Abdominal aortic aneurysms: diagnosing and treating on time.

B A Perler, J F Burdick

    Geriatrics
    |February 1, 1985
    PubMed
    Summary

    The idea of a "safe" aneurysm is false, as even small ones rupture frequently. Many abdominal aortic aneurysms are silent before a fatal rupture occurs.

    Area of Science:

    • Vascular Surgery
    • Radiology
    • Medical Diagnostics

    Background:

    • The concept of a "safe" aneurysm, particularly abdominal aortic aneurysms (AAAs), is increasingly challenged by new evidence.
    • A significant proportion of patients with AAAs remain asymptomatic until rupture, leading to high mortality rates.
    • Rupture incidence, even in smaller aneurysms, is a critical concern in vascular health.

    Purpose of the Study:

    • To challenge the notion of "safe" aneurysms and highlight the high rupture risk.
    • To emphasize the asymptomatic nature of many abdominal aortic aneurysms prior to catastrophic events.
    • To evaluate the utility of lateral lumbosacral spine films for rapid aneurysm assessment.

    Main Methods:

    • Review of recent evidence regarding aneurysm rupture incidence.
    • Analysis of patient presentation data for abdominal aortic aneurysms, focusing on asymptomatic cases.
    • Assessment of the effectiveness of lateral lumbosacral spine radiography with bone technique for aneurysm detection and size estimation.

    Main Results:

    • Recent evidence refutes the concept of a "safe" aneurysm, indicating a high rupture incidence even in small aneurysms.
    • Up to 50% of patients with abdominal aortic aneurysms are asymptomatic before rupture and death.
    • Lateral lumbosacral spine films with bone technique are effective for rapid aneurysm evaluation, detecting sufficient calcium in approximately 75% of AAAs for accurate size estimation.

    Conclusions:

    • The notion of a "safe" aneurysm is a dangerous fallacy.
    • Early detection and intervention are crucial given the high rate of asymptomatic presentation and rupture risk.
    • Lateral lumbosacral spine radiography offers a practical and accurate method for the rapid assessment of abdominal aortic aneurysms.
