概括

一个新的基于体积的参数,理想的WEB-动脉瘤体积 (iWAVe) 比率,改善了Woven EndoBridge (WEB) 对动脉瘤的设备选择. 这种方法提高了尺寸的准确性,可能减少在治疗期间更换设备的需要.

科学领域:

内血管神经外科手术血管内血管神经外科
医疗器械工程医疗器械工程
放射学放射学是一门学科.

背景情况:

织成的EndoBridge (WEB) 设备用于治疗宽两叉动脉瘤.
精确的尺寸 WEB 设备对于成功的治疗结果至关重要.
目前基于动脉瘤尺寸的尺寸测量方法可能会导致低于最佳的设备选择和交换.

研究的目的:

引入和评估一个新的基于体积的参数,理想的WEB-动脉瘤体积 (iWAVe) 比率,以优化WEB设备大小.
为了比较iWAVe比率与传统大小测量方法的有效性.

主要方法:

对接受宽两动脉瘤治疗的患者的回顾性审查 (2021年1月 - 2022年5月).
自动计算动脉瘤体积和测量预期装置位置.
定义WAVe比率 (动脉瘤体积与WEB体积) 和二分化成成功和不成功的大小组.

主要成果:

在成功组中,iWAVe比率的中位数为1.0 (范围为0.76-1.31),在失败组中为1.27 (0.58-1.89).
在0.90-1.16之间的iWAVe比率与成功大小的概率>80%有关.
该iWAVe比率表现出0.60的灵敏度和1.00的特异性,用于最佳的首次尝试大小.

结论:

iWAVe比率提供了一个有希望的基于体积的方法来提高设备尺寸的精度.
将动脉瘤宽度与iWAVe比率相结合可以指导临床决策,以进行最佳的选择.
这一新型参数可能会减少设备交换的发生率,并提高治疗效率.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
