低温无血切肝术
hypothermia isolated hepatectomy
指将肝脏血流完全阻断的同时，用低温灌注液灌注肝脏的技术作肝切除的方法。是Fortner在1970年首先采用的。方法：除肝十二指肠韧带外，离断肝脏周围韧带并结扎之；完全游离肝脏；分离肝动脉、门脉，游离出肝上、下的下腔静脉；由胃十二指动脉插管至肝固有动脉，门脉穿刺插管至分叉处，该两管同接一“Y”形管，依照顺序无损伤地阻断肝动脉、门脉、肝下下腔静脉、肝上下腔静脉，随后经“Y”形管的导管注入冷灌注液；并在肝下下腔静脉的前壁作一小切口，置入一导管，将灌注肝脏后的冷灌洗液由此放出；使肝脏充分冷却后，进行肝切除术。创面彻底止血后，除去肝下下腔静脉导管，缝合切口；去除肝下、肝上下腔静脉的阻断钳；拔除门脉处的导管，缝合其切口；开放门脉、肝动脉阻断钳；可拔掉或保留胃十二指肠动脉的导管。此手术适应于第1或第2肝门区肿瘤切除，或复杂的肝切除。但其技术复杂，难以掌握，仅可在少数有条件的医院中开展。
