Forearm arterial injuries.

R H Gelberman, J P Blasingame, A Fronek

    The Journal of Hand Surgery

    Summary
    This summary is machine-generated.

    Forearm arterial injuries alone cause minor vascular changes. Combined nerve and artery injuries lead to significant hand vascularity issues and disabling symptoms, especially with median nerve involvement.

    Area of Science:

    • Vascular Surgery
    • Neurology
    • Peripheral Vascular Disease

    Background:

    • Forearm injuries can involve arteries, nerves, or both.
    • Understanding the distinct and combined effects of these injuries is crucial for patient outcomes.
    • Cold exposure can exacerbate symptoms of vascular compromise.

    Purpose of the Study:

    • To evaluate the hemodynamic effects of isolated arterial injuries versus combined arterial and neurological injuries in the forearm.
    • To correlate vascular alterations with symptoms of hand ischemia and cold intolerance following injury.
    • To assess the impact of arterial injuries on recovery from associated nerve injuries.

    Main Methods:

    • Noninvasive peripheral vascular studies were performed on 50 subjects.
    • Subjects included patients with isolated arterial lacerations, isolated nerve lacerations, combined injuries, and controls.

  • Vascular studies were correlated with symptoms during controlled cold-environment exposure.

    • Main Results:

    • Unrepaired arterial injuries caused modest vascular changes but few ischemic symptoms or cold intolerance.
    • The intact contralateral artery showed increased flow velocity after unilateral injury.
    • Combined nerve and artery injuries resulted in the most significant vascular alterations and disabling symptoms, particularly median nerve and artery injuries.

    Conclusions:

    • Isolated arterial injuries have limited long-term impact on hand vascularity and nerve recovery.
    • Combined injuries, especially involving the median nerve and its associated artery, lead to severe functional deficits.
    • Early and comprehensive assessment of both vascular and neurological components is vital for managing forearm injuries.
