Summary
Abdominal aortic aneurysm (AAA) volume measurement shows promise for surveillance, particularly after EVAR. However, current studies lack standardized protocols, making clinical relevance unclear.
Area of Science:
- Vascular Surgery
- Medical Imaging
- Biomedical Engineering
Background:
- Abdominal aortic aneurysm (AAA) diameter measurement is standard, but may fail in certain surveillance scenarios.
- AAA volume measurement is emerging as a potential complementary surveillance method.
Purpose of the Study:
- To systematically review and analyze studies comparing AAA diameter and volume measurements.
- To assess the diagnostic and prognostic value of AAA volume versus diameter.
Main Methods:
- Systematic literature search of PubMed, Cochrane, and EMBASE databases up to December 2022.
- Inclusion of studies in English, German, and Russian, assessing AAA diameter and volume.
- Quality assessment of 19 included studies (n=1690) using MINORS criteria.
Main Results:
- Seventeen of 19 included studies favored AAA volume measurement.
- Significant heterogeneity in methodologies and lack of standardized protocols for both diameter and volume measurements were noted.
- This heterogeneity hindered definitive interpretation of the results.
Conclusions:
- The clinical utility of AAA volume measurement remains uncertain.
- Volumetric changes in AAA show promising results, especially for follow-up after endovascular aneurysm repair (EVAR).
- Standardization of measurement protocols is crucial for future research and clinical application.

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.

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...

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...
