Course of the post-catheterization pulseless arm.

P E Braga, A A Salgado, W G Zorn

    The Journal of Cardiovascular Surgery
    |May 1, 1984
    PubMed
    Summary

    Brachial artery thrombosis after cardiac catheterization often resolves spontaneously, with Doppler-derived pressure index improving over 30 days. However, predicting persistent symptoms is difficult, suggesting surgical intervention may be advisable for all cases.

    Area of Science:

    • Vascular Surgery
    • Interventional Cardiology
    • Radiology

    Background:

    • Post-catheterization brachial artery thrombosis is a known complication.
    • The natural course and resolution patterns require further elucidation.
    • Non-operative management strategies are frequently employed.

    Purpose of the Study:

    • To determine the natural course of non-operated brachial artery thrombosis following cardiac catheterization.
    • To assess the changes in ischemic arm pressure index over a one-month period.
    • To evaluate the correlation between pressure index changes and symptom resolution.

    Main Methods:

    • Prospective follow-up study of 45 patients with post-catheterization brachial artery thrombosis.
    • Serial measurements of Doppler-derived pressure index in the ischemic arm.

    Related Experiment Videos

  • Clinical assessment of arm ischemia symptoms at 30 days.

    • Main Results:

    • A gradual increase in the Doppler-derived pressure index was observed, from 0.51 at occlusion to 0.82 at 30 days.
    • The majority of patients (35/45) became asymptomatic within 30 days.
    • No significant difference in pressure index changes was noted between symptomatic and asymptomatic groups, making prediction difficult.

    Conclusions:

    • Non-operated brachial artery thrombosis following cardiac catheterization shows a tendency towards spontaneous resolution and improved perfusion over one month.
    • Predicting which patients will experience persistent arm ischemia symptoms is challenging.
    • Surgical restoration of blood flow should be considered for all patients diagnosed with brachial artery thrombosis post-cardiac catheterization due to the unpredictability of symptom resolution.
