门静脉高压症患者围手术期血小板、凝血和纤溶变化的临床意义

Clinical significance of perioperative alternations of platelet, coagulation,and fibrinolysis in patients with portal hypertension

目的 探讨肝硬化合并门静脉高压 (PHT )的不同Child分级患者围手术期血小板数、凝血和纤溶指标变化的临床意义。 方法 对PHT组 17例ChildB级和 6例ChildC级患者分别行部分门体分流术和贲门周围血管离断术治疗 ,测定围手术期血小板、凝血和纤溶指标 ,并与无PHT的肝硬化患者对比。 结果 术前PHT组ChildB级患者除血小板数量下降外 ,其他反映血小板功能、凝血和纤溶指标与对照组比较均差异无显著性 (P >0 .0 5 ) ;而ChildC级患者除血小板数量下降外 ,GMP -14 0 ,FPA和D-二聚体明显增高 ( P <0 .0 5 )。术后PHT组ChildC级患者血小板数量及凝血因子Ⅷ :C均较B级组显著下降 (P <0 .0 5 ) ,GMP -14 0在ChildB级组中明显升高 ,而在ChildC级却明显下降。 结论 手术有诱发ChildC级患者并发DIC的可能 ,术中Fg和FⅧ

Objective To study the clinical significance of platelet, coagulation ,and fibrinolysis alteration in perioperative period in patients with different Child classifications of cirrhosis. Methods Alterations on the platelet count and the indices of coagulation and fibrinolysis in 17 cases of Child B class who underwent portal-systemic shunt, and 6 cases of Child C class who underwent portal-azygus vein disconnection were detected. Results Before operation,except the decrease in platelet count, there as no significant difference in the indices of other platelet function, coagulation and fibrinolysis in patients with Child B class compared with control group. While in patients with Child C class, the platelet count decreased, and GMP-140, FPA and D-dimer increased greatly. After operation, GMP-140 increased in patients with Child B class, while decreased in patients with child C class. The platelet count and factorⅧ:C in patients with Child C class decreased significantly compared with those with Child B class. Conclusions Operation may induce DIC in patients with Child C class, so it is necessary to determine the fibrinogen and factorⅧ:C during the operation.
