- 生物医学工程 生物医学工程
背景情况:
- 血管内动脉瘤修复 (EVAR) 后超出囊径的形态变化尚未完全理解.
- 甲状腺延伸和扭曲度的纵向变化需要进一步的表征.
研究的目的:
- 为了评估经过EVAR后的纵向大脑垂体延伸和扭曲.
- 为了确定这些形态变化的预后价值,用于内孔和囊动力学.
主要方法:
- 来自529名EVAR患者的CT血管图分析,随访时间中位数为46个月.
- 使用标准化协议测量中心线和欧几里德长度和曲率指数.
- 应用混合效应模型用于时间趋势和后勤模型用于内泄漏预测,调整后续持续时间和敌对部解剖学.
主要成果:

Aneurysm III: Interprofessional Care
233
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
176
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...
