肝移植后并发桥脑中央髓鞘溶解症三例

目的总结肝移植后并发桥脑中央髓鞘溶解症(CPM)的诊治体会。方法回顾性分析3例肝移植后并发CPM的临床资料。结果例1于术后第18d出现定向障碍、四肢抽搐,随之昏迷,症状出现前后血电解质在正常范围;例2于术后第6d出现昏迷,有明显的低钠血症;例3于术后第7d出现意识模糊、被害妄想,随之昏迷,症状出现前后血电解质在正常范围。3例患者均经头颅磁共振检查诊断为CPM,虽经积极治疗,但最后均死亡。结论肝移植后并发CPM的原因是多方面的,其预后差,病死率高;磁共振是诊断CPM的首选方法。

Central pontine myelinolysis after liver transplantation: report of three cases
