Ultrasound Imaging of the Thoracic and Abdominal Aorta in Mice to Determine Aneurysm Dimensions
Published on: March 8, 2019
Summary
Radiologists can assess aortic root size and shape using the periaortic fat layer on lateral chest X-rays. This aids in the early diagnosis and differential diagnosis of aortic root aneurysms.
Area of Science:
- Cardiovascular Imaging
- Radiology
- Thoracic Imaging
Background:
- Aneurysms of the ascending aorta can involve the aortic root.
- Standard chest radiographs may not always detect aortic root dilatation, especially when ascending aorta involvement is minimal.
Purpose of the Study:
- To evaluate the utility of the periaortic fat layer on lateral chest radiographs for assessing the aortic root in patients with ascending aorta aneurysms.
Main Methods:
- Retrospective analysis of 25 cases with ascending aorta aneurysms.
- Assessment of aortic root size and shape by tracing the periaortic fat layer on full-size lateral chest radiographs.
Main Results:
- Dilatation of the aortic root was observed in 19 of 25 cases.
- One aneurysm was confined to the aortic root.
- Two aneurysms were missed on conventional radiography due to minimal ascending aorta dilatation.
Conclusions:
- The periaortic fat layer on lateral chest radiographs can aid in assessing the aortic root.
- This method provides valuable information for the early diagnosis and differential diagnosis of aortic root aneurysms.

01:15Aortic Regurgitation I: Introduction
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...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
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...
01:25Aortic 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...
01:30Aneurysm I: Introduction
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...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
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...
01:26Aneurysm 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...
