Coagulopathy in Ruptured or Dissecting Aortic Aneurysms.

J W ten Cate, H Timmers, A E Becker

    The American Journal of Medicine
    |August 1, 1975
    PubMed
    Summary

    Consumption coagulopathy, a clotting disorder, was observed in patients with aortic aneurysms. This finding aids in differentiating aortic aneurysms from similar acute conditions.

    Area of Science:

    • Cardiovascular Medicine
    • Hematology
    • Pathology

    Background:

    • Ruptured or dissecting aortic aneurysms present with acute symptoms that can mimic other serious conditions.
    • Coagulation disorders, such as consumption coagulopathy, can arise in critical vascular events.

    Purpose of the Study:

    • To investigate the presence and characteristics of consumption coagulopathy in patients with aortic aneurysms.
    • To assess the diagnostic utility of this coagulation disorder in differentiating aortic aneurysms.

    Main Methods:

    • Analysis of coagulation parameters in four patients with ruptured or dissecting aortic aneurysms.
    • Measurement of prothrombin time and detection of fibrin/fibrinogen degradation products.
    • Utilized 125I-fibrinogen to assess local accumulation of clotting factors at the lesion site.

    Main Results:

    • All four patients exhibited consumption coagulopathy.
    • Key features included prolonged prothrombin time due to decreased clotting factors and formation of fibrin/fibrinogen degradation products.
    • Increased local radioactivity of 125I-fibrinogen suggested accumulation of clotting factors at the aneurysm site.

    Conclusions:

    • Consumption coagulopathy is a significant finding in patients with aortic aneurysms.
    • Identifying this coagulation disorder can be a valuable diagnostic aid for aortic aneurysms.
    • The findings suggest a potential mechanism involving local accumulation of clotting factors at the site of the arterial lesion.
