栓塞方面是有效的.
由CEUS指导的多次栓塞尝试可以提高技术成功率.
在T2E栓塞后的负完成CEUS预测了有利的结果和袋子稳定.

关键词:

Imaging Studies for Cardiovascular System II:Types of Echocardiography

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...
