A Rare Neurologic Complication of Coronary Artery Bypass Graft Surgery: Occipital Infarction with Binocular Amaurosis Fugax
Abstract
Herein, we report a major but
transient neurologic complication occurring early after coronary artery bypass
grafting with cardiopulmonary bypass. In June 2010, a 63-year-old male patient
with a history of unstable angina pectoris and severe coronary stenosis was
admitted for surgery. He also had a past medical history of hypertension,
hyperlipidemia and smoking for 38 years. Preoperative neurological examination
was normal with no visual disturbance or orbital motor dysfunction. Physical
examination of other organ systems were also normal. During the early
postoperative hours, the patient was clinically stable. Direct and consensual
light reflexes were normal bilaterally. Following extubation, bilateral total
loss of vision developed. Computed tomography of the brain at postoperative day
1 revealed a cerebral infarction with surrounding tissue edema in the occipital
lobes. Following the anti-edematous treatment, a gradual improvement of vision
occurred in both eyes. Despite the dramatic improvement in visual functions, a
computed tomography of the brain at postoperative day 12 showed the persistence
of initial radiological findings, suggesting amaurosis fugax, which is
generally defined as a transient monocular visual loss and blindness. Binocular
amaurosis fugax associated with bilateral total blindness due to postoperative
ischemic optic neuropathy has also been described, with an incidence of less
than 0.5%. Some other studies have reported a prevalence rate of 1.3-2% among
patients undergoing open-heart surgery. In any case, bilateral amaurosis fugax
developing as a transient postoperative neurological complication after
coronary artery bypass grafting represents a rare condition. Radiological
imaging studies may sometimes fail to detect the condition and complete
restoration of visual functions may be achieved by appropriate anti-edema
therapy.
