RECOVERY DESPITE IMPAIRED CEREBRAL PERFUSION IN FULMINANT HEPATIC-FAILURE

We report 4 patients with fulminant hepatic failure who developed prolonged intracranial hypertension (> 35 mm Hg for 24-38 h) that was refractpty to standard therapy and associated with impaired cerebral perfusion pressure (< 50 mm Hg for 2-72 h). All survived with complete neurological recovery. Refractory elevation of intracranial pressure and reduced cerebral perfusion pressure are generally thought to contra-indicate liver transplantation in hepatic failure and are indications to withdraw support. Our observations challenge this concept.
