Ulnar
Neuropathy After Coronary Artery Bypass Surgery

    

  • Swenson
    JD, Bull DA,


    Postoperative Ulnar Neuropathy Associated with
    Prolonged Ischemia in the Upper Extremity During
    Coronary Artery Bypass Surgery

    Anesth
    Analg 85: 1275-1277, 1997


      

    AS
    many as 37% of cardiac surgery patients experience
    an injury to the ulnar nerve.
    A case of ulnar neuropathy, after a period
    [3.5 hours approximately] of decreased arterial
    blood pressure in the right arm is reported.

      

    Man,
    63 years of age, having coronary artery bypass
    surgery, experienced severe right radial artery
    waveform dampening about 10 minutes into surgery. The left radial artery waveform was normal.
    The right radial artery catheter was
    suspected to have a fold at the hub of the catheter. Cardiopulmonary bypass was completed uneventfully, using the left
    radial artery catheter to monitor blood pressure;
    the right radial artery blood pressure remained low.
    On the first postoperative day, the patient
    complained of sensory loss in the right hand, with
    wrist flexion, finger adduction, and abduction
    weakness. After
    3 months, the patient’s strength and sensory
    function returned to near normal; but he reported
    waking up frequently with numbness and weakness. His
    symptoms were reproduced in the left arm when
    brachial artery blood flow was occluded.
    Failure to ensure adequate arterial perfusion
    to the arms, increases the sensitivity of the ulnar
    nerve to ischemia.
