The Annals of Thoracic Surgery
|May 1, 1979
Summary
Computed tomography (CT) accurately diagnoses abdominal aortic aneurysms, even without calcification. This imaging technique provides precise measurements and better visualization of aortic lumen and thrombus compared to other methods.
Area of Science:
- Medical Imaging
- Radiology
- Vascular Surgery
Background:
- Abdominal aortic aneurysms (AAAs) pose significant diagnostic challenges.
- Accurate imaging is crucial for timely intervention and patient management.
Purpose of the Study:
- To evaluate a new computed tomography (CT) technique for diagnosing abdominal aortic aneurysms (AAAs).
- To assess the accuracy of CT measurements compared to surgical findings.
- To determine the utility of contrast-enhanced CT in visualizing aortic lumen and thrombus.
Main Methods:
- Experience with 58 patients undergoing CT for AAA diagnosis.
- Comparison of CT measurements with intraoperative findings in 37 patients.
- Evaluation of contrast enhancement for lumen and thrombus delineation.
Main Results:
- CT clearly demonstrated the abdominal aorta in all patients, irrespective of calcification.
- CT measurements of maximal dilatation correlated highly with operative measurements, proving most accurate.
- Contrast-enhanced CT effectively delineated the aortic lumen and intraaneurysmal thrombus, surpassing other methods.
Conclusions:
- CT is a highly accurate and reliable method for diagnosing abdominal aortic aneurysms.
- Contrast-enhanced CT offers superior visualization of intraluminal structures.
- CT serves as a valuable screening tool and aids in differential diagnosis and monitoring of AAAs.

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...
