概括
真正的动脉动脉瘤 (RAA) 很少生长并且不会破裂,在93%的病例中显示稳定性. 这表明,对于无症状的RAA来说,不太频繁的监测可能是适当的.
科学领域:
- 血管外科 血管外科
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 真正的动脉动脉瘤 (RAA) 是一种罕见的血管形.
- 目前对无症状RAA的监测协议没有标准化.
- 了解RAA生长模式对于优化患者管理至关重要.
研究的目的:
- 在多中心患者队列中确定真正的动脉动脉瘤 (RAA) 的生长轨迹.
- 根据观察到的生长模式,开发无症状RAA的后续算法.
主要方法:
- 在15年内,在三个中心的155名患者中,对171名真正的RAA进行了回顾性分析.
- 横截面成像被用于测量最大动脉瘤直径在初始诊断和随访期间.
- 两个独立的放射科医生评估了生长模式.
主要成果:
- 93%的RAA (159/171) 在平均61个月的随访期间表现出稳定的尺寸.
- 整体平均增长率低至0.015厘米/年.
- 在诊断时测量≤1.5厘米的RAA表现出明显较低的生长率 (0.01厘米/年).

Aneurysm III: Interprofessional Care
30
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...

Imaging Studies VII: Vascular Imaging
66
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

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 I: Introduction
31
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...
