概括

对于腹腔大动脉动脉瘤 (AAA) 的内血管动脉瘤修复 (EVAR) 后的开放性手术转换 (OSC) 往往是2型内泄症的指示. 在接受OSC的患者中,破裂显著增加了30天的死亡率.

科学领域:

血管外科血管外科
血管内修复血管内修复
腹腔大动脉动脉瘤是什么?

背景情况:

内血管动脉瘤修复 (EVAR) 是对腹腔大动脉瘤 (AAA) 的常见治疗方法.
并发症和长期失效可能需要开放式手术转换 (OSC).

研究的目的:

评估AAA的EVAR后的OSC的指示和结果.
确定OSC后死亡的风险因素.

主要方法:

从13个日本血管中心 (2006-2024) EVAR后接受OSC的208名患者的回顾性分析.
收集的数据包括基线特征,OSC的指示,程序细节和结果.
主要终点:30天死亡率. 二级终点:整体存活率,动脉瘤相关存活率,不需要再治疗.

主要成果:

最常见的表示 (47.1%) 是2型内孔,囊囊扩大.
38名患者 (18.3%) 呈现破裂,48名患者 (23.1%) 接受了紧急的OSC.
30天死亡率总体为4.3%,但破裂病例为13.2%. 破裂是30天死亡率的重要风险因素 (HR 5.93).
10年整体存活率为58.4%,不需要再治疗的比例为87.5%.

结论:

在EVAR之后,2型内皮漏洞是OSC的主要征兆.
在OSC发生时的动脉瘤破裂显著增加了30天死亡率.
需要进一步的研究来优化OSC的选择性指示,并防止治疗延迟.

Aneurysm III: Interprofessional Care

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 II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
