概括

一种使用延迟释放直径减小的新型医生修饰内移植 (PMEG) 技术改善了窗体内血管大动脉修复 (FEVAR) 的结果. 这种方法使得顺序目标血管通道,提高复杂的大动脉动脉瘤治疗的安全性和有效性.

科学领域:

血管外科血管外科
血管内修复血管内修复
大动脉动脉瘤治疗方法

背景情况:

医生修改的内脏移植 (PMEG) 是复杂的大动脉动脉瘤的一个选择,不适合标准的窗体内血管大动脉修复 (FEVAR) 或开放式手术.
传统的FEVAR要求对移植物对齐和并发的目标血管管道进行均的直径缩小.
这项研究引入了一种先进的PMEG设计,具有非均的延迟释放直径减小,以改善移植成型和顺序通道.

研究的目的:

描述使用非均约束和延迟释放直径减小的先进PMEG设计的结果.
评估这种新技术对复杂的大动脉动脉瘤的安全性和有效性.
为了证明顺序目标血管通道和支架移植输送的可行性.

主要方法:

患者接受了PMEG-FEVAR,使用经过修改的Cook Zenith Alpha胸内移植与后径缩小.
在移植部署期间,直径减小纽带保持不变,允许接近对大动脉壁的附着.
目标血管被连续道化,桥梁支架移植在释放直径缩小 sutures后一次接送一个.

主要成果:

有203名患有复杂的大动脉动脉瘤的患者接受了治疗 (juxtarenal,pararenal,thoracoabdominal).
100%的成功率在目标血管管道和桥梁支架移植输送.
低并发症率:2.5%的30天死亡率,0%的肢体缺血,1.8%的1年后的形,和7.6%的1年后的动脉瘤相关的重新干预.

结论:

延迟释放直径的减少有效地将PMEG塑造为大动脉解剖,促进顺序目标血管通道.
这种技术在复杂的大动脉内移植中保持了安全性和有效性.
它避免了多个并发的电线,允许较小的对方访问,并降低了对目标船只的风险.

关键词:

动脉瘤是一个动脉瘤.在PMEG中,PMEG是指PMEG.复杂的大动脉动脉瘤.减小直径的缩小直径输内血管移植是输内血管移植.医生修改的内脏移植.

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...

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...
