Abstract： 目的:研究肝硬化患者门静脉血栓(portal veinthrombosis,PVT)形成的相关危险因素.方法:2006-2007年我院确诊的肝炎和酒精性肝硬化患者90例,其中23例肝硬化PVT患者作为血栓组,67例肝硬化非血栓患者作为对照组.采用凝固法检测凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)和纤维蛋白原(Fib),发色底物法检测抗凝血酶-Ⅲ(AT-Ⅲ),酶联免疫吸附双抗体夹心法检测蛋白-C(PC)、蛋白-S(PS)、D-二聚体(d-dimer)、组织纤溶酶原激活物剂(t-PA)和组织纤溶酶原激活物抑制剂-I(PAI-1).将门静脉血栓形成的相关因素纳入研究,进行统计学分析.结果:d-dimer升高是肝硬化PVT形成的危险因素(OR=13.236,95%CI:2.345-74.721),PC和AT-Ⅲ升高是肝硬化PVT形成的保护因素(OR=0.242,95%CI:0.08-0.727;OR=0.917,95%CI:0.841-0.999).研究未能提示性别、肝功能Child-Pugh分级和APTT等止凝血指标是PVT形成的危险因素.结论:d-dimer升高是肝硬化PVT形成的危险因素,PC和AT-Ⅲ升高是肝硬化PVT形成的保护因素.
