| Abstract |
|
Central pontine myelinolysis (CPM) is a demyelinating disorder that almost exclusively affects the central portion of basis pontis and occurs in patients with malnutrition, chronic debilitating disorders and electrolyte abnormalities. CPM after liver transplantation is considered that had the relationship to rapid correction of hyponatremia and shift in osmolality. Our first case of 4 liver transplantations altered consciousness at the 5th day after transplantation and did not recover fully until 14 months. At first, atrial fibrillation and atelectasis due to left main broncheal obstruction were thought the causes of impaired consciousness as postoperative hypoxic event. At that time, CT scan showed diffuse brain atropy that suggested previous hepatic encephalopathy and/or hypoxic ischemic encephalopathy. After that, MRI revealed CPM and diffuse cortical atropy. We concluded that CPM associated with rapid correction of hyponatremia perioperatively alter patient's consciousness with hypoxic brain injury. |
