Surgical therapy for portal hypertension (PHT) in patients with cirrhosis has long been controversial,and various operative approaches have been used to prevent or manage such lethal complications as gastroesophageal variceal hemorrhage. However, over a century various portazygos devascularization and shunt approaches have been developed or modified, but the therapeutic effects have not been satisfactory till 1963 when Starzl did the first liver transplantation in the world, which provides a new hope to the surgical treatment of PHT.  相似文献

原发性肝癌合并严重肝硬化门脉高压的外科处理   总被引:9,自引:0,他引:9  
回顾性分析63例原发性肝癌合并严重肝硬化的外科处理,提出术前评估肝硬化程度及肝功能贮备的必要性,推荐“三联手术”即在处理原发病灶手术基础上对门脉高压和脾亢行脾动脉结扎加胃底贲门周围静脉结扎术;强调围手术期常规应用速尿,抗酸药,胰岛素等,结果:按此原则处理的32例患者三年生存率达57%,故认为“三关手术”代替脾切除是处理原发性肝癌合并严重肝硬化时防治消化道出血和脾亢的首选方法。  相似文献

目的 探讨影响肝硬化患者门脉高压性胃病(portal hypertension gastropathy, PHG)的临床特点及其进展的相关因素。方法 回顾性分析61例肝硬化患者内镜检查结果。将患者分成PHG组(43例)和非PHG组(18例),比较分析两组年龄、性别、白蛋白、肝功能、总胆红素、肌酐水平、门静脉内径宽度、凝血功能。探讨并发PHG及食管静脉曲张(esophageal varices, EV)等的情况。结果 61例肝硬化患者中,EV 60例(98.3%),PHG 43例(70.5%)。PHG的发病率和严重程度随着EV的严重程度及肝功能分级的增加呈上升趋势(P<0.05),且EV程度是PHG的独立危险因素(OR=2.726,95%CI: 1.140~6.519)。结论 肝硬化患者PHG发病率及严重程度与EV严重程度及肝功能分级升高及呈正相关。  相似文献

甲氰咪胍对肝硬化门脉高压症犬门脉血液动力学的影响   总被引:2,自引:0,他引:2  
目的:探讨甲氰咪胍对肝硬化门脉高压症犬门脉血液动力学的影响。 方法:以胆总管结扎法成功制备胆汁性肝硬化门脉高压症模型犬11只,随机分为两组,即甲氰咪胍组(n=7)和盐水对照组(n=4);另取4只正常犬作正常对照组。经股动脉、股静脉、右颈外静脉分别插管,以多导生理记录仪、电磁流量计等检测门脉及全身血液动力学变化,使用RF-3000型荧光分光光度计测量血浆组织胺浓度。 结果:甲氰咪胍组静脉注射甲氰咪胍(剂量0.012 g•kg-1)5、15、30、60、90和120 min后,自由门脉压平均值分别较注射前下降5.2%、14.1%、13.7%、12.9%、9.3%和6.5%(P<0.05,P<0.01,P<0.01,P<0.01,P<0.01,P<0.05),肝静脉楔入压、肝静脉压梯度、门静脉阻力均同步下降。肝动脉血流量无显著改变,门静脉血流量及全肝血流量轻度增多。肝静脉自由压、下腔静脉压、腹主动脉平均压及心率均无明显变化。自由门静脉压下降最大幅度与股静脉血血浆组织胺浓度呈显著正相关(r=0.787 4,P<0.05)。盐水对照组及正常对照组上述各指标均无显著变化。 结论:甲氰咪胍通过拮抗肝硬化门脉高压症犬血中异常升高的组织胺的作用,舒张肝血管床,降低门脉血流阻力,从而降低门脉压力,同时使门脉及全肝血流量轻度增加,而对全身血流动力学无不良影响。  相似文献
