摘要
报道４１例肝外胆管阻塞（Ａ组）和４１例单纯胆囊结石（Ｂ组）患者门脉血流与胆道动力学、门脉血流动力学和系统性血流动力学指标的逐步回归分析。结果表明，在Ａ组ＴＢ增高是影响ＢＴＰ的唯一因素，回归方程和偏回归系数的Ｆ检验，Ｐ＜０．０１；ＴＢ和ＢＴＰ增高是影响系统性血流动力学和门脉血质动力学的始动因素，ＳＶＲ降低是影响ＰＶＢＦ的关键因素；门脉的形态学和门脉压力变化也是影响因素之一，建立的回归方程经下检验，Ｐ＜０．０１，表明各自的回归方程的线性关系非常显著。因此，及早解除胆道高压，消除影响ＰＶＢＦ的始动因素，改善末梢血管阻力，是梗阻性黄疸围手术期处理的关键。
Reporting relationship between portal vein blood flow(PV-BF)and biliary tract dynamics &portal、systemic hemodynamics(an-alyzed by stepwise regression,in 41 cases each of extrahepatic bile duct obstruction(group A)& sim-ple gallbladder stones(gruop B). The findings indicated that, in group A, increase of total bilirubin(TB)was the sole factor affecting bile duct pressure(ETP),regres-sion equations & partial coefficient both very obviously different as shown by F test(P<0.01); the inc-rease of TB & BTP were initiative factors and decrease of stroke vessel resistance was the key factor which influenced systemic & portal hemodynamics morphological & pre-ssure of portal vein changes was also one of the influencing factors,the regression equations were very significantly different as shown by F test(P<0.01).Therefore,the early relief of biliary tract obstru-ction,elimination of those initia-tive factors affecting PVBF and im-provement of peripher al vessel resi-stance are keys to improve liver function &PVBF in treating perio-perative obstructive jaundice.
