概括

经过修改的使用无张力接的本塔尔手术在动脉根置换后对感染性内心炎患者显示出有前途的结果,死亡率低且没有复发.

科学领域:

心血管外科心血管外科
传染性内心炎感染性内心炎
大动脉根的替代术

背景情况:

急性传染性内心炎 (IE) 在大动脉根置换后 (ARR) 提出了重大挑战.
周环环状并发症和大动脉根衰变风险会使预后复杂化.
为了解决这些问题,开发了一种经过修改的Bentall手术,具有无张力近端合.

研究的目的:

为了评估经过ARR后IE患者修改的本塔尔手术的结果.
评估死亡率,再干预率和内心炎复发率.
为了确定无紧张接技术的安全性和有效性.

主要方法:

在2014-2021年间对20名IE患者进行ARR后期分析.
使用了经过修改的本塔尔技术,使用了植入物,伪鼻腔和门假肢.
采用无张力近道接方法,将5mm的管子保持在假肢下面.

主要成果:

平均EuroSCORE II的比率为36.0%,为36.0%. 65%的人患有围周并发症,25%的人患有严重的大动脉反.
30天的死亡率为10.0%. 一年和六年生存率分别为90.0%和85.0%.
平均随访时间为42个月;没有观察到内心炎复发或重新干预. 在没有重新干预的情况下,发生了两例Bentall消声症.

结论:

经过修改的Bentall技术与无张力近端接提供了令人鼓舞的结果,在IE患者中进行重复ARR.
这种技术似乎可以减少并发症并改善生存率.
需要进一步的研究来证实这些发现在更大的队列中.

关键词:

这是本塔尔程序.动脉动脉根的动脉动脉根.传染性内心炎是一种感染性内心炎.

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...

Endocarditis I: Introduction

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
