The coagulopathy associated with aortic aneurysms.

E P Gétaz, J H Louw

    Postgraduate Medical Journal
    |November 1, 1977
    PubMed
    Summary

    Ruptured abdominal aortic aneurysms have a high mortality rate (56%), especially in shocked patients. Early platelet count and coagulation screening are crucial for managing abdominal aortic aneurysms and improving patient outcomes.

    Area of Science:

    • Vascular Surgery
    • Aortic Aneurysm Research
    • Coagulation Medicine

    Background:

    • Abdominal aortic aneurysms (AAAs) pose significant health risks, particularly when ruptured.
    • Understanding the impact of coagulation status on AAA outcomes is critical for surgical management.

    Purpose of the Study:

    • To analyze the outcomes of patients undergoing surgery for abdominal aortic aneurysms.
    • To investigate the role of platelet counts and coagulation abnormalities in ruptured AAAs.
    • To recommend diagnostic and therapeutic strategies for AAA patients.

    Main Methods:

    • Retrospective review of 84 patients with abdominal aortic aneurysms.
    • Analysis of patient presentation, including ruptured versus unruptured aneurysms.
    • Evaluation of platelet counts, coagulation screening results, and mortality rates.

    Main Results:

    • Thirty-two percent of patients presented with ruptured aneurysms, resulting in a 56% mortality rate.
    • Shocked patients with ruptured aneurysms exhibited the highest mortality.
    • Coagulation abnormalities (low platelets, abnormal clotting) were prevalent in ruptured AAA cases, with 70% mortality in those with clotting issues.

    Conclusions:

    • Ruptured abdominal aortic aneurysms are associated with high mortality, emphasizing the need for prompt intervention.
    • Comprehensive pre-operative assessment including platelet count and coagulation screening is essential for all AAA resection candidates.
    • Therapeutic strategies should focus on correcting coagulation system abnormalities to improve patient survival.
