目的探讨3种不同肝血流阻断方式在肝肿瘤切除术中的应用。方法将74例肝肿瘤患者根据肝血流阻断方式分为3组:A组(n=40)行pringle法,B组(n=23)行全肝血流阻断(THVE),C组(n=11)行解剖性肝血流(肝动脉、门静脉及肝静脉)阻断。并观察3组肝血...目的探讨3种不同肝血流阻断方式在肝肿瘤切除术中的应用。方法将74例肝肿瘤患者根据肝血流阻断方式分为3组:A组(n=40)行pringle法,B组(n=23)行全肝血流阻断(THVE),C组(n=11)行解剖性肝血流(肝动脉、门静脉及肝静脉)阻断。并观察3组肝血流阻断时间、手术时间、出血量及并发症等情况。结果A组和B组手术时间均较C组显著缩短(均P<0.01),B组肝门阻断前1 min和肝门开放后1 min中心静脉压均显著高于肝门阻断后(均P<0.01),B组和C组出血量均较A组显著减少(均P<0.01),A组和B组术后3 d ALT、AST水平均较C组显著升高(均P<0.01),3组肝血流阻断后均未发生肾脏及心血管系统并发症。结论肝肿瘤行肝切除术时行pringle法血流阻断是一种简便方法,但出血量多;全肝血流阻断是一种减少出血的有效方法;解剖性肝血流阻断技术要求高,但术中肝损伤小,可避免缺血-再灌注损伤。展开更多
