概括
脏血管髓脂瘤 (AML) 构成出血的风险. 内瘤动脉瘤的存在,而不是瘤的大小,是破裂的关键预测因素,指导选择性动脉栓塞 (SAE) 决策.
科学领域:
- 干预性放射学 干预性放射学
- 血管外科 血管外科
- 在瘤学瘤学.
背景情况:
- 脏血管质瘤 (AML) 是血管瘤,具有危及生命的出血风险.
- 选择性动脉栓塞 (SAE) 是对症状性AML的有效治疗方法.
- 鉴定高风险AML进行干预是具有挑战性的,因为无症状呈现和历史依赖大小标准.
研究的目的:
- 为了评估入内瘤动脉瘤的存在和大小,作为脏AML中自发破裂的预测因素.
- 为了改善患者选择SAE超出传统的基于大小的指导方针.
- 为脏AML管理提供更准确的风险分层.
主要方法:
- 在10年内对27名用SAE治疗的脏AML进行回顾性分析.
- 两个放射科医生对CT和血管图像的独立审查.
- 统计分析以确定自发破裂和出血的预测因素,重点关注动脉瘤的存在和大小.
主要成果:
- 在破裂和未破裂的AML之间没有发现显著的尺寸差异.
- 80%的破裂的AML至少含有一次入瘤动脉瘤,相比之下,27%的未破裂的AML (P <0.05).
- 破裂性AML的平均动脉瘤大小略大一些,但这没有达到统计学意义.
结论:
- 内瘤动脉瘤的存在是脏AML自发破裂和出血的重要预测因素.
- 内动脉瘤应该是选择SAE患者的主要考虑因素.
- 这一发现增强了脏AML管理的风险分层,超越了单纯的尺寸.

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...

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...

External Anatomy of the Kidney

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Aneurysm I: Introduction
13
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...
