title: Intracerebral hemorrhage after liver transplantation.
abstract: We report 5 patients with intracerebral hemorrhage after orthotopic liver transplantation (OLT) and identify the possible risk factors. Between November 1991 and April 1999, 75 adult patients received 77 orthotopic liver transplants at Queen Mary Hospital, Hong Kong. Five patients (6.5%) developed intracerebral hemorrhage postoperatively. Clinical and laboratory data were reviewed, and potential risk factors were analyzed. The 5 patients developed intracerebral hemorrhage within 40 days (range, 1 to 37 days; median, 4 days) after OLT. The mortality rate was 80% (4 of 5 patients). The intraoperative blood transfusion volume (median, 17,200 mL; range, 15,750 to 30,360 mL) administered to patients who developed intracerebral hemorrhage postoperatively was significantly greater than that (median, 6,990 mL; range, 1,840 to 22,680 mL) for patients without the complication (P =.0008). Massive intraoperative transfusion (>15,000 mL) was required in all 5 patients (100%) with intracerebral hemorrhage but only 9 of 72 patients (12.5%) in the other group (P =.0001). Four of 5 patients (80%) with intracerebral hemorrhage had intraoperative hypotension compared with 7 of 72 patients (9.7%) in the other group (P =.001). No significant difference was found in age, prothrombin time (PT), activated partial thromboplastin time (APTT), incidence of hypertension, bleeding at extracerebral sites, cyclosporine A neurotoxicity, thrombocytopenia, hemodialysis, and sepsis between the patients with and without intracerebral bleeding. However, the median cumulative score of coagulation parameters (PT, APTT, platelet count) was significantly greater in the group with than without intracerebral bleeding (median score, 3 v 1; P =.023). Intracerebral hemorrhage is 1 of the most disastrous complications after OLT. Intraoperative hypotension, massive intraoperative transfusion, and coagulopathy may be correlated with this complication.
