Indications for angiography in extremity trauma.

S J McCorkell, J D Harley, M S Morishima

    AJR. American Journal of Roentgenology
    |December 1, 1985
    PubMed
    Summary

    Physical examination effectively predicts negative angiograms in trauma patients. Pulse abnormalities or cold limbs strongly correlate with significant vascular injuries across various trauma types.

    Area of Science:

    • Trauma Surgery
    • Vascular Surgery
    • Diagnostic Imaging

    Background:

    • Traumatic injuries frequently involve vascular structures.
    • Accurate assessment of vascular injury is critical for patient outcomes.
    • Angiography is a key diagnostic tool in evaluating potential vascular damage.

    Purpose of the Study:

    • To evaluate the diagnostic utility of angiography in extremities with trauma.
    • To correlate angiographic findings with clinical presentation and mechanism of injury.
    • To determine the predictive value of physical examination findings for vascular injury.

    Main Methods:

    • Retrospective review of 119 extremity angiograms in patients with gunshot wounds, lacerations, and blunt trauma.
    • Correlation of angiographic findings with clinical history and physical examination.
    • Comparison of pre-procedure clinical assessment with post-procedure angiographic results.

    Main Results:

    • Angiograms performed solely due to proximity of injury showed no major arterial injuries.
    • Significant vascular abnormalities were found in 44% of gunshot wounds, 80% of knife injuries, and 67% of blunt trauma when other indications were present.
    • Pulse abnormalities or cold limbs were most frequently associated with positive angiographic findings (74% of cases).

    Conclusions:

    • Physical examination is a sensitive and effective tool for identifying patients unlikely to have vascular injuries.
    • Clinical assessment can help guide the judicious use of angiography in trauma patients.
    • Prompt identification of vascular abnormalities through clinical signs improves management decisions.
