- 了解AAA进展对于预测破裂风险和指导治疗决策至关重要.
研究的目的:
- 描述腹腔大动脉动脉瘤 (AAA) 随着时间的推移增长的特征.
- 调查这些生长特征对AAA进展和手术干预的预后价值.
主要方法:
- 对AAA患者 (最大直径≥40毫米) 的前性观察队列研究,每年进行CT成像,持续2年.
- AAA直径以5%的间隔测量,以将增长分为缓慢,边缘和峰值类别.
- 对称性测试和回归模型分析了生长特征的变化,手术门的时间和生物标志物差异.
主要成果:
- 一年后,55名患者表现出边缘生长,20名患者表现出缓慢生长,17名患者表现出峰值生长. 在2年后,增长概况基本保持稳定,观察到从缓慢增长到边缘增长到峰值增长的过渡.

Aneurysm II: Clinical Manifestations and Diagnostic Studies
303
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...

Aneurysm III: Interprofessional Care
255
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
370
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...

Aortic Regurgitation I: Introduction
496
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Atherosclerosis I: Introduction
925
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
418
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
