P J Evans, J H Kerr

    British Medical Journal
    |July 26, 1975

    Summary
    This summary is machine-generated.

    Percutaneous arterial cannulation rarely causes ischaemic damage. However, arterial occlusion occurred in 22% of patients, increasing with cannulation duration over six hours.

    Area of Science:

    • Vascular Surgery
    • Interventional Radiology
    • Cardiovascular Medicine

    Background:

    • Percutaneous arterial cannulation is a common medical procedure.
    • Potential complications include ischaemic changes and arterial occlusion.
    • Assessing the incidence and risk factors for these complications is crucial.

    Purpose of the Study:

    • To evaluate the occurrence of ischaemic changes and arterial occlusion after percutaneous arterial cannulation.
    • To identify factors associated with an increased risk of arterial occlusion.

    Main Methods:

    • A survey of 155 patients who underwent percutaneous arterial cannulation.
    • Assessment of clinical signs and patient complaints related to ischaemic damage.
    • Documentation of arterial occlusion and its duration.

    Main Results:

    • No patients exhibited signs or symptoms of ischaemic damage.
    • Arterial occlusion was detected in 33 patients (22%).
    • Occlusion was significantly more frequent after cannulation exceeding six hours (43%) compared to shorter durations (17%).
    • Palpable pulsation persisted in occluded arteries, despite absent blood flow.
    • Blood flow returned in 19 of 33 occluded arteries by follow-up.

    Conclusions:

    • Percutaneous arterial cannulation appears to have a low risk of causing ischaemic damage.
    • Arterial occlusion is a notable complication, with duration of cannulation being a significant risk factor.
    • The presence of palpable pulsation during occlusion suggests potential for recovery.
