概括

在内血管大动脉修复 (EVAR) 中使用的形状记忆聚合物 (SMP) 插头可促进动脉瘤囊血栓形成和回归. 一年后的随访显示,囊缩率很高,没有内脏泄漏或重新干预.

科学领域:

血管外科血管外科
医疗器械技术医疗器械技术
生物材料是一种生物材料.

背景情况:

动脉瘤囊的行为影响了血管内主动脉修复 (EVAR) 后的长期存活率和再干预率.
在EVAR期间对动脉瘤囊的积极管理越来越感兴趣.
形状记忆聚合物 (SMP) 插头为动脉瘤囊栓塞提供了一种新的方法.

研究的目的:

调查SMP插头在EVAR期间对动脉瘤囊栓塞的实用性.
评估SMP插头在促进囊性血栓形成和回归方面的安全性和有效性.
为了评估EVAR的短期结果,使用SMP插头进行预防性囊栓塞.

主要方法:

对从2022年2月到2024年1月使用SMP插头进行EVAR的患者进行了回顾性研究.
对安全结果的评估,包括意外栓塞和囊孔.
评估疗效结果:动脉瘤体积和直径的变化,内脏泄漏和使用放射学软件的重新干预.

主要成果:

分析了29名患者的1年随访数据.
没有观察到内脏泄漏,再干预或不良安全事件.
中位数动脉瘤体积显示了17%的回归,中位数直径在1年内减少了6mm.
67%的患者表现出超过10%的动脉瘤体积回归;55%的患者表现出直径回归.

结论:

使用SMP插头进行预防性动脉瘤囊栓塞是安全有效的,可诱导囊囊血栓形成和回归.
一年后的随访表明,囊回归率高,没有内脏泄漏,没有重新干预.
由于其生物降解性和缺乏CT工件,SMP插头是传统栓塞材料的有希望的替代品.

Aneurysm IV: Nursing Management

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

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. This...

Aneurysm I: Introduction

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
