老年门静脉高压症PCDV手术前后K_(ICG)研究

The study of K ICG in patients with portal hyertension in the elderly before and after PCDV

目的进一步提高老年肝硬化门静脉高压症的手术治疗效果。方法采用吲哚氰绿血浆清除率（简称ＫＩＣＧ）为指标，研究了老年肝硬化、门静脉高压症患者在进行ＰＣＤＶ手术前、后ＫＩＣＧ的变化，并与同类中年患者进行比较分析。结果老年肝硬化、门静脉高压症患者ＰＣＤＶ手术前、后ＫＩＣＧ无显著差异（Ｐ＞０．０５），且均低于中年同类患者（Ｐ＜０．０５）。结论（１）ＰＣＤＶ手术对老年肝硬化门静脉高压症患者的肝脏机能和肝脏储备能力影响不大，可做为首选术式。（２）ＫＩＣＧ可做为老年肝硬化门静脉高压症患者手术前确切了解肝脏机能状态和肝脏实际储备能力的可靠指标。（３）ＫＩＣＧ可做为老年肝硬化门脉高压症患者手术前选择手术适应症的指标。（４）ＫＩＣＧ可做为老年肝硬化门脉高压症患者判定手术预后，指导临床治疗的可靠指标。

Plasma indocyanine green clearance(K ICG ) were measured in patients with portal hypertension in the elderly before and after pericardial devascularization(PCDV) and compared with the middle aged patients with portal hypertension. It was found that there was no change in K ICG after the patients underwent pericardial devascularization(portoazygous disconnection). There was a significant decrease of K ICG compared with the middle aged patients of portal hypertension (P<0 05) .
