Aneurysm III: Interprofessional Care01:26

Aneurysm 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...

Aneurysm 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...

Aneurysm 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...
Aortic Regurgitation I: Introduction01:15

Aortic 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...

Aortic 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...
Aortic Regurgitation III: Medical Management01:25

Aortic 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...

Summary
This summary is machine-generated.

Saccular aortic aneurysms (SAAs) do not grow faster than fusiform ones, but many still require surgery. Regular monitoring is crucial for managing SAA, guiding future treatment strategies.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Medicine
  • Radiology

Background:

  • Saccular aortic aneurysms (SAAs) are often repaired due to perceived rupture risk.
  • Evidence for a more aggressive natural history of SAAs compared to fusiform aneurysms is limited.

Purpose of the Study:

  • To evaluate the natural history and growth rate of saccular aortic aneurysms.
  • To determine predictors of SAA growth and the need for surgical intervention.

Main Methods:

  • Retrospective review of CT scans for SAAs diagnosed between 2003-2011.
  • Analysis of patient demographics, clinical course, and SAA evolution via follow-up CT.
  • Multivariate analysis to identify predictors of aneurysm growth rate.

Main Results:

  • 322 SAAs in 284 patients were identified; 39.8% underwent surgical repair.
  • Mean SAA diameter was 5.0±1.6 cm, larger in repaired (5.4±1.4 cm) vs. unrepaired (4.4±1.1 cm) aneurysms.
  • Aneurysm growth rate was 2.8±2.9 mm/yr; decreased calcium burden and increased patient age predicted growth.

Conclusions:

  • SAAs did not demonstrate a higher growth rate than fusiform aneurysms.
  • Despite slower growth, a significant proportion of SAAs ultimately require surgical intervention.
  • Clinical and radiological follow-up is essential for SAA management, with further research needed for optimal treatment strategies.
